To clarify further, if you want to bridge all VLANs on eth0 with eth1
just add eth0 and eth1 to the bridge. But that will assume that all
VIDs are the same on both ports.

If eth0.2 should be bridged with eth1.3 and so on, then you will need
one bridge per VLAN. Remember to set:
vconfig set_name_type DEV_PLUS_VID_NO_PAD

..if it isn't already set.

..and what happened to the vconfig set_bind_mode option that was
required for this? (Or did PER_DEVICE become the default, I seem to
recall this being the case?)
