This is 'iw', a tool to use nl80211.


To build iw, just enter 'make'. If that fails, set the
PKG_CONFIG_PATH environment variable to allow the Makefile
to find libnl.


'iw' is currently maintained at http://git.sipsolutions.net/iw.git/,
some more documentation is available at
http://wireless.kernel.org/en/users/Documentation/iw.

Please send all patches to Johannes Berg <johannes@sipsolutions.net>
and CC linux-wireless@vger.kernel.org for community review.

	 *
	 * It is possible for a connect result message from another
	 * connect attempt to be processed here first, because we
	 * start listening to the multicast group before starting
	 * our own connect request, which may succeed but we get a
	 * fail message from a previous attempt that raced with us,
	 * or similar.
	 *
	 * The only proper way to fix this would be to listen to events
	 * before sending the command, and for the kernel to send the
	 * connect request or a cookie along with the event, so that you
	 * can match up whether the connect _you_ requested was finished
	 * or aborted.
	 *
	 * Alas, the kernel doesn't do that (yet).

/**
 * DOC: Station handling
 *
 * Stations are added per interface, but a special case exists with VLAN
 * interfaces. When a station is bound to an AP interface, it may be moved
 * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
 * The station is still assumed to belong to the AP interface it was added
 * to.
 *
 * Station handling varies per interface type and depending on the driver's
 * capabilities.
 *
 * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
 * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
 *  - a setup station entry is added, not yet authorized, without any rate
 *    or capability information, this just exists to avoid race conditions
 *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
 *    to add rate and capability information to the station and at the same
 *    time mark it authorized.
 *  - %NL80211_TDLS_ENABLE_LINK is then used
 *  - after this, the only valid operation is to remove it by tearing down
 *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)
 *

/**
 * DOC: Frame transmission/registration support
 *
 * Frame transmission and registration support exists to allow userspace
 * management entities such as wpa_supplicant react to management frames
 * that are not being handled by the kernel. This includes, for example,
 * certain classes of action frames that cannot be handled in the kernel
 * for various reasons.
 *
 * Frame registration is done on a per-interface basis and registrations
 * cannot be removed other than by closing the socket. It is possible to
 * specify a registration filter to register, for example, only for a
 * certain type of action frame. In particular with action frames, those
 * that userspace registers for will not be returned as unhandled by the
 * driver, so that the registered application has to take responsibility
 * for doing that.
 *
 * The type of frame that can be registered for is also dependent on the
 * driver and interface type. The frame types are advertised in wiphy
 * attributes so applications know what to expect.
 *
 * NOTE: When an interface changes type while registrations are active,
 *       these registrations are ignored until the interface type is
 *       changed again. This means that changing the interface type can
 *       lead to a situation that couldn't otherwise be produced, but
 *       any such registrations will be dormant in the sense that they
 *       will not be serviced, i.e. they will not receive any frames.
 *
 * Frame transmission allows userspace to send for example the required
 * responses to action frames. It is subject to some sanity checking,
 * but many frames can be transmitted. When a frame was transmitted, its
 * status is indicated to the sending socket.
 *
 * For more technical details, see the corresponding command descriptions
 * below.

/**
 * DOC: Virtual interface / concurrency capabilities
 *
 * Some devices are able to operate with virtual MACs, they can have
 * more than one virtual interface. The capability handling for this
 * is a bit complex though, as there may be a number of restrictions
 * on the types of concurrency that are supported.
 *
 * To start with, each device supports the interface types listed in
 * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
 * types there no concurrency is implied.
 *
 * Once concurrency is desired, more attributes must be observed:
 * To start with, since some interface types are purely managed in
 * software, like the AP-VLAN type in mac80211 for example, there's
 * an additional list of these, they can be added at any time and
 * are only restricted by some semantic restrictions (e.g. AP-VLAN
 * cannot be added without a corresponding AP interface). This list
 * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
 *
 * Further, the list of supported combinations is exported. This is
 * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
 * it exports a list of "groups", and at any point in time the
 * interfaces that are currently active must fall into any one of
 * the advertised groups. Within each group, there are restrictions
 * on the number of interfaces of different types that are supported
 * and also the number of different channels, along with potentially
 * some other restrictions. See &enum nl80211_if_combination_attrs.
 *
 * All together, these attributes define the concurrency of virtual
 * interfaces that a given device supports.

 * DOC: packet coalesce support
 *
 * In most cases, host that receives IPv4 and IPv6 multicast/broadcast

 * reception of these unwanted packets causes unnecessary processing
 * and power consumption.
 *
 * Packet coalesce feature helps to reduce number of received interrupts
 * to host by buffering these packets in firmware/hardware for some

 * a) Expiration of hardware timer whose expiration time is set to maximum
 * coalescing delay of matching coalesce rule.
 * b) Coalescing buffer in hardware reaches it's limit.
 * c) Packet doesn't match any of the configured coalesce rules.
 *
 * User needs to configure following parameters for creating a coalesce
 * rule.
 * a) Maximum coalescing delay
 * b) List of packet patterns which needs to be matched
 * c) Condition for coalescence. pattern 'match' or 'no match'
 * Multiple such rules can be created.

 * preshared key authentication. In %NL80211_CMD_CONNECT the preshared

 * For 802.1X the PMK or PMK-R0 are set by providing %NL80211_ATTR_PMK

 * eventually do a key derivation as per IEEE 802.11ai. The below additional
 * parameters should be given to driver in %NL80211_CMD_CONNECT and/or in
 * %NL80211_CMD_UPDATE_CONNECT_PARAMS.
 *	%NL80211_ATTR_FILS_ERP_USERNAME - used to construct keyname_nai
 *	%NL80211_ATTR_FILS_ERP_REALM - used to construct keyname_nai
 *	%NL80211_ATTR_FILS_ERP_NEXT_SEQ_NUM - used to construct erp message
 *	%NL80211_ATTR_FILS_ERP_RRK - used to generate the rIK and rMSK
 * rIK should be used to generate an authentication tag on the ERP message and
 * rMSK should be used to derive a PMKSA.
 * rIK, rMSK should be generated and keyname_nai, sequence number should be used
 * as specified in IETF RFC 6696.
 *
 * When FILS shared key authentication is completed, driver needs to provide the
 * below additional parameters to userspace, which can be either after setting
 * up a connection or after roaming.
 *	%NL80211_ATTR_FILS_KEK - used for key renewal
 *	%NL80211_ATTR_FILS_ERP_NEXT_SEQ_NUM - used in further EAP-RP exchanges
 *	%NL80211_ATTR_PMKID - used to identify the PMKSA used/generated
 *	%Nl80211_ATTR_PMK - used to update PMKSA cache in userspace
 * The PMKSA can be maintained in userspace persistently so that it can be used
 * later after reboots or wifi turn off/on also.
 *
 * %NL80211_ATTR_FILS_CACHE_ID is the cache identifier advertized by a FILS
 * capable AP supporting PMK caching. It specifies the scope within which the
 * PMKSAs are cached in an ESS. %NL80211_CMD_SET_PMKSA and
 * %NL80211_CMD_DEL_PMKSA are enhanced to allow support for PMKSA caching based
 * on FILS cache identifier. Additionally %NL80211_ATTR_PMK is used with
 * %NL80211_SET_PMKSA to specify the PMK corresponding to a PMKSA for driver to
 * use in a FILS shared key connection with PMKSA caching.

 *	%NL80211_ATTR_REASON_CODE can optionally be used to specify which type
 *	of disconnection indication should be sent to the station
 *	(Deauthentication or Disassociation frame and reason code for that
 *	frame).
 *
 * @NL80211_CMD_GET_MPATH: Get mesh path attributes for mesh path to
 * 	destination %NL80211_ATTR_MAC on the interface identified by

 * @NL80211_CMD_SET_BSS: Set BSS attributes for BSS identified by
 *	%NL80211_ATTR_IFINDEX.
 *
 * @NL80211_CMD_GET_REG: ask the wireless core to send us its currently set
 *	regulatory domain. If %NL80211_ATTR_WIPHY is specified and the device
 *	has a private regulatory domain, it will be returned. Otherwise, the
 *	global regdomain will be returned.
 *	A device will have a private regulatory domain if it uses the
 *	regulatory_hint() API. Even when a private regdomain is used the channel
 *	information will still be mended according to further hints from
 *	the regulatory core to help with compliance. A dump version of this API
 *	is now available which will returns the global regdomain as well as
 *	all private regdomains of present wiphys (for those that have it).
 *	If a wiphy is self-managed (%NL80211_ATTR_WIPHY_SELF_MANAGED_REG), then
 *	its private regdomain is the only valid one for it. The regulatory
 *	core is not used to help with compliance in this case.
 * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
 *	after being queried by the kernel. CRDA replies by sending a regulatory
 *	domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
 *	current alpha2 if it found a match. It also provides
 * 	NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each
 * 	regulatory rule is a nested set of attributes  given by
 * 	%NL80211_ATTR_REG_RULE_FREQ_[START|END] and
 * 	%NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by
 * 	%NL80211_ATTR_REG_RULE_POWER_MAX_ANT_GAIN and
 * 	%NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
 * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
 * 	to the specified ISO/IEC 3166-1 alpha2 country code. The core will
 * 	store this as a valid request and then query userspace for it.
 *
 * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the
 *	interface identified by %NL80211_ATTR_IFINDEX
 *
 * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
 *      interface identified by %NL80211_ATTR_IFINDEX
 *
 * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
 *	interface is identified with %NL80211_ATTR_IFINDEX and the management
 *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
 *	added to the end of the specified management frame is specified with
 *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
 *	added to all specified management frames generated by
 *	kernel/firmware/driver.
 *	Note: This command has been removed and it is only reserved at this
 *	point to avoid re-using existing command number. The functionality this
 *	command was planned for has been provided with cleaner design with the
 *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
 *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
 *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
 *
 * @NL80211_CMD_GET_SCAN: get scan results
 * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
 *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
 *	probe requests at CCK rate or not. %NL80211_ATTR_BSSID can be used to
 *	specify a BSSID to scan for; if not included, the wildcard BSSID will
 *	be used.
 * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
 *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
 * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
 *	partial scan results may be available
 *
 * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
 *	intervals and certain number of cycles, as specified by
 *	%NL80211_ATTR_SCHED_SCAN_PLANS. If %NL80211_ATTR_SCHED_SCAN_PLANS is
 *	not specified and only %NL80211_ATTR_SCHED_SCAN_INTERVAL is specified,
 *	scheduled scan will run in an infinite loop with the specified interval.
 *	These attributes are mutually exculsive,
 *	i.e. NL80211_ATTR_SCHED_SCAN_INTERVAL must not be passed if
 *	NL80211_ATTR_SCHED_SCAN_PLANS is defined.
 *	If for some reason scheduled scan is aborted by the driver, all scan
 *	plans are canceled (including scan plans that did not start yet).
 *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
 *	are passed, they are used in the probe requests.  For
 *	broadcast, a broadcast SSID must be passed (ie. an empty
 *	string).  If no SSID is passed, no probe requests are sent and
 *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
 *	if passed, define which channels should be scanned; if not
 *	passed, all channels allowed for the current regulatory domain
 *	are used.  Extra IEs can also be passed from the userspace by
 *	using the %NL80211_ATTR_IE attribute.  The first cycle of the
 *	scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
 *	is supplied. If the device supports multiple concurrent scheduled
 *	scans, it will allow such when the caller provides the flag attribute
 *	%NL80211_ATTR_SCHED_SCAN_MULTI to indicate user-space support for it.
 * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
 *	scheduled scan is not running. The caller may assume that as soon
 *	as the call returns, it is safe to start a new scheduled scan again.
 * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
 *	results available.
 * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
 *	stopped.  The driver may issue this event at any time during a
 *	scheduled scan.  One reason for stopping the scan is if the hardware
 *	does not support starting an association or a normal scan while running
 *	a scheduled scan.  This event is also sent when the
 *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
 *	is brought down while a scheduled scan was running.
 *
 * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
 *      or noise level
 * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
 *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
 *
 * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry using %NL80211_ATTR_MAC
 *	(for the BSSID), %NL80211_ATTR_PMKID, and optionally %NL80211_ATTR_PMK
 *	(PMK is used for PTKSA derivation in case of FILS shared key offload) or
 *	using %NL80211_ATTR_SSID, %NL80211_ATTR_FILS_CACHE_ID,
 *	%NL80211_ATTR_PMKID, and %NL80211_ATTR_PMK in case of FILS
 *	authentication where %NL80211_ATTR_FILS_CACHE_ID is the identifier
 *	advertized by a FILS capable AP identifying the scope of PMKSA in an
 *	ESS.
 * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
 *	(for the BSSID) and %NL80211_ATTR_PMKID or using %NL80211_ATTR_SSID,
 *	%NL80211_ATTR_FILS_CACHE_ID, and %NL80211_ATTR_PMKID in case of FILS
 *	authentication.
 * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
 *
 * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
 * 	has been changed and provides details of the request information
 * 	that caused the change such as who initiated the regulatory request
 * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
 * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
 * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
 * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
 * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
 * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
 * 	to (%NL80211_ATTR_REG_ALPHA2).
 * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
 * 	has been found while world roaming thus enabling active scan or
 * 	any mode of operation that initiates TX (beacons) on a channel
 * 	where we would not have been able to do either before. As an example
 * 	if you are world roaming (regulatory domain set to world or if your
 * 	driver is using a custom world roaming regulatory domain) and while
 * 	doing a passive scan on the 5 GHz band you find an AP there (if not
 * 	on a DFS channel) you will now be able to actively scan for that AP
 * 	or use AP mode on your card on that same channel. Note that this will
 * 	never be used for channels 1-11 on the 2 GHz band as they are always
 * 	enabled world wide. This beacon hint is only sent if your device had
 * 	either disabled active scanning or beaconing on a channel. We send to
 * 	userspace the wiphy on which we removed a restriction from
 * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
 * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
 * 	the beacon hint was processed.
 *
 * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
 *	This command is used both as a command (request to authenticate) and
 *	as an event on the "mlme" multicast group indicating completion of the
 *	authentication process.
 *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
 *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
 *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
 *	the SSID (mainly for association, but is included in authentication
 *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
 *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
 *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
 *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
 *	to be added to the frame.
 *	When used as an event, this reports reception of an Authentication
 *	frame in station and IBSS modes when the local MLME processed the
 *	frame, i.e., it was for the local STA and was received in correct
 *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
 *	MLME SAP interface (kernel providing MLME, userspace SME). The
 *	included %NL80211_ATTR_FRAME attribute contains the management frame
 *	(including both the header and frame body, but not FCS). This event is
 *	also used to indicate if the authentication attempt timed out. In that
 *	case the %NL80211_ATTR_FRAME attribute is replaced with a
 *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
 *	pending authentication timed out).
 * @NL80211_CMD_ASSOCIATE: association request and notification; like
 *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
 *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
 *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives). The
 *	%NL80211_ATTR_PREV_BSSID attribute is used to specify whether the
 *	request is for the initial association to an ESS (that attribute not
 *	included) or for reassociation within the ESS (that attribute is
 *	included).
 * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
 *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
 *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
 *	primitives).
 * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
 *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
 *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
 *
 * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
 *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
 *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
 *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
 *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
 *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
 *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
 *
 * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
 *	FREQ attribute (for the initial frequency if no peer can be found)
 *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
 *	should be fixed rather than automatically determined. Can only be
 *	executed on a network interface that is UP, and fixed BSSID/FREQ
 *	may be rejected. Another optional parameter is the beacon interval,
 *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
 *	given defaults to 100 TU (102.4ms).
 * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
 *	determined by the network interface.
 *
 * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
 *	to identify the device, and the TESTDATA blob attribute to pass through
 *	to the driver.
 *
 * @NL80211_CMD_CONNECT: connection request and notification; this command
 *	requests to connect to a specified network but without separating
 *	auth and assoc steps. For this, you need to specify the SSID in a
 *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
 *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
 *	%NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
 *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
 *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT,
 *	%NL80211_ATTR_CONTROL_PORT_OVER_NL80211, %NL80211_ATTR_MAC_HINT, and
 *	%NL80211_ATTR_WIPHY_FREQ_HINT.
 *	If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
 *	restrictions on BSS selection, i.e., they effectively prevent roaming
 *	within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
 *	can be included to provide a recommendation of the initial BSS while
 *	allowing the driver to roam to other BSSes within the ESS and also to
 *	ignore this recommendation if the indicated BSS is not ideal. Only one
 *	set of BSSID,frequency parameters is used (i.e., either the enforcing
 *	%NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
 *	%NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
 *	%NL80211_ATTR_PREV_BSSID can be used to request a reassociation within
 *	the ESS in case the device is already associated and an association with
 *	a different BSS is desired.
 *	Background scan period can optionally be
 *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
 *	if not specified default background scan configuration
 *	in driver is used and if period value is 0, bg scan will be disabled.
 *	This attribute is ignored if driver does not support roam scan.
 *	It is also sent as an event, with the BSSID and response IEs when the
 *	connection is established or failed to be established. This can be
 *	determined by the %NL80211_ATTR_STATUS_CODE attribute (0 = success,
 *	non-zero = failure). If %NL80211_ATTR_TIMED_OUT is included in the
 *	event, the connection attempt failed due to not being able to initiate
 *	authentication/association or not receiving a response from the AP.
 *	Non-zero %NL80211_ATTR_STATUS_CODE value is indicated in that case as
 *	well to remain backwards compatible.
 *	When establishing a security association, drivers that support 4 way
 *	handshake offload should send %NL80211_CMD_PORT_AUTHORIZED event when
 *	the 4 way handshake is completed successfully.
 * @NL80211_CMD_ROAM: Notification indicating the card/driver roamed by itself.
 *	When a security association was established with the new AP (e.g. if
 *	the FT protocol was used for roaming or the driver completed the 4 way
 *	handshake), this event should be followed by an
 *	%NL80211_CMD_PORT_AUTHORIZED event.
 * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
 *	userspace that a connection was dropped by the AP or due to other
 *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
 *	%NL80211_ATTR_REASON_CODE attributes are used.
 *
 * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
 *	associated with this wiphy must be down and will follow.
 *
 * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
 *	channel for the specified amount of time. This can be used to do
 *	off-channel operations like transmit a Public Action frame and wait for
 *	a response while being associated to an AP on another channel.
 *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
 *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
 *	frequency for the operation.
 *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
 *	to remain on the channel. This command is also used as an event to
 *	notify when the requested duration starts (it may take a while for the
 *	driver to schedule this time due to other concurrent needs for the
 *	radio).
 *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
 *	that will be included with any events pertaining to this request;
 *	the cookie is also used to cancel the request.
 * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
 *	pending remain-on-channel duration if the desired operation has been
 *	completed prior to expiration of the originally requested duration.
 *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
 *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
 *	uniquely identify the request.
 *	This command is also used as an event to notify when a requested
 *	remain-on-channel duration has expired.
 *
 * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
 *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
 *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
 *
 * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
 *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
 *	requires an interface index, a frame type attribute (optional for
 *	backward compatibility reasons, if not given assumes action frames)
 *	and a match attribute containing the first few bytes of the frame
 *	that should match, e.g. a single byte for only a category match or
 *	four bytes for vendor frames including the OUI. The registration
 *	cannot be dropped, but is removed automatically when the netlink
 *	socket is closed. Multiple registrations can be made.
 * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
 *	backward compatibility
 * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
 *	command is used both as a request to transmit a management frame and
 *	as an event indicating reception of a frame that was not processed in
 *	kernel code, but is for us (i.e., which may need to be processed in a
 *	user space application). %NL80211_ATTR_FRAME is used to specify the
 *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
 *	to indicate on which channel the frame is to be transmitted or was
 *	received. If this channel is not the current channel (remain-on-channel
 *	or the operational channel) the device will switch to the given channel
 *	and transmit the frame, optionally waiting for a response for the time
 *	specified using %NL80211_ATTR_DURATION. When called, this operation
 *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
 *	TX status event pertaining to the TX request.
 *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
 *	management frames at CCK rate or not in 2GHz band.
 *	%NL80211_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
 *	counters which will be updated to the current value. This attribute
 *	is used during CSA period.
 * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
 *	command may be used with the corresponding cookie to cancel the wait
 *	time if it is known that it is no longer necessary.
 * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
 * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
 *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
 *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
 *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
 *	the frame.
 * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
 *	backward compatibility.
 *
 * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
 * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
 *
 * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
 *	is used to configure connection quality monitoring notification trigger
 *	levels.
 * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
 *	command is used as an event to indicate the that a trigger level was
 *	reached.
 * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
 *	and the attributes determining channel width) the given interface
 *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
 *	In case multiple channels are supported by the device, the mechanism
 *	with which it switches channels is implementation-defined.
 *	When a monitor interface is given, it can only switch channel while
 *	no other interfaces are operating to avoid disturbing the operation
 *	of any other interfaces, and other interfaces will again take
 *	precedence when they are used.
 *
 * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
 *
 * @NL80211_CMD_SET_MULTICAST_TO_UNICAST: Configure if this AP should perform
 *	multicast to unicast conversion. When enabled, all multicast packets
 *	with ethertype ARP, IPv4 or IPv6 (possibly within an 802.1Q header)
 *	will be sent out to each station once with the destination (multicast)
 *	MAC address replaced by the station's MAC address. Note that this may
 *	break certain expectations of the receiver, e.g. the ability to drop
 *	unicast IP packets encapsulated in multicast L2 frames, or the ability
 *	to not send destination unreachable messages in such cases.
 *	This can only be toggled per BSS. Configure this on an interface of
 *	type %NL80211_IFTYPE_AP. It applies to all its VLAN interfaces
 *	(%NL80211_IFTYPE_AP_VLAN), except for those in 4addr (WDS) mode.
 *	If %NL80211_ATTR_MULTICAST_TO_UNICAST_ENABLED is not present with this
 *	command, the feature is disabled.
 *
 * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
 *	mesh config parameters may be given.
 * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
 *	network is determined by the network interface.
 *
 * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
 *	notification. This event is used to indicate that an unprotected
 *	deauthentication frame was dropped when MFP is in use.
 * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
 *	notification. This event is used to indicate that an unprotected
 *	disassociation frame was dropped when MFP is in use.
 *
 * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
 *      beacon or probe response from a compatible mesh peer.  This is only
 *      sent while no station information (sta_info) exists for the new peer
 *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
 *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
 *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
 *      notification, userspace may decide to create a new station
 *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
 *      reoccurring, the userspace authentication daemon may want to create the
 *      new station with the AUTHENTICATED flag unset and maybe change it later
 *      depending on the authentication result.
 *
 * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
 * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
 *	Since wireless is more complex than wired ethernet, it supports
 *	various triggers. These triggers can be configured through this
 *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
 *	more background information, see
 *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
 *	The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
 *	from the driver reporting the wakeup reason. In this case, the
 *	@NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
 *	for the wakeup, if it was caused by wireless. If it is not present
 *	in the wakeup notification, the wireless device didn't cause the
 *	wakeup but reports that it was woken up.
 *
 * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
 *	the necessary information for supporting GTK rekey offload. This
 *	feature is typically used during WoWLAN. The configuration data
 *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
 *	contains the data in sub-attributes). After rekeying happened,
 *	this command may also be sent by the driver as an MLME event to
 *	inform userspace of the new replay counter.
 *
 * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
 *	of PMKSA caching dandidates.
 *
 * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
 *	In addition, this can be used as an event to request userspace to take
 *	actions on TDLS links (set up a new link or tear down an existing one).
 *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
 *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
 *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
 *	%NL80211_TDLS_TEARDOWN).
 * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
 *	%NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
 *	sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
 *	802.11 management frames, while TDLS action codes (802.11-2012
 *	8.5.13.1) will be encapsulated and sent as data frames. The currently
 *	supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
 *	and the currently supported TDLS actions codes are given in
 *	&enum ieee80211_tdls_actioncode.
 *
 * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
 *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
 *	implement sending deauth to stations that send unexpected class 3
 *	frames. Also used as the event sent by the kernel when such a frame
 *	is received.
 *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
 *	other attributes like the interface index are present.
 *	If used as the command it must have an interface index and you can
 *	only unsubscribe from the event by closing the socket. Subscription
 *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
 *
 * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
 *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
 *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
 *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
 *
 * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
 *	by sending a null data frame to it and reporting when the frame is
 *	acknowleged. This is used to allow timing out inactive clients. Uses
 *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
 *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
 *	up the event with the request. The event includes the same data and
 *	has %NL80211_ATTR_ACK set if the frame was ACKed.
 *
 * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
 *	other BSSes when any interfaces are in AP mode. This helps implement
 *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
 *	messages. Note that per PHY only one application may register.
 *
 * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
 *      No Acknowledgement Policy should be applied.
 *
 * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
 *	independently of the userspace SME, send this event indicating
 *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
 *	attributes determining channel width.  This indication may also be
 *	sent when a remotely-initiated switch (e.g., when a STA receives a CSA
 *	from the remote AP) is completed;
 *
 * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
 *	has been started on an interface, regardless of the initiator
 *	(ie. whether it was requested from a remote device or
 *	initiated on our own).  It indicates that
 *	%NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
 *	after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's.  The userspace may
 *	decide to react to this indication by requesting other
 *	interfaces to change channel as well.
 *
 * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
 *	its %NL80211_ATTR_WDEV identifier. It must have been created with
 *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
 *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
 *	public action frame TX.
 * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
 *	its %NL80211_ATTR_WDEV identifier.
 *
 * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
 *	notify userspace that AP has rejected the connection request from a
 *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
 *	is used for this.
 *
 * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
 *	for IBSS or MESH vif.
 *
 * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
 *	This is to be used with the drivers advertising the support of MAC
 *	address based access control. List of MAC addresses is passed in
 *	%NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
 *	%NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
 *	is not already done. The new list will replace any existing list. Driver
 *	will clear its ACL when the list of MAC addresses passed is empty. This
 *	command is used in AP/P2P GO mode. Driver has to make sure to clear its
 *	ACL list during %NL80211_CMD_STOP_AP.
 *
 * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
 *	a radar is detected or the channel availability scan (CAC) has finished
 *	or was aborted, or a radar was detected, usermode will be notified with
 *	this event. This command is also used to notify userspace about radars
 *	while operating on this channel.
 *	%NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
 *	event.
 *
 * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
 *	i.e. features for the nl80211 protocol rather than device features.
 *	Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
 *
 * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
 *	Information Element to the WLAN driver
 *
 * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
 *	to the supplicant. This will carry the target AP's MAC address along
 *	with the relevant Information Elements. This event is used to report
 *	received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
 *
 * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
 *	a critical protocol that needs more reliability in the connection to
 *	complete.
 *
 * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
 *	return back to normal.
 *
 * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
 * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
 *
 * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
 *	the new channel information (Channel Switch Announcement - CSA)
 *	in the beacon for some time (as defined in the
 *	%NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
 *	new channel. Userspace provides the new channel information (using
 *	%NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
 *	width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
 *	other station that transmission must be blocked until the channel
 *	switch is complete.
 *
 * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
 *	by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
 *	%NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
 *	%NL80211_ATTR_VENDOR_DATA.
 *	For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
 *	used in the wiphy data as a nested attribute containing descriptions
 *	(&struct nl80211_vendor_cmd_info) of the supported vendor commands.
 *	This may also be sent as an event with the same attributes.
 *
 * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
 *	The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
 *	that attribute is not included, QoS mapping is disabled. Since this
 *	QoS mapping is relevant for IP packets, it is only valid during an
 *	association. This is cleared on disassociation and AP restart.
 *
 * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
 *	%NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
 *	and %NL80211_ATTR_ADMITTED_TIME parameters.
 *	Note that the action frame handshake with the AP shall be handled by
 *	userspace via the normal management RX/TX framework, this only sets
 *	up the TX TS in the driver/device.
 *	If the admitted time attribute is not added then the request just checks
 *	if a subsequent setup could be successful, the intent is to use this to
 *	avoid setting up a session with the AP when local restrictions would
 *	make that impossible. However, the subsequent "real" setup may still
 *	fail even if the check was successful.
 * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
 *	and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
 *	before removing a station entry entirely, or before disassociating
 *	or similar, cleanup will happen in the driver/device in this case.
 *
 * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
 *	destination %NL80211_ATTR_MAC on the interface identified by
 *	%NL80211_ATTR_IFINDEX.
 *
 * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
 *	bandwidth of a channel must be given.
 * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
 *	network is determined by the network interface.
 *
 * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
 *	identified by the %NL80211_ATTR_MAC parameter. A target channel is
 *	provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
 *	channel width/type. The target operating class is given via
 *	%NL80211_ATTR_OPER_CLASS.
 *	The driver is responsible for continually initiating channel-switching
 *	operations and returning to the base channel for communication with the
 *	AP.
 * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
 *	peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
 *	when this command completes.
 *
 * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
 *	as an event to indicate changes for devices with wiphy-specific regdom
 *	management.
 *
 * @NL80211_CMD_ABORT_SCAN: Stop an ongoing scan. Returns -ENOENT if a scan is
 *	not running. The driver indicates the status of the scan through
 *	cfg80211_scan_done().
 *
 * @NL80211_CMD_START_NAN: Start NAN operation, identified by its
 *	%NL80211_ATTR_WDEV interface. This interface must have been
 *	previously created with %NL80211_CMD_NEW_INTERFACE. After it
 *	has been started, the NAN interface will create or join a
 *	cluster. This command must have a valid
 *	%NL80211_ATTR_NAN_MASTER_PREF attribute and optional
 *	%NL80211_ATTR_BANDS attributes.  If %NL80211_ATTR_BANDS is
 *	omitted or set to 0, it means don't-care and the device will
 *	decide what to use.  After this command NAN functions can be
 *	added.
 * @NL80211_CMD_STOP_NAN: Stop the NAN operation, identified by
 *	its %NL80211_ATTR_WDEV interface.
 * @NL80211_CMD_ADD_NAN_FUNCTION: Add a NAN function. The function is defined
 *	with %NL80211_ATTR_NAN_FUNC nested attribute. When called, this
 *	operation returns the strictly positive and unique instance id
 *	(%NL80211_ATTR_NAN_FUNC_INST_ID) and a cookie (%NL80211_ATTR_COOKIE)
 *	of the function upon success.
 *	Since instance ID's can be re-used, this cookie is the right
 *	way to identify the function. This will avoid races when a termination
 *	event is handled by the user space after it has already added a new
 *	function that got the same instance id from the kernel as the one
 *	which just terminated.
 *	This cookie may be used in NAN events even before the command
 *	returns, so userspace shouldn't process NAN events until it processes
 *	the response to this command.
 *	Look at %NL80211_ATTR_SOCKET_OWNER as well.
 * @NL80211_CMD_DEL_NAN_FUNCTION: Delete a NAN function by cookie.
 *	This command is also used as a notification sent when a NAN function is
 *	terminated. This will contain a %NL80211_ATTR_NAN_FUNC_INST_ID
 *	and %NL80211_ATTR_COOKIE attributes.
 * @NL80211_CMD_CHANGE_NAN_CONFIG: Change current NAN
 *	configuration. NAN must be operational (%NL80211_CMD_START_NAN
 *	was executed).  It must contain at least one of the following
 *	attributes: %NL80211_ATTR_NAN_MASTER_PREF,
 *	%NL80211_ATTR_BANDS.  If %NL80211_ATTR_BANDS is omitted, the
 *	current configuration is not changed.  If it is present but
 *	set to zero, the configuration is changed to don't-care
 *	(i.e. the device can decide what to do).
 * @NL80211_CMD_NAN_FUNC_MATCH: Notification sent when a match is reported.
 *	This will contain a %NL80211_ATTR_NAN_MATCH nested attribute and
 *	%NL80211_ATTR_COOKIE.
 *
 * @NL80211_CMD_UPDATE_CONNECT_PARAMS: Update one or more connect parameters
 *	for subsequent roaming cases if the driver or firmware uses internal
 *	BSS selection. This command can be issued only while connected and it
 *	does not result in a change for the current association. Currently,
 *	only the %NL80211_ATTR_IE data is used and updated with this command.
 *
 * @NL80211_CMD_SET_PMK: For offloaded 4-Way handshake, set the PMK or PMK-R0
 *	for the given authenticator address (specified with %NL80211_ATTR_MAC).
 *	When %NL80211_ATTR_PMKR0_NAME is set, %NL80211_ATTR_PMK specifies the
 *	PMK-R0, otherwise it specifies the PMK.
 * @NL80211_CMD_DEL_PMK: For offloaded 4-Way handshake, delete the previously
 *	configured PMK for the authenticator address identified by
 *	%NL80211_ATTR_MAC.
 * @NL80211_CMD_PORT_AUTHORIZED: An event that indicates that the 4 way
 *	handshake was completed successfully by the driver. The BSSID is
 *	specified with %NL80211_ATTR_MAC. Drivers that support 4 way handshake
 *	offload should send this event after indicating 802.11 association with
 *	%NL80211_CMD_CONNECT or %NL80211_CMD_ROAM. If the 4 way handshake failed
 *	%NL80211_CMD_DISCONNECT should be indicated instead.
 *
 * @NL80211_CMD_CONTROL_PORT_FRAME: Control Port (e.g. PAE) frame TX request
 *	and RX notification.  This command is used both as a request to transmit
 *	a control port frame and as a notification that a control port frame
 *	has been received. %NL80211_ATTR_FRAME is used to specify the
 *	frame contents.  The frame is the raw EAPoL data, without ethernet or
 *	802.11 headers.
 *	When used as an event indication %NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
 *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT and %NL80211_ATTR_MAC are added
 *	indicating the protocol type of the received frame; whether the frame
 *	was received unencrypted and the MAC address of the peer respectively.
 *
 * @NL80211_CMD_RELOAD_REGDB: Request that the regdb firmware file is reloaded.
 *
 * @NL80211_CMD_EXTERNAL_AUTH: This interface is exclusively defined for host
 *	drivers that do not define separate commands for authentication and
 *	association, but rely on user space for the authentication to happen.
 *	This interface acts both as the event request (driver to user space)
 *	to trigger the authentication and command response (userspace to
 *	driver) to indicate the authentication status.
 *
 *	User space uses the %NL80211_CMD_CONNECT command to the host driver to
 *	trigger a connection. The host driver selects a BSS and further uses
 *	this interface to offload only the authentication part to the user
 *	space. Authentication frames are passed between the driver and user
 *	space through the %NL80211_CMD_FRAME interface. Host driver proceeds
 *	further with the association after getting successful authentication
 *	status. User space indicates the authentication status through
 *	%NL80211_ATTR_STATUS_CODE attribute in %NL80211_CMD_EXTERNAL_AUTH
 *	command interface.
 *
 *	Host driver reports this status on an authentication failure to the
 *	user space through the connect result as the user space would have
 *	initiated the connection through the connect request.
 *
 * @NL80211_CMD_STA_OPMODE_CHANGED: An event that notify station's
 *	ht opmode or vht opmode changes using any of %NL80211_ATTR_SMPS_MODE,
 *	%NL80211_ATTR_CHANNEL_WIDTH,%NL80211_ATTR_NSS attributes with its
 *	address(specified in %NL80211_ATTR_MAC).
 *
 * @NL80211_CMD_GET_FTM_RESPONDER_STATS: Retrieve FTM responder statistics, in
 *	the %NL80211_ATTR_FTM_RESPONDER_STATS attribute.
 *
 * @NL80211_CMD_PEER_MEASUREMENT_START: start a (set of) peer measurement(s)
 *	with the given parameters, which are encapsulated in the nested
 *	%NL80211_ATTR_PEER_MEASUREMENTS attribute. Optionally, MAC address
 *	randomization may be enabled and configured by specifying the
 *	%NL80211_ATTR_MAC and %NL80211_ATTR_MAC_MASK attributes.
 *	If a timeout is requested, use the %NL80211_ATTR_TIMEOUT attribute.
 *	A u64 cookie for further %NL80211_ATTR_COOKIE use is is returned in
 *	the netlink extended ack message.
 *
 *	To cancel a measurement, close the socket that requested it.
 *
 *	Measurement results are reported to the socket that requested the
 *	measurement using @NL80211_CMD_PEER_MEASUREMENT_RESULT when they
 *	become available, so applications must ensure a large enough socket
 *	buffer size.
 *
 *	Depending on driver support it may or may not be possible to start
 *	multiple concurrent measurements.
 * @NL80211_CMD_PEER_MEASUREMENT_RESULT: This command number is used for the
 *	result notification from the driver to the requesting socket.
 * @NL80211_CMD_PEER_MEASUREMENT_COMPLETE: Notification only, indicating that
 *	the measurement completed, using the measurement cookie
 *	(%NL80211_ATTR_COOKIE).
 *
 * @NL80211_CMD_NOTIFY_RADAR: Notify the kernel that a radar signal was
 *	detected and reported by a neighboring device on the channel
 *	indicated by %NL80211_ATTR_WIPHY_FREQ and other attributes
 *	determining the width and type.
 *
 * @NL80211_CMD_MAX: highest used command number
 * @__NL80211_CMD_AFTER_LAST: internal use

 *	Setting %NL80211_MFP_OPTIONAL with a %NL80211_CMD_CONNECT request will
 *	let the driver (or the firmware) decide whether to use MFP or not.

 *	station mode. If the flag is included in %NL80211_CMD_ASSOCIATE
 *	request, the driver will assume that the port is unauthorized until
 *	authorized by user space. Otherwise, port is marked authorized by
 *	default in station mode.
 * @NL80211_ATTR_CONTROL_PORT_ETHERTYPE: A 16-bit value indicating the
 *	ethertype that will be used for key negotiation. It can be
 *	specified with the associate and connect commands. If it is not

 *	port frames (e.g. of type given in %NL80211_ATTR_CONTROL_PORT_ETHERTYPE)
 *	will be sent directly to the network interface or sent via the NL80211
 *	socket.  If this attribute is missing, then legacy behavior of sending
 *	control port frames directly to the network interface is used.  If the
 *	flag is included, then control port frames are sent over NL80211 instead
 *	using %CMD_CONTROL_PORT_FRAME.  If control port routing over NL80211 is
 *	to be used then userspace must also use the %NL80211_ATTR_SOCKET_OWNER

 *
 * @NL80211_ATTR_GENERATION: Used to indicate consistent snapshots for
 *	dumps. This number increases whenever the object list being
 *	dumped changes, and as such userspace can verify that it has
 *	obtained a complete and consistent snapshot by verifying that
 *	all dump messages contain the same generation number. If it
 *	changed then the list changed and the dump should be repeated
 *	completely from scratch.
 *
 * @NL80211_ATTR_4ADDR: Use 4-address frames on a virtual interface

 *	rates based on negotiated supported rates information. This attribute
 *	is used with %NL80211_CMD_SET_TX_BITRATE_MASK and with starting AP,
 *	and joining mesh networks (not IBSS yet). In the later case, it must
 *	specify just a single bitrate, which is to be used for the beacon.
 *	The driver must also specify support for this with the extended
 *	features NL80211_EXT_FEATURE_BEACON_RATE_LEGACY,
 *	NL80211_EXT_FEATURE_BEACON_RATE_HT and
 *	NL80211_EXT_FEATURE_BEACON_RATE_VHT.

 *
 * @NL80211_ATTR_LOCAL_STATE_CHANGE: Flag attribute to indicate that a command
 *	is requesting a local authentication/association state change without
 *	invoking actual management frame exchange. This can be used with
 *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_DEAUTHENTICATE,

 *
 * @NL80211_ATTR_WIPHY_ANTENNA_TX: Bitmap of allowed antennas for transmitting.
 *	This can be used to mask out antennas which are not attached or should
 *	not be used for transmitting. If an antenna is not selected in this
 *	bitmap the hardware is not allowed to transmit on this antenna.
 *
 *	Each bit represents one antenna, starting with antenna 1 at the first
 *	bit. Depending on which antennas are selected in the bitmap, 802.11n
 *	drivers can derive which chainmasks to use (if all antennas belonging to
 *	a particular chain are disabled this chain should be disabled) and if
 *	a chain has diversity antennas wether diversity should be used or not.
 *	HT capabilities (STBC, TX Beamforming, Antenna selection) can be
 *	derived from the available chains after applying the antenna mask.
 *	Non-802.11n drivers can derive wether to use diversity or not.
 *	Drivers may reject configurations or RX/TX mask combinations they cannot
 *	support by returning -EINVAL.
 *
 * @NL80211_ATTR_WIPHY_ANTENNA_RX: Bitmap of allowed antennas for receiving.
 *	This can be used to mask out antennas which are not attached or should
 *	not be used for receiving. If an antenna is not selected in this bitmap
 *	the hardware should not be configured to receive on this antenna.
 *	For a more detailed description see @NL80211_ATTR_WIPHY_ANTENNA_TX.
 *
 * @NL80211_ATTR_WIPHY_ANTENNA_AVAIL_TX: Bitmap of antennas which are available

 *	transmitted on another channel when the channel given doesn't match
 *	the current channel. If the current channel doesn't match and this
 *	flag isn't set, the frame will be rejected. This is also used as an
 *	nl80211 capability flag.
 *
 * @NL80211_ATTR_BSS_HT_OPMODE: HT operation mode (u16)
 *
 * @NL80211_ATTR_KEY_DEFAULT_TYPES: A nested attribute containing flags
 *	attributes, specifying what a key should be set as default as.
 *	See &enum nl80211_key_default_types.
 *
 * @NL80211_ATTR_MESH_SETUP: Optional mesh setup parameters.  These cannot be
 *	changed once the mesh is active.
 * @NL80211_ATTR_MESH_CONFIG: Mesh configuration parameters, a nested attribute
 *	containing attributes from &enum nl80211_meshconf_params.
 * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver

 *	triggers.
 *
 * @NL80211_ATTR_SCHED_SCAN_INTERVAL: Interval between scheduled scan
 *	cycles, in msecs.
 *
 * @NL80211_ATTR_SCHED_SCAN_MATCH: Nested attribute with one or more
 *	sets of attributes to match during scheduled scans.  Only BSSs
 *	that match any of the sets will be reported.  These are
 *	pass-thru filter rules.
 *	For a match to succeed, the BSS must match all attributes of a
 *	set.  Since not every hardware supports matching all types of
 *	attributes, there is no guarantee that the reported BSSs are
 *	fully complying with the match sets and userspace needs to be
 *	able to ignore them by itself.
 *	Thus, the implementation is somewhat hardware-dependent, but
 *	this is only an optimization and the userspace application
 *	needs to handle all the non-filtered results anyway.
 *	If the match attributes don't make sense when combined with
 *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
 *	is included in the probe request, but the match attributes
 *	will never let it go through), -EINVAL may be returned.

 *       AMPDU density and AMPDU factor.
 *      All values are treated as suggestions and may be ignored
 *      by the driver as required.  The actual values may be seen in
 *      the station debugfs ht_caps file.
 *
 * @NL80211_ATTR_DFS_REGION: region for regulatory rules which this country

 *	authentication algorithms that need special fields to be added into
 *	the frames (SAE and FILS). Currently, only the SAE cases use the
 *	initial two fields (Authentication transaction sequence number and

/**
 * DOC: TCP connection wakeup
 *
 * Some devices can establish a TCP connection in order to be woken up by a
 * packet coming in from outside their network segment, or behind NAT. If
 * configured, the device will establish a TCP connection to the given
 * service, and periodically send data to that service. The first data
 * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
 * The data packets can optionally include a (little endian) sequence
 * number (in the TCP payload!) that is generated by the device, and, also
 * optionally, a token from a list of tokens. This serves as a keep-alive
 * with the service, and for NATed connections, etc.
 *
 * During this keep-alive period, the server doesn't send any data to the
 * client. When receiving data, it is compared against the wakeup pattern
 * (and mask) and if it matches, the host is woken up. Similarly, if the
 * connection breaks or cannot be established to start with, the host is
 * also woken up.
 *
 * Developer's note: ARP offload is required for this, otherwise TCP
 * response packets might not go through correctly.

 *	apply to interfaces purely managed in software, which are listed
 *	in a separate attribute %NL80211_ATTR_INTERFACES_SOFTWARE.
 * @NL80211_IFACE_COMB_STA_AP_BI_MATCH: flag attribute specifying that

 *	infrastructure and AP/GO combinations, i.e. the GO(s) must adopt
 *	the infrastructure network's beacon interval.
 * @NL80211_IFACE_COMB_NUM_CHANNELS: u32 attribute specifying how many
 *	different channels may be used within this group.
 * @NL80211_IFACE_COMB_RADAR_DETECT_WIDTHS: u32 attribute containing the bitmap

 *	=> allows an AP and a STA that must match BIs
 *
 *	numbers = [ #{AP, P2P-GO} <= 8 ], BI min gcd, channels = 1, max = 8,

 * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested
 *	to work properly to suppport receiving regulatory hints from
 *	cellular base stations.
 * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: (no longer available, only
 *	here to reserve the value for API/ABI compatibility)
 * @NL80211_FEATURE_SAE: This driver supports simultaneous authentication of
 *	equals (SAE) with user space SME (NL80211_CMD_AUTHENTICATE) in station
 *	mode
 * @NL80211_FEATURE_LOW_PRIORITY_SCAN: This driver supports low priority scan
 * @NL80211_FEATURE_SCAN_FLUSH: Scan flush is supported

 * @NL80211_FEATURE_VIF_TXPOWER: The driver supports per-vif TX power setting
 * @NL80211_FEATURE_NEED_OBSS_SCAN: The driver expects userspace to perform
 *	OBSS scans and generate 20/40 BSS coex reports. This flag is used only
 *	for drivers implementing the CONNECT API, for AUTH/ASSOC it is implied.

 *	state (to later be transitioned into authorized), with this flag
 *	they should be added before even sending the authentication reply
 *	and then transitioned into authenticated, associated and authorized
 *	states using station flags.
 *	Note that even for drivers that support this, the default is to add
 *	stations in authenticated/associated state, so to add unauthenticated
 *	stations the authenticated/associated bits have to be set in the mask.

 *	interface, but gets added to the driver. It ensures that incoming
 *	unicast packets directed at the configured interface address get ACKed.
 * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
 *	channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the
 *	lifetime of a BSS.
 * @NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES: This device adds a DS Parameter

 *	management TPC Report action frame, and in the Radio Measurement Link
 *	Measurement Report action frame.
 * @NL80211_FEATURE_ACKTO_ESTIMATION: This driver supports dynamic ACK timeout
 *	estimation (dynack). %NL80211_ATTR_WIPHY_DYN_ACK flag attribute is used
 *	to enable dynack.
 * @NL80211_FEATURE_STATIC_SMPS: Device supports static spatial
 *	multiplexing powersave, ie. can turn off all but one chain
 *	even on HT connections that should be using more chains.
 * @NL80211_FEATURE_DYNAMIC_SMPS: Device supports dynamic spatial
 *	multiplexing powersave, ie. can turn off all but one chain
 *	and then wake the rest up as required after, for example,
 *	rts/cts handshake.
 * @NL80211_FEATURE_SUPPORTS_WMM_ADMISSION: the device supports setting up WMM
 *	TSPEC sessions (TID aka TSID 0-7) with the %NL80211_CMD_ADD_TX_TS
 *	command. Standard IEEE 802.11 TSPEC setup is not yet supported, it
 *	needs to be able to handle Block-Ack agreements and other things.
 * @NL80211_FEATURE_MAC_ON_CREATE: Device supports configuring
 *	the vif's MAC address upon creation.
 *	See 'macaddr' field in the vif_params (cfg80211.h).
 * @NL80211_FEATURE_TDLS_CHANNEL_SWITCH: Driver supports channel switching when
 *	operating as a TDLS peer.
 * @NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR: This device/driver supports using a
 *	random MAC address during scan (if the device is unassociated); the
 *	%NL80211_SCAN_FLAG_RANDOM_ADDR flag may be set for scans and the MAC
 *	address mask/value will be used.
 * @NL80211_FEATURE_SCHED_SCAN_RANDOM_MAC_ADDR: This device/driver supports
 *	using a random MAC address for every scan iteration during scheduled
 *	scan (while not associated), the %NL80211_SCAN_FLAG_RANDOM_ADDR may
 *	be set for scheduled scan and the MAC address mask/value will be used.

 * requests.
 *
 * NL80211_SCAN_FLAG_LOW_SPAN, NL80211_SCAN_FLAG_LOW_POWER, and

 * one of them can be used in the request.
 *
 * @NL80211_SCAN_FLAG_LOW_PRIORITY: scan request has low priority
 * @NL80211_SCAN_FLAG_FLUSH: flush cache before scanning
 * @NL80211_SCAN_FLAG_AP: force a scan even if the interface is configured
 *	as AP and the beaconing has already been configured. This attribute is
 *	dangerous because will destroy stations performance as a lot of frames
 *	will be lost while scanning off-channel, therefore it must be used only
 *	when really needed
 * @NL80211_SCAN_FLAG_RANDOM_ADDR: use a random MAC address for this scan (or
 *	for scheduled scan: a different one for every scan iteration). When the
 *	flag is set, depending on device capabilities the @NL80211_ATTR_MAC and
 *	@NL80211_ATTR_MAC_MASK attributes may also be given in which case only
 *	the masked bits will be preserved from the MAC address and the remainder
 *	randomised. If the attributes are not given full randomisation (46 bits,
 *	locally administered 1, multicast 0) is assumed.
 *	This flag must not be requested when the feature isn't supported, check
 *	the nl80211 feature flags for the device.
 * @NL80211_SCAN_FLAG_FILS_MAX_CHANNEL_TIME: fill the dwell time in the FILS
 *	request parameters IE in the probe request
 * @NL80211_SCAN_FLAG_ACCEPT_BCAST_PROBE_RESP: accept broadcast probe responses
 * @NL80211_SCAN_FLAG_OCE_PROBE_REQ_HIGH_TX_RATE: send probe request frames at
 *	rate of at least 5.5M. In case non OCE AP is discovered in the channel,
 *	only the first probe req in the channel will be sent in high rate.
 * @NL80211_SCAN_FLAG_OCE_PROBE_REQ_DEFERRAL_SUPPRESSION: allow probe request
 *	tx deferral (dot11FILSProbeDelay shall be set to 15ms)
 *	and suppression (if it has received a broadcast Probe Response frame,
 *	Beacon frame or FILS Discovery frame from an AP that the STA considers
 *	a suitable candidate for (re-)association - suitable in terms of
 *	SSID and/or RSSI.
 * @NL80211_SCAN_FLAG_LOW_SPAN: Span corresponds to the total time taken to
 *	accomplish the scan. Thus, this flag intends the driver to perform the
 *	scan request with lesser span/duration. It is specific to the driver
 *	implementations on how this is accomplished. Scan accuracy may get
 *	impacted with this flag.
 * @NL80211_SCAN_FLAG_LOW_POWER: This flag intends the scan attempts to consume
 *	optimal possible power. Drivers can resort to their specific means to
 *	optimize the power. Scan accuracy may get impacted with this flag.
 * @NL80211_SCAN_FLAG_HIGH_ACCURACY: Accuracy here intends to the extent of scan
 *	results obtained. Thus HIGH_ACCURACY scan flag aims to get maximum
 *	possible scan results. This flag hints the driver to use the best
 *	possible scan configuration to improve the accuracy in scanning.
 *	Latency and power use may get impacted with this flag.
 * @NL80211_SCAN_FLAG_RANDOM_SN: randomize the sequence number in probe
 *	request frames from this scan to avoid correlation/tracking being
 *	possible.
 * @NL80211_SCAN_FLAG_MIN_PREQ_CONTENT: minimize probe request content to
 *	only have supported rates and no additional capabilities (unless

	 * nl80211 socket to fix:
	 * It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or
	 * NL80211_CMD_SCAN_ABORTED message to be sent by the kernel
	 * before (!) we listen to it, because we only start listening
	 * after we send our scan request.
	 *
	 * Doing it the other way around has a race condition as well,
	 * if you first open the events socket you may get a notification
	 * for a previous scan.
	 *
	 * The only proper way to fix this would be to listen to events
	 * before sending the command, and for the kernel to send the
	 * scan request along with the event, so that you can match up
	 * whether the scan you requested was finished or aborted (this
	 * may result in processing a scan that another application
	 * requested, but that doesn't seem to be a problem).
	 *
	 * Alas, the kernel doesn't do that (yet).

/**
 * parse_freqchan - Parse frequency or channel definition
 *
 * @chandef: chandef structure to be filled in
 * @chan: Boolean whether to parse a channel or frequency based specifier
 * @argc: Number of arguments
 * @argv: Array of string arguments
 * @parsed: Pointer to return the number of used arguments, or NULL to error
 *          out if any argument is left unused.
 *
 * The given chandef structure will be filled in from the command line
 * arguments. argc/argv will be updated so that further arguments from the
 * command line can be parsed.
 *
 * Note that despite the fact that the function knows how many center freqs
 * are needed, there's an ambiguity if the next argument after this is an
 * integer argument, since the valid channel width values are interpreted
 * as such, rather than a following argument. This can be avoided by the
 * user by giving "NOHT" instead.
 *
 * The working specifier if chan is set are:
 *   <channel> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz]
 *
 * And if frequency is set:
 *   <freq> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz]
 *   <control freq> [5|10|20|40|80|80+80|160] [<center1_freq> [<center2_freq>]]
 *
 * If the mode/channel width is not given the NOHT is assumed.
 *
 * Return: Number of used arguments, zero or negative error number otherwise
