L3 offload requires implementing FIB notifier for switch device, which is responsible for handling FIB events and rule changes. The notifier callback is invoked when interface initializes, or some new IP route adds. In this case, the notifier should handle add/delete route and make appropriate configuration on HW side. The L3 HW offload on S4 R-Switch is implemented using MFWD L3 routing, perfect filters, and L23 update table. When the IP routing callback is invoked, it adds a new route via Perfect filters to the existing interface and caches information about which packets can be routed using this interface. When packets go from R-Switch to outside they firstly come to rx_learning_chain, where they will be analyzed, and if match with cached before routing rules, the appropriate L3 rule will be added via L3 IPv4/v6 hash extract. After that, packets that match this stream ID will be forwarded to the appropriate destination port with updating destination MAC and TTL via L23 Update logic.

This commit extends list of TC flower filter match parameters, that are available for HW offload to R-Switch: EtherType, IP proto, ToS and TTL. Also, usage of perfect filter was optimized by checking parameters necessity (if mask for matching is equal to 0 - parameter is not needed). Signed-off-by: Dmytro Firsov <[email protected]>
This commit changes define names that are used in R-Switch driver to less generic for avoiding collisions. Signed-off-by: Dmytro Firsov <[email protected]>
This commit adds support of matching by L4 src/dst port for HW offloaded tc rules in R-Switch. Signed-off-by: Dmytro Firsov <[email protected]>

This commit removes ACTION_SKBMOD, that was used also for pedit actions. It was substituted with generic name ACTION_CHANGE_DMAC - single action, that is supported for both pedit and skbmod. Signed-off-by: Dmytro Firsov <[email protected]>
This commit adds additional check for ndev, that are received as target_dev for redirect in tc filters. This ndev should be one of the R-Switch ports (tsn0, tsn1...). Signed-off-by: Dmytro Firsov <[email protected]>
This commit removes parameter, that was not used from rswitch_tc_flower_validate_match() fuction prototype. Signed-off-by: Dmytro Firsov <[email protected]>
This commit adds new action for R-Switch TC flower filter. Now supported actions are drop and mirror redirect (also with dst MAC change). Signed-off-by: Dmytro Firsov <[email protected]>
Kernel TC subsystem somewhy always adds IPv6 flag to IPv4 rule match dissector, but true IPv6 is not currently supported by R-Switch driver for offload. IPv6 rules does not contain IPv4 flag in dissector, so this commit adds correct check to validation process. Signed-off-by: Dmytro Firsov <[email protected]>

… filter This commit introduces offloaded matching by 802.1Q VLAN fields for R-Switch TC flower filter. It uses C-Tag filtering mode and allows to match by VLAN ID and VLAN priority fields in hardware. Signed-off-by: Dmytro Firsov <[email protected]>
…all filters This commit adds implementation for hardware offload of traffic control VLAN modify actions for R-Switch flower and matchall filters. It uses L23 C-Tag update feature and now supports only 802.1Q VLANs. Signed-off-by: Dmytro Firsov <[email protected]>
This commit fixes VLAN actions validation. Previously the wrong byte order was used and it caused unexpected '-EOPNOTSUPP' for VLAN actions. Signed-off-by: Dmytro Firsov <[email protected]>
…river This commit corrects TC_SETUP_BLOCK logic, that is used for adding new TC rules to R-Switch driver. Currently driver supports only rules for ingress qdisc, so egress rules were handled incorrectly. Also flow_block_cb_setup_simple() should be called both for flow block binding and unbinding. Previously it was ignored for unbinding, it probably leaded to wrong content of driver block list. Signed-off-by: Dmytro Firsov <[email protected]> Signed-off-by: Dmytro Firsov <[email protected]>
At the current state of matchall and u32 filter they will accept any number of unsupported action when atleast one supported action is amongst them. Fix this by returning EOPNOTSUPP when we can't match action to any of the supported ones. Signed-off-by: Mykyta Poturai <[email protected]>
Add support for vlan id and priority modification to u32 filter. Fix skbmod check to allow for more than one action before redirect. Signed-off-by: Mykyta Poturai <[email protected]>
Move shared code from flower and matchall filters to common file. Signed-off-by: Mykyta Poturai <[email protected]>
This commit removes issue with SLV value, that defines traffic sources for TC drop action in u32 and flower filters. Previously, it was applied to traffic from all sources (all TSNx and GWCAx). Now it is set only for device, that was specified by traffic control rule. Signed-off-by: Dmytro Firsov <[email protected]>
This commit adds implementation of S-tag filtering for flower traffic control filter. It allows to offload 802.1ad match rules to R-Switch hardware.
