Changes since v1: - removed noise and quality from station info in NL80211 - added bandwith to station info in NL80211 - changed name of patch file to nl80211ext_v2.patch The problem of a well defined signal strength value is still not addressed, but I have not enough knowledge about the driver specific implementations to make a good suggestion I think.
