ath_mgtstart: discard, no xmit buf
this little kernelmessage got me for months now,but after all i have at least 
worked out how to get around its mean impact. the message appears and the 
connection to the ap is lost,and stays that way till i ifconfig the card down 
and up. ive read a lot on this and it seems as if most people having this 
problem with madwifi and ar5212 based cards are using somewhat of an outdoor 
router setting doesnt matter much what kernel of madwifi version,use a quite 
new cvs. in my case the problem still occours ,but does not force me to remod 
the card up and down to keep the connection working-means if the 
transmitpower is high enough,the card somehow finds its way to the ap back 
instead of being stuck at scanning.and for most not so latency dependend 
connections this seems to be fast enough. so getting a larger antenna or an 
amplifier at least makes this somewhat usable. what i noticed is that the 
excessive retries the iwconfig output shows seem to are somewhat related to 
the problem,as i get much lesser of em when i have more power,and somewhat 
proportional to that lesser "ath_mgtstart: discard, no xmit buf" msgs. it 
just appears when a recent number of excessive retries has occured,and when 
the link quality goes below 20-21 (in my case) the connectioned wont be 
reetablished.i found this out after i had it working for no obvious reason 
but a larger antenna,some nights ago a fat storm ripped of the "roofcoating" 
of the wagon i live in,and with it my antenna.as i was repaired it - more 
kickin it back to work and wondered why my good old problem came back,for the 
reason that my a. lost about one third of its power after crashing to 
ground,i changed nothing within my wlan settings at this point,just gave my 
a. its power ,and some more, back. well after the final repair some hours ago 
i haven`t got any of these ugly msgs again even with heavy traffic. maybe it 
helps some people to save their nerves till this is fixed.
