qtnfmac: track broadcast domain of each interface
If firmware reports that it supports hardware switch capabilities, driver needs to track and notify device whenever broadcast domain of a particular network device changes (ie. whenever it's upper master device changes). Firmware needs a unique ID to tell broadcast domains from each other which is an opaque number otherwise. For that purpose we can use netspace:ifidx pair to uniquely identify each broadcast domain: - if netdev is not part of a bridge, then use it's own ifidx as a broadcast domain ID - if netdev is part of a bridge, then use bridge netdev ifidx as broadcast domain ID Firmware makes sure that packets are only forwarded between interfaces marked with the same broadcast domain ID.
