Does the addm work now?

Do you mean bridge0 is not up if it is configured in rc.conf?

Things are a little bit complicated here, so I will need to talk to
other developers when I have a clear solution, but I have a temporary
workaround:
ifconfig xl0 promisc
ifconfig xl1 promisc


I have tested it with following configuration (I am short of cross
cables in home :P, so only one side is using vlan)
em0 <---> re0 | bridge0 | vlan0(nfe0) <---> vlan0(xl0)

nfe0 is in PPROMISC, i.e. ifconfig nfe0 promisc

Best Regards,
