From: Johannes Berg <johannes.berg@intel.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 8ec6d97871f37e4743678ea4a455bd59580aa0f4 upstream.
The ifmgd->ave_beacon_signal value cannot be taken as is for
comparisons, it must be divided by since it's represented
like that for better accuracy of the EWMA calculations. This
would lead to invalid driver RSSI events. Fix the used value.
Fixes: 615f7b9bb1f8 ("mac80211: add driver RSSI threshold events")
