I see.  I am using Open vSwitch instead of the linux bridging, so I've 
found that it's impossible to strip the 802.1q header before it egresses 
out of the switch to the domU.  I am going to try their latest version 
that includes native-untagged mode on trunk ports.  That way I can at 
least pass traffic for one single vlan without tags through the trunk.  
I think that my focus needs to be on the Open vSwitch side, since I 
assume it would be much easier to change the way they do access ports, 
then add vlan functionality to the GPLPV drivers.  If there is an easier 
way that I might be overlooking please let me know, otherwise I'll dig 
into ofproto and see what I can break.
Mike
