I think you will find you are bridging in promiscous mode and the
HW VLAN stuff isn't there. You should try to bridge the vlan devices
or disable the VLAN HW (driver hack). It works with the fxp0 since you
are using SW VLAN so the HW part isn't grabing it. I've done the driver
hack for some things I needed to do.
