[PATCH] bcm43xx: output proper link quality with scans

[PATCH] bcm43xx: output proper link quality with scans

[Larry Finger]

The bcm43xx-softmac driver fails to set two quantities needed for
iwlist to compute wireless quality when scanning. As a result, userland
programs using the quality to determine the best connection fail.
