One of them is shown reversed comparing to another. E.g. 11:22:...:88 vs 88:...:22:11.

net iface is showing you the mac address, which is used by default to create the extended address.
But the extended address could be something else, it's possible to change it.

Extended address is taken from iface's 15.4 context, and that one has to be in little endian as 15.4 frames requires it.
Shell could show it the same way as mac, why not. I'll make sure the set ext addr assumes this same order so it will reverse it.

net/ieee802154: Shell handles extended address in EUI-64 format
8ef4653 
802.15.4, as other radio tech, works in little endian on network level.
To keeps things simple, the inner context per-interface, stores the
extended address that way. But it can be confusing in shell then, so
let's work handle these addreses through EUI-64 format there.

Fixes zephyrproject-rtos#4936
