Subject: ath10k: set peer MFP flag in peer assoc command

Set peer's management frame protection flag in peer assoc command,
this setting will enable/disable encrytion of management frames in fw.

Setting of this flag is based on whether MFP is enabled/disabled at STA
and a firmware feature flag ATH10K_FW_FEATURE_MFP_SUPPORT. This is because
only firmwares 10.1.561 and above have support for MFP.

Subject: ath10k: debugfs file to enable Bluetooth coexistence feature

As not all QCA98XX radios are not connected to Bluetooth modules, enabling the
BT coex feature in firmware will have side effects if the radio's GPIO are
connected with other (non-BT) HW modules. Add debugfs file to control the
firmware BT coex logic and set the feature as disable by default to avoid that
btcoex is accidentally enabled.

To enable this feature, execute:

echo 1 > /sys/kernel/debug/ieee80211/phyX/ath10k/btcoex

To disable:

echo 0 > /sys/kernel/debug/ieee80211/phyX/ath10k/btcoex

The firmware support this feature since 10.2.4.54 on 2G-only board, dual band
or 5G boards don't support this. The feature's name is WMI_SERVICE_COEX_GPIO
and the btcoex file is not created if firmware doesn't support it.

Subject: ath10k: fix peer assoc complete WMI command for 10.4

There is an extra 4-byte member when compared to WMI 10.2 added to
assoc complete command in WMI 10.4. This new member is used for 160Mhz
related configuration. This WMI command mismatch between host and
firmware does not cause any real issues because this new member is not
used in 10.4 firmwares so far (10.4.1.00030-1). This difference in WMI
command interface brings in a new wmi_ops for 10.4 gen_peer_assoc().
No noticeable functionality differences with this change can be seen
with the current 10.4 firmwares, but the WMI interface has to be
fixed to work with future 10.4 firmwares which may be using this new
member.

Subject: ath10k: fix peerid configuration in htt tx desc for htt version < 3.4

Of a word in struct htt_data_tx_desc htt version >= 3.4 firmware uses
LSB 16-bit for frequency configuration which is used for offchannel tx
and MSB 16-bit is for peerid. But other firmwares using version 2.X
(10.1, 10.2.2, 10.2.4 and 10.4) are using 32-bit for peerid in htt tx
desc. So far no issue is found with the existing code setting peerid and
freq for HTT version 2.X, this could be mainly because of 0 as frequecy
(home channel) is being always passed with those firmwares. There may be
issues when non-zero freq is passed with firmware using < 3.4 htt version.
To be safe use target_version_major and target_version_minor along with
htt-op-version before configuring peer id and freq in htt tx desc. This
patch extends ath10k_mac_tx_frm_has_freq() to check for htt_op_version_tlv
and uses the helper while setting peerid in htt_tx_desc.

Subject: ath10k: fix the wrong RX rate idx report at 11G mode

The RX rate idx is not correct for 11G mode OFDM packet.
Because the bitrate table start with CCK index instead of OFDM.

Subject: wil6210: hold wil->mutex while managing vrings

To prevent race when connect flow may run in parallel with
the disconnect event.

Scenario leading to the bug is: while running connect flow on the AP,
STA sends disconnect. log follows.
