-Subject: [PATCH] ath9k: limit retries for powersave response frames
-
-In some cases, the channel might be busy enough that an ath9k AP's
-response to PS-Poll frames might be too slow and the station has already
-gone to sleep. To avoid wasting too much airtime on this, limit the
-number of retries on such frames and ensure that no sample rate gets
-used.
