mac80211: fix channel type recalculation with HT and non-HT interfaces
When running an AP interface along with the cooked monitor interface created by hostapd, adding an interface and deleting it again triggers a channel type recalculation during which the (non-HT) monitor interface takes precedence over the HT AP interface, thus causing the channel type to be set to non-HT. Fix this by ensuring that a more wide channel type will not be overwritten by a less wide channel type. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
