Actually, that was the approach I thought about and went for first (and it would probably work for me). Just checking against the bridge device's net_device::dev_addr. I scratched it though, as I was afraid that the issue might still exist for people using some other upper device on top of the bridge device. For instance, macvlan? And iterating over the net_device::dev_addrs list seemed too costly for fast path to me.
