I have been playing with bridging with wi driver (in hostap mode) the last few days and have seen some interesting behavior. For one, performance falls through the floor. This seem related to promiscuous mode and maybe associated with hostap mode. Performance of ng_bridge and BRIDGE came out the same. On ng_bridge, I turned off promiscuous mode on the wi interface and things still worked. Performance also went back up to pre bridging levels. I have no idea why and haven't had time to play more. I haven't tried a Cisco card yet. Have a friend with one, will have to invite him over.
