If the driver supports VLAN acceleration, it is usually on by default.
At least I can't tcpdump VLAN packets with intact VLAN tags on my
notebook's tg3 card -- even if I haven't loaded the 8021q module at
all. It's rather annoying, really.

Anyway, you need to explicitly turn off VLAN acceleration on the
devices added to such a bridge.
