Subject[PATCH] [16/223] mac80211: add helper for reseting the connection monitor
Date
2.6.35-longterm review patch.  If anyone has any objections, please let me know.

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

commit be099e82e9cf6d5d65d044e9ef6fc8bee3c7a113 upstream.

This will be used in another place later. The connection
monitor was added as of 2.6.35 so these fixes will be
applicable to >= 2.6.35.
