Subject: [PATCH net-next 1/2] vlan: add proto for proc interface

The vlan could support 2 proto: 802.1q and 802.1ad, so add it to
proc interface, the user could easily distinguish the proto for
each vlan dev.

And the dev->priv_flags seems inappropriate, modify to Priv_Flags,
looks more comfortable.

---------------------- the old format: --------------------------
