mlxsw: spectrum_switchdev: Allow port enslavement to a VLAN-unaware bridge
Up until now we only allowed VLAN devices to be put in a VLAN-unaware bridge, but some users need the ability to enslave physical ports as well. This is achieved by mapping the port and VID 1 to the bridge's vFID, instead of the port and the VID used by the VLAN device. The above is valid because as long as the port is not enslaved to a bridge, VID 1 is guaranteed to be configured as PVID and egress untagged.
