I'd like to ask if have you managed to figure out this issue? I am 
facing more or less the same problem

I have set up multiple VLANs on my FreeBSD box and now would like to 
bridge WiFi adapter (wlan0) with only one vlan:

When I try to configure bridge:

% sudo ifconfig bridge create
% sudo ifconfig bridge addm wlan0
% sudo ifconfig bridge addm vlan1200
bridge0: error setting interface capabilities on vlan1200
% sudo ifconfig bridge stp wlan0
% sudo ifconfig bridge0 stp vlan1200
ifconfig: unable to set bridge flags: Invalid argument

% ifconfig bridge0
bridge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
         ether 02:8e:2e:18:3e:00
         nd6 options=9<PERFORMNUD,IFDISABLED>
         id 04:f0:21:0f:77:d7 priority 32768 hellotime 2 fwddelay 15
         maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200
         root id 04:f0:21:0f:77:d7 priority 32768 ifcost 0 port 0
         member: vlan1200 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
                 ifmaxaddr 0 port 6 priority 128 path cost 20000
         member: wlan0 flags=147<LEARNING,DISCOVER,STP,AUTOEDGE,AUTOPTP>
                 ifmaxaddr 0 port 11 priority 128 path cost 33333 proto rstp
                 role designated state discarding


If I change vlan1200 to physical interface, everything works without any 
problems..

Do you have any idea?

Cheers,

Marek
