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.
