net: bridge: avoid VLAN lookups for flood neighbour suppression

Browse source

We can remove more unnecessary VLAN lookups if we pass the port-VLAN
entry to the neighbour suppression helpers so they can use it directly
instead of resolving it again. Use a vid wrapper for callers which don't
have the port-VLAN entry. This removes up to two additional VLAN hash
lookups per flooded egress port for packets marked as proxy replied.
