Subject: [PATCH] [24/223] mac80211: Fix ibss station got expired immediately

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Rajkumar Manoharan <rmanoharan@...eros.com>

commit c8716d9dc13c7f6ee92f2bfc6cc3b723b417bff8 upstream.

Station addition in ieee80211_ibss_rx_queued_mgmt is not updating
sta->last_rx which is causing station expiry in ieee80211_ibss_work
path. So sta addition and deletion happens repeatedly.
