Yeah, we figured that out...originally we weren't setting it from the PF 
side, just the VF.

I've upgraded to the latest igb driver but still no dice.

We've got tcpdump running on the bare VF devices (eth1) in both VMs. 
Trying to ping from the vlan device (eth1.42) to the vlan device in the 
other VM results in arps being sent out.  The tcpdump on the tx eth1 
shows vlan42, but on the rx side it doesn't.

Is there something that can cause the internal switch to strip the vlan 
header?
