Synchronize the ath11k backports with the current ath-next tree.
This introduces support for MBSSID and EMA, adds factory test mode and
some new HTT stats.

Subject: [PATCH] wifi: ath11k: Send HT fixed rate in WMI peer fixed param
|
|
|
|
Due to the firmware behavior with HT fixed rate setting,
|
|
HT fixed rate MCS with NSS > 1 are treated as NSS = 1
|
|
HT rates in the firmware and enables the HT fixed rate of
|
|
NSS = 1.
|
|
|
|
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.
|
