We are seeing system hangs during WoWLAN suspend, and get below
two stacks:

From the first stack, ath11k_mac_drain_tx calls
cancel_work_sync(&ar->wmi_mgmt_tx_work) and waits all packets to be sent
out or dropped. However, we find from Stack2 that this work item is blocked
because ar->conf_mutex is already held by ath11k_wow_op_suspend.
Fix this issue by moving ath11k_mac_wait_tx_complete to the start of
ath11k_wow_op_suspend where ar->conf_mutex has not been acquired. And
this change also makes the logic in ath11k_wow_op_suspend match the
logic in ath11k_mac_op_start and ath11k_mac_op_stop.

There are two types of 160 MHz spectral scan support mentioned below
1. Fragmented approach
2. Single event approach
In this fragmented approach, single 160 MHz will be split as two
80 MHz buffer. First fft sample buffer will contain spectral scan
result of primary 80 MHz and the second fft sample buffer will contain
secondary 80 MHz and here cfreq1 and cfreq2 will be mentioned.
In case of 160 MHz on 36th channel will contain cfreq1 as 5210 and
cfreq2 as 5290. Chipsets which support this approach are IPQ8074/IPQ6018.
Replacing freq1 with freq2 in every secondary sepctral scan event to
distinguish between two different 80 MHz spectral event data.
In the 2nd approach each fft sample buffer will contain spectral scan
result for whole 160 MHz by mentioning cfreq1 as 5250 which is center
frequency of whole 160 MHz. Chipset which support this approach is QCN9074.
Host will receive spectral event from target for every 5 fft samples.

Add support to get the following power save information through debugfs interface,
* Current ps state of the peer
* Time duration since the peer is in power save
* Total duration of the peer spent in power save
Above information is helpful in debugging the issues with power save clients.
This patch also add trace log support for PS timekeeper to track the PS state
change of the peers alongs with the peer MAC address and timestamp.
Use the below commands to get the above power save information,
To know the time_since_station_in_power_save:
cat /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/
XX:XX:XX:XX:XX:XX/current_ps_duration
To know power_save_duration:
cat /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/
XX:XX:XX:XX:XX:XX/total_ps_duration
To reset the power_save_duration of all stations connected to AP:
echo 1 > /sys/kernel/debug/ieee80211/phyX/ath11k/reset_ps_duration
To enable/disable the ps_timekeeper:
echo Y > /sys/kernel/debug/ieee80211/phyX/ath11k/ps_timekeeper_enable
Y = 1 to enable and Y = 0 to disable.
To record PS timekeeer logs after enabling ps_timekeeper:
trace-cmd record -e ath11k_ps_timekeeper

This patch try to fix the following error.
Wed Jun 1 22:19:30 2022 kern.warn kernel: [ 119.561227] ath11k c000000.wifi: peer already added vdev id 0 req, vdev id 1 present

To repro this:
- Have 2 Wifi with the same bssid and pass on different band (2.4 and
5GHz)
- Enable 802.11r Fast Transaction with same mobility domain
- FT Protocol: FT over the Air
From a openwrt system issue the command (with the correct mac)
ubus call hostapd.wlan1 wnm_disassoc_imminent '{"addr":"28:C2:1F:xx:xx:xx"}'
Notice the log printing the errors.
The cause of this error has been investigated and we found that this is
related to the WiFi Fast Transaction feature. We observed that this is
triggered when the router tells the device to change band. In this case
the device first auth to the other band and then the disconnect path
from the prev band is triggered.
This is problematic with the current rhash implementation since the
addrs is used as key and the logic of "adding first, delete later"
conflicts with the rhash logic.
In fact peer addition will fail since the peer is already added and with
that fixed a peer deletion will cause unitended effect by removing the
peer just added.
Current solution to this is to add additional logic to the peer delete,
make sure we are deleting the correct peer taken from the rhash
table (and fallback to the peer list) and for the peer add logic delete
the peer entry for the rhash list before adding the new one (counting as
an error only when a peer with the same vlan_id is asked to be added).
With this change, a sta can correctly transition from 2.4GHz and 5GHZ
with no drop and no error are printed.

Check IEEE80211_TX_CTL_NO_CCK_RATE flag to avoid sending frames with
CCK rates in 2GHz band.
In TX flow, add IEEE80211_TX_CTL_NO_CCK_RATE flag to check and get its
lowest rate without CCK rates if the TX type is mgmt frames or data frames.
Besides, the decision of phy rate and retry rate in P2P mode are also
be handled.
In P2P GO mode, it should send beacon of no CCK rates in its frame rate.
Therefore, We add a condition to decide which rate is added to beacon
content.
Moreover, we avoid setting a mask of rates to be used for rate control
selection before and after connection in P2P mode.

The number of spatial streams used when acting as a beamformee in VHT
mode are reported by the firmware as 7 (8 sts - 1) both in IPQ6018 and
IPQ8074 which respectively have 2 and 4 sts each. So the firmware should
report 1 (2 - 1) and 3 (4 - 1).
Fix this by checking that the number of VHT beamformee sts reported by
the firmware is not greater than the number of receiving antennas - 1.
The fix is based on the same approach used in this same function for
sanitizing the number of sounding dimensions reported by the firmware.
Without this change, acting as a beamformee in VHT mode is not working
properly.

Devices may provide their own MAC address via system firmware (e.g.,
device tree), especially in the case where the device doesn't have a
useful EEPROM on which to store its MAC address (e.g., for integrated
ahb WCN6750).
Use the generic device helper to retrieve the MAC address, and (if
present) honor it above the MAC address advertised by the card.

Driver does not support get_txpower mac ops because of which
cfg80211 returns vif->bss_conf.txpower to user space. bss_conf.txpower
gets its value from ieee80211_channel->max_reg_power. However, the final
txpower is dependent on few other parameters apart from max regulatory
supported power. It is the firmware which knows about all these
parameters and considers the minimum for each packet transmission.
All ath11k firmware reports the final tx power in firmware pdev stats
which falls under fw_stats.
Add get_txpower mac ops to get the tx power from firmware leveraging
fw_stats and return it accordingly.

Currently, firmware stats, comprising pdev, vdev and beacon stats are
part of debugfs. In firmware pdev stats, firmware reports the final
Tx power used to transmit each packet. If driver wants to know the
final Tx power being used at firmware level, it can leverage from
firmware pdev stats.
Move firmware stats out of debugfs context in order to leverage
the final Tx power reported in it even when debugfs is disabled.

When running suspend test, kernel crash happened in ath10k, and it is
fixed by commit b72a4aff947b ("ath10k: skip ath10k_halt during suspend
for driver state RESTARTING").
Currently the crash is fixed, but as a common code style, it is better
to set the pointer to NULL after memory is free.
This is to address the code style and it will avoid potential bug of
use-after-free.

It has a fail log which is ath11k_dbg in ath11k_dp_rx_process_mon_status(),
as below, it will not print when debug_mask is not set ATH11K_DBG_DATA.
ath11k_dbg(ab, ATH11K_DBG_DATA,
"failed to find the peer with peer_id %d\n",
ppdu_info.peer_id);
When run scan with station disconnected, the peer_id is 0 for case
HAL_RX_MPDU_START in ath11k_hal_rx_parse_mon_status_tlv() which called
from ath11k_dp_rx_process_mon_status(), and the peer_id of ppdu_info is
reset to 0 in the while loop, so it does not match condition of the
check "if (ppdu_info->peer_id == HAL_INVALID_PEERID" in the loop, and
then the log "failed to find the peer with peer_id 0" print after the
check in the loop, it is below call stack when debug_mask is set
ATH11K_DBG_DATA.
The reason is this commit 01d2f285e3e5 ("ath11k: decode HE status tlv")
add "memset(ppdu_info, 0, sizeof(struct hal_rx_mon_ppdu_info))" in
ath11k_dp_rx_process_mon_status(), but the commit does not initialize
the peer_id to HAL_INVALID_PEERID, then lead the check mis-match.

Currently commit 1f682dc9fb37 ("ath11k: reduce the wait time of 11d scan
and hw scan while add interface") introduced a wait_for_completion_timeout
operation for ar->scan.completed, another one is existed in ath11k_scan_stop(),
then ath11k has two places to wait for the ar->scan.completed and they
run in different thread, thus it is possible to happend that the two
thread both enter wait status. To handle this scenario, ath11k should
change the complete() to complete_all() for the ar->scan.completed. This
also work well when it is only one thread wait for ar->scan.completed.

If Wi-Fi driver send Wi-Fi status to BT via scoreboard too frequent in a
short moment, BT will loss some of them because of hardware response time.
To avoid this issue, change the code flow. Summarize the scoreboard changes

a coexistence processing cycle. It also can help to reduce driver I/O.
