It would be nice to be able to use VID 0 to mean untagged packets.
Hm, nice idea. I'll implement it in my next round of patches.
FYI: 802.1Q defines VLAN 1 as the 'native' LAN: all packets on VLAN 1
are *by definition* not encapsulated (according to my CCNA guide ;-))
VID 0 means "priority frames"
Perhaps we need to make sure that VID 1 means untagged ...
