> b. modify br_switchdev_port_vlan_add to pass bridge's vlan_proto to port driver
> c. enable NETIF_F_HW_VLAN_STAG_FILTER in ocelot driver
> v4:
> a. modify slave.c to support "ip set br0 type bridge vlan_protocol 802.1ad"

> v3: combine two patches to one post

Please defer new feature changes, like this, until the net-next tree is open
again.  It is closed right now.
