This patch adds (as suggested by scott feldman),
         - new netlink attribute IFLA_BRIDGE_VLAN_INFO_LIST to represent
           vlan list
         - And bridge_vlan_info flags BRIDGE_VLAN_INFO_RANGE_START and
           BRIDGE_VLAN_INFO_RANGE_END to indicate start and end of vlan range

You add these here but you don't use them until the next patch.
If they were wrong a bisect would point to the next patch.

I would add them in the next patch where you start to use them.

I thought it was ok to declare it first and use them in the next patch. 
Only the other way around would be bad.
  I have submitted in a similar way before. If needed i will resubmit.
