[PATCH 3.2 048/185] rtlwifi: rtl8192cu: Fix incorrect signalstrength for unassociated AP

From: Ben Hutchings
Date: Sat Dec 28 2013 - 21:20:34 EST

3.2.54-rc1 review patch. If anyone has any objections, please let me know.


From: Larry Finger <Larry.Finger@xxxxxxxxxxxx>

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.
