This bug was there for years, however didn't cause any problems. It was
exposed recently by the 3.15 release by the:
commit 3afc2167f60a327a2c1e1e2600ef209a3c2b75b7
Author: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>
Date: Tue Mar 4 16:50:13 2014 +0200
cfg80211/mac80211: ignore signal if the frame was heard on wrong channel
Should we mark it for stable for 3.15 only? Or all olders kernels as well?
