This leads to HT fixed rate is always configured for NSS = 1 even though the user sets NSS = 2 or > 1 HT fixed MCS in the set bitrate command. Currently HT fixed MCS is sent via WMI peer assoc command. Fix this issue, by sending the HT fixed rate MCS in WMI peer fixed param instead of sending in peer assoc command.
