[PATCH 3/3] mac80211: recalc min_def chanctx even when chandef is identical
From: Arik Nemtsov The min_def chanctx is affected not only by the current chandef, but sometimes also by other stations on the vif. There's a valid scenario where a TDLS peer can widen its BW, thereby causing the min_def to increase.
