3.11.10.1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Larry Finger <Larry.Finger at lwfinger.net>
commit b4ade797668e33b4e8353c2701ce01d7084dfafa upstream.
The routine that processes received frames was returning the RSSI value for the
signal strength; however, that value is available only for associated APs. As
a result, the strength was the absurd value of 10 dBm. As a result, scans
return incorrect values for the strength, which causes unwanted attempts to roam.
This patch fixes https://bugzilla.kernel.org/show_bug.cgi?id=63881.
