If anyone has any objections, please let me know. ------------------ From: Larry Finger 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. Signed-off-by: Larry Finger Reported-by: Matthieu Baerts Signed-off-by: John W.
