Just a data point for people.  Have no idea if this information will be 
useful
to some people.

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.
