This patch is a workaround for

mac80211: retry sending failed BAR frames later instead of tearing down
aggr (http://www.spinics.net/lists/linux-wireless/msg76379.html -
f0425beda4d404a6e751439b562100b902ba9c98)
See:
http://thread.gmane.org/gmane.linux.kernel.wireless.general/83297/focus=83304


Meanwhile there was a bug report complaining about problems with
be03d4a45 when used as STA:
http://thread.gmane.org/gmane.linux.drivers.rt2x00.user/1257
You can find there a few other workaround proposals.


Stanislaw Gruszka proposed here a final(?) workaround, which refines
workaround be03d4a45c by shrinking it to AP function:

carl9170 had the same problem with f0425beda. There it was fixed like
this:
http://thread.gmane.org/gmane.linux.kernel.wireless.general/100793/focus=1405
This approach fixes the real problem (no aggregation handling by the
firmware / hardware) by implementing it into the driver.

Unfortunately, I didn't see any implementation of c9122c0d63a50 for
rt2x00 until now.



Kind regards,
Andreas Hartmann
