Just to be sure that we talk about the same thing (and I feel like we are not),
I am not suggesting any modification to what's going on the wire. Just a new
virtual interface that captures only untagged packets.
To be more clear:
- igb0: receives all arriving packets, sends packets without inserting any VLAN
- igb0.1: receives arriving packets with VLAN tag 1, adds VLAN tag 1 when
- igb0.0: [proposed] receives only packets without any VLAN tag, sends packets
without inserting any VLAN tag
