> v4:
> a. modify slave.c to support "ip set br0 type bridge vlan_protocol 802.1ad"
> b. modify ocelot.c, if enable QinQ, set VLAN_AWARE_ENA and VLAN_POP_CNT per

> 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.
