Subject[PATCH] [23/223] mac80211: reset probe send counter upon connection timer reset
Date
2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Luis R. Rodriguez <lrodriguez@atheros.com>

commit 0c699c3a75d4e8d0d2c317f83048d8fd3ffe692a upstream.

Upon beacon loss we send probe requests after 30 seconds of idle
time and we wait for each probe response 1/2 second. We send a
total of 3 probe requests before giving up on the AP. In the case
that we reset the connection idle monitor we should reset the probe
requests count to 0. Right now this won't help in any way but
the next patch will.

This patch has fixes for stable kernel [2.6.35+].
