It's my own mistake while patching the patch.

Anyway, I can share my test method:

AP: (ath10k)
1. iw phy0 set antenna 1 1 (1 tx chainmask and 1 rx chainmask)
2. Use hostapd to bring up 80MHz AP

STA: (ath10k)
1. ifconfig wlan0
2. iw wlan0 connect SSID
3. echo 0x200 > /sys/module/ath10k_core/parameters/debug_mask
4. Check the "vht_nss", it should be based on your configuration of
antenna, such as vht_nss = 1 for 1 tx chainmask in AP
