ath problems when in if_bridge mode

Hi

I find some problems when running ath cards in if_bridge mode.

I have continuous UP/DOWN events on the uplink card. The connection is really 
interrupted for a second or so which results in dns lookup errors 
downloads are going through, only the download speed is not stable

please look close, the problem is not on the hostap card

the problem is not hw related, I can switch both cards and the problem stays 
on the uplink card

I can take the bridge off and stay connected without UP/DOWN events (same 
machine/same HW)

the other wierd thing is that when I compile ath_rate_sample the both cards 
are working basicly but no traffic goes through the bridge, when I compile 
ath_rate_onoe the traffic goes through, when I take the bridge off and use 
the machine as router the traffic goes through.

the above does not change wether I put the uplink card in STP or not
I tried latest releng_6 i386 and amd64 and it is the same result

If you think I should check something please tell me

Jo?o

Bridging a wireless client is not supported, you can read this thread
for more into (especially the last couple of posts)

sorry for the delay I was underway

seems I posted the wrong ifconfig output but setting the uplink card into 
adhoc mode the same thing happens

I am not sure if this belongs to you Andrew but if I do not set the cards in 
bridge mode then the device up/down event do *not* appear, the uplink card 
stays connected without a word

soon I put it in if_bridge mode I have this continuous up/down events
