Add support for matching on VLAN tag in bridge offloads.
Currently only trunk mode is supported.

To enable VLAN filtering (existing FDB entries will be deleted):
ip link set $BR type bridge vlan_filtering 1

To add VLANs to bridge in trunk mode:
bridge vlan add dev $PF1 vid 110-111
bridge vlan add dev $VF1_PR vid 110-111
