3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andreas Hartmann <redacted>

commit be03d4a45c09ee5100d3aaaedd087f19bc20d01f upstream.

[...]

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.

OK, I'll drop this for now.  Once this is sorted out, please send to
stable a complete list of fixes that are needed.

To be clear, I have all of these in the queue:

be03d4a45c09 rt2x00: Don't let mac80211 send a BAR when an AMPDU subframe fails
5b632fe85ec8 mac80211: introduce IEEE80211_HW_TEARDOWN_AGGR_ON_BAR_FAIL
ab9d6e4ffe19 Revert: "rt2x00: Don't let mac80211 send a BAR when an AMPDU subframe fails"

and I'm intending to drop/defer them all.

Ben.

It is easier to change the specification to fit the program than vice versa.
