+Subject: [PATCH 04/50] ACS: Allow selecting a better channel when using
+ 40/80/160 MHz
+
+When considering a channel for a bandwidth of 40/80/160 MHZ on the 5 GHz
+or 6 GHz band, allow selecting one of the other channels in the segment
+instead of the first one. This is done only if the other channel's
+interference_factor is lower than the first one's.
