A major change with MLO is that cfg80211 will disable Wireless Extension (WEXT) user space interface. To avoid having inconsistent user experience, first supporting WEXT and later not, disable WEXT already now. Now ath12k claims that WEXT is not supported: $ iwconfig wlan0 wlan0 no wireless extensions.
