Subject: ath10k: use station's current operating mode from assoc request
From: Vivek Natarajan <nataraja@xxxxxxxxxxxxxxxx>
commit 72f8cef5d1155209561b01e092ce1a04ad50c4cb upstream.
The current number of spatial streams used by the client is advertised
as a separate IE in assoc request. Use this information to set
the NSS operating mode.
Fixes: 45c9abc059fa ("ath10k: implement more versatile set_bitrate_mask").
