Subject: b43 : under high load, ack are lost

Hi,

I use a 4306 (core rev 5) with compat-wireless-2009-05-08 as wireless driver and
4.150.10.5 firmware.
My station is an airo card in wpa-psk mode (802.11b).

After resolving my beacon problem [1], when I download at max speed my station
disconnect from AP because "LostSync-MaxRetry".
After looking in my station statistic it seems the retry (RetryLong) are due to
noack received from the AP.

Who is responsible to generate ack ?
The firmware or the mac80211 stack ?

Any idea to investigate this ?

Thanks

Matthieu
