Hi,

Are there any problem with if_bridge in hostap mode? We have a FreeBSD 
6.1 runnig with 03 atheros cards (all atheros cards are in hostap mode) 
where 02 cards are bridged:

bridge0: flags=8043<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
        ether ac:de:48:0f:31:2a
        priority 32768 hellotime 2 fwddelay 15 maxage 20
        member: nve0 flags=3<LEARNING,DISCOVER>
        member: ath1 flags=3<LEARNING,DISCOVER>
        member: ath2 flags=3<LEARNING,DISCOVER>

In this server are happing some crahses like this:
