I'm not expecting it to deliver packets based on vlan membership, I'm just 
expecting the normal bridging behavior, but leaving the VLAN tags intact.  This 
seems to work fine for the e1000 and bnx2 drivers.  I'm just speculating but my 
guess is that the tg3 driver is stripping the tag before it even hits the 
bridge.
