Hello, I notice some weird things while debugging an issue on a 4.16+ kernel with ath10k radio. It seems that the 'iw phy info' does not remove the TX-STBC info when changing the antenna mask _until_ some vdev is brought up. This makes it difficult to properly create hostapd config files. [root@lf0313-63e7 lanforge]# iw phy wiphy1 info|grep STB TX STBC RX STBC 1-stream TX STBC [root@lf0313-63e7 lanforge]# ./local/sbin/iw phy wiphy1 set antenna 1 1 [root@lf0313-63e7 lanforge]# iw phy wiphy1 info|grep STB TX STBC RX STBC 1-stream TX STBC [root@lf0313-63e7 lanforge]# iw phy wiphy1 info|grep STB TX STBC RX STBC 1-stream TX STBC [root@lf0313-63e7 lanforge]# ifconfig wlan1 up [root@lf0313-63e7 lanforge]# iw phy wiphy1 info|grep STB RX STBC 1-stream Any idea on this?
