3.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Larry Finger <Larry.Finger@lwfinger.net>
commit 78dbfecb95be4635b995af3bd29fa10013409fcd 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.
