+Subject: hostapd: prevent channel switch for 5GHz
+
+hostapd would switch the primary and secondary channel on 5GHz networks in
+certain circumstances, completely breaking the adhoc interfaces of the WLAN
+adapter (they would lose their configuration).
+
+As a temporary fix, disable this channel switch function.
