As clang points out, the vht_pfr is assigned to a struct member

ath10k will receive some message with invalid peer id from firmware.
reason is:
There are incoming frames to MAC hardware that NOT find relative
address search table, then peer id is invalid set by MAC hardware,
it is hardware's logic, so fix it in ath10k will be more convenient.

This change fixes a rare race condition of handling WMI events after
wmi_call expires.
wmi_recv_cmd immediately handles an event when reply_buf is defined and
a wmi_call is waiting for the event.
However, in case the wmi_call has already timed-out, there will be no
waiting/running wmi_call and the event will be queued in WMI queue and
will be handled later in wmi_event_handle.
Meanwhile, a new similar wmi_call for the same command and event may
be issued. In this case, when handling the queued event we got WARN_ON
printed.
Fixing this case as a valid timeout and drop the unexpected event.

RBUFCAP support added in FW.
The RBUFCAP feature is amendment to the block ack mechanism to
prevent overloading of the recipient’s memory space, which may
happen in case the link speed is higher than STA’s capability
to process or consume incoming data.
The block ack policy (ba_policy) is now controlled by FW so driver
should ignore this field.

This patch removes the error branch for (queue > ar->hw->queues).
It is no longer needed anymore as the "queue" value is validated by
cfg80211's parse_txq_params() before the driver code gets called.
Some background:
In the old days (linux 2.6 and early 3.x), the parse_txq_params()
function did not verify the "queue" value. That's why these drivers
had to do it.

This patch follows Alan Stern's recent patch:
"p54: Fix race between disconnect and firmware loading"
that overhauled carl9170 buggy firmware loading and driver
unbinding procedures.
Since the carl9170 code was adapted from p54 it uses the
same functions and is likely to have the same problem, but
it's just that the syzbot hasn't reproduce them (yet).
a summary from the changes (copied from the p54 patch):
* Call usb_driver_release_interface() rather than
device_release_driver().
* Lock udev (the interface's parent) before unbinding the
driver instead of locking udev->parent.
* During the firmware loading process, take a reference
to the USB interface instead of the USB device.
* Don't take an unnecessary reference to the device during
probe (and then don't drop it during disconnect).
and
* Make sure to prevent use-after-free bugs by explicitly
setting the driver context to NULL after signaling the
completion.

In commit 3c0efb745a17 ("ath9k: discard undersized packets")
the lower bound of RX packets was set to 10 (min ACK size) to
filter those that would otherwise be treated as invalid at
mac80211.
Alas, short radar pulses are reported as PHY_ERROR frames
with length set to 3. Therefore their detection stopped
working after that commit.
NOTE: ath9k drivers built thereafter will not pass DFS
certification.
This extends the criteria for short packets to explicitly
handle PHY_ERROR frames.

This patch will add the support to control the transmit power for traffic
to a station associated with the AP.
Underlying firmware will enforce that the maximum tx power will be based
on the regulatory requirements. If the user given transmit power is greater
than the allowed tx power in the given channel, then the firmware will use
the maximum tx power in the same channel.
Max and Min tx power values will depends on no of tx chain masks,
for QCA9984 allowed tx power range values from 6 to 23.
When 0 is sent to the firmware as tx power, it will revert to the default
tx power for the station.

Observed PCIE device wake up failed after ~120 iterations of
soft-reboot test. The error message is
"ath10k_pci 0000:01:00.0: failed to wake up device : -110"
The call trace as below:
ath10k_pci_probe -> ath10k_pci_force_wake -> ath10k_pci_wake_wait ->
ath10k_pci_is_awake
Once trigger the device to wake up, we will continuously check the RTC
state until it returns RTC_STATE_V_ON or timeout.
But for QCA99x0 chips, we use wrong value for RTC_STATE_V_ON.
Occasionally, we get 0x7 on the fist read, we thought as a failure
case, but actually is the right value, also verified with the spec.
So fix the issue by changing RTC_STATE_V_ON from 0x5 to 0x7, passed
~2000 iterations.

Currently, below fixed rate commands are broken,
iw wlanx set bitrates legacy-<2.4|5> ht-mcs-<2.4|5> vht-mcs-<2.4|5> \
<NSS:MCSx>
iw wlanx set bitrates legacy-<2.4|5> <legacy rate> ht-mcs-<2.4|5> \
vht-mcs-<2.4|5> <NSS:MCSx>
There are two methods to set fixed rate, both failed,
- Use vdev fixed rate command
This command only support one single rate, but it's broken due to
mac80211 change commit e8e4f5280ddd ("mac80211: reject/clear user
rate mask if not usable"), which requires user to specify at least
one legacy rate. So we can't use this command to set ht/vht single
rate any more.
- Use peer_assoc command
This command can update rx capability for multiple rates, it will
work fine for ht mcs rates, as each supported mcs can be advertised
in ht_mcs index mask. But this will not work with vht rates because,
as per the vht mcs capability advertisement, there are only two bits
to indicate the supported mcs. E.g. only support 0-7, 0-8, 0-9.
So introduced new WMI command: WMI_PEER_PARAM_FIXED_RATE. After peer
assoc, the peer fixed rate cmd will work for that specific peer.
Remaining peers will use auto rate. If both vdev fixed rate and peer
fixed rates are given, peer fixed rate will take effect to peers for
which this cmd is given. Remaining peers in that vdev, will use vdev
fixed rate.

For QCA988X target, pktlog gives details of the tx bitrate
which is used in the driver for station info.
Enabling pktlog by default will cause more interrupts
in target to host CE pipe, which can impact more CPU usage
for targets ex:WCN3990 and also not required for all other
platforms (eg: WCN3990), for getting tx bitrate.
Enable pktlog only for QCA988X based on hardware params.

Lockdep warns at lockdep_assert_held(&ar->data_lock) in
ath10k_htt_rx_pn_check_replay_hl(). Acquire ar->data_lock before calling
ath10k_htt_rx_pn_check_replay_hl() to fix it.
Call trace:

Firmware name for UTF mode of SDIO has changed from utf-2.bin to
utf-sdio-2.bin, so it need to change in ath10k, otherwise it will
fail for UTF mode.
After change the name in ath10k, it will success for UTF mode of
SDIO/USB.
Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00007-QCARMSWP-1.

The command to simulate firmware crash:
echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash
It will send WMI_FORCE_FW_HANG_ASSERT to firmware, then it will trigger
CPU interrupt status register for SDIO chip, ath10k driver need to
configure it while enable SDIO interrupt, otherwise ath10k driver will
not get the assert error info.
After this change, it will success for simulate firmware crash.

ath10k_dbg() is called in ath10k_process_rx() with huge set of arguments
which is causing CPU overhead even when debug_mask is not set.
Good improvement was observed in the receive side performance when call
to ath10k_dbg() is avoided in the RX path.
Since currently all debug messages are sent via tracing infrastructure,
we cannot entirely avoid calling ath10k_dbg. Therefore, call to
ath10k_dbg() is made conditional based on tracing config in the driver.
Trasmit performance remains unchanged with this patch; below are some
experimental results with this patch and tracing disabled.

This is done in order to make the *htt_h2t_aggr_cfg_msg* op align better
with the rest of the htt ops (whom all have inline wrappers).
It also adds support for the case when the op is missing (function
pointer is NULL).
As a result of this, the name of the 32 bit implementation in htt_tx.c
was changed and the function was made static.

Honestly all the conflicts were simple overlapping changes,

ifa_list is protected by rcu, yet code doesn't reflect this.
Add the __rcu annotations and fix up all places that are now reported by
sparse.
I've done this in the same commit to not add intermediate patches that
result in new warnings.
