Subject: [PATCH 3.11 045/233] rtlwifi: rtl8192c: Prevent reconnect attempts if not connected

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

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

From: Larry Finger <Larry.Finger@...inger.net>

commit 8fd77aec1a9d6f4328fc0244f21932114e066df3 upstream.

This driver has a watchdog timer that attempts to reconnect when beacon frames
are not seen for 6 seconds. This patch disables that reconnect whenever the
device has never been connected.
