Issue with STBC capability and forcing radio to 1x1 mode.

[Ben Greear]

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?

Thanks,
Ben
