Subject: [PATCH 05/10] mac80211: Add more ethtools stats: survey, rates, etc
From: Ben Greear <greearb@...delatech.com>
The signal and noise are forced to be positive since ethtool
deals in unsigned 64-bit values and this number should be human
readable. This gives easy access to some of the data formerly
exposed in the deprecated /proc/net/wireless file.
