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.
