Add WCN3990 QMI client handshakes for Q6 integrated WLAN connectivity
subsystem. This layer is responsible for communicating qmi control
messages to wifi fw QMI service using QMI messaging protocol.
Qualcomm MSM Interface(QMI) is a messaging format used to communicate
between components running between remote processors with underlying
transport layer based on integrated chipset(shared memory) or
discrete chipset(PCI/USB/SDIO/UART).

For WoWLAN support it is expected to support wake up based on discovery of
one or more known SSIDs. This is the WIPHY_WOWLAN_NET_DETECT feature,
which shows up as an NL80211 feature flag.
This shows up in 'iw phy' as:
WoWLAN support:
* wake up on network detection, up to 16 match sets
And it can be enabled with command:
iw phy0 wowlan enable net-detect interval 5000 delay 30 freqs 2412 matches ssid foo
Firmware will do scan by the configured parameters after suspend and
wakeup if it found matched SSIDs. Tested with QCA6174 hw3.0 with
firmware WLAN.RM.4.4.1-00110-QCARMSWPZ-1.

This patch helps to get the power save state change of each peer
connected to the AP. With WMI_10_4_PEER_STA_PS_STATECHG_EVENTID
event, ps state of each peer is reported to user space via
debugfs.
Use the below command to get the ps state of each sta:
cat /sys/kernel/debug/ieee80211/phyX/netdev::wlanX/stations/
XX:XX:XX:XX:XX:XX/peer_ps_state
If STA is in power save state, we get the peer_ps_state value as 1.
if STA is not in power save state, we get the peer_ps_state value as 0.
If ps_state event is disabled, we get the peer_ps_state value as 2.
We can enable/disable the ps_state events using the debugfs flag
"ps_state_enable"
echo Y > /sys/kernel/debug/ieee80211/phyX/ath10k/ps_state_enable
Y = 1 to enable and Y = 0 to disable

To support dual-band variant of QCA9984, new extended board data (eBDF)
is introduced since existing board data ran out of space.
Below is the brief implementation & design detail,
----------------------------------------------------
1. New OTP changes to inform eBDF support in existing OTP download to
fetch board ID and chip ID. This is backward compatible and older
card sends 0 by default for eBDF support bit (bit 18 of OTP response) we
check in ath10k driver.
2. If eBDF is supported, then we need to fetch eBDF ID which is bundled
in downloaded board data. So again OTP is executed for knowing the eBDF ID.
This is done once we set 'board_data_initialized' bit. If eBDF ID
returned is zero, we continue booting with previous board data downloaded.
3. Based on the eBDF ID fetched, ath10k driver tries to download the
extended board data to a new offset ahead of already downloaded board
data address.
4. A new BD IE type, ATH10K_BD_IE_BOARD_EXT is added to differentiate in
bundling eBDF separately in board-2.bin and also to parse through
board bundle for eBDF download in ath10k boot.
5. If eBDF is not present in the board-2.bin bundle or when board ID is
zero, we do a fallback boot to "eboard.bin" in the same QCA9984/hw1.0 dir.
This is same as done to existing "board.bin" if board ID is not present
in board-2.bin bundle.
Current design is that eBDF size will be 2KB and eBDF ID will be
byte value.
Tested the above changes with dual-band variant of QCA9984 card. OTP
update needed for the test will be part of next FW release 10.4-3.6-xxxx.
Below are the logs with ath10k BOOT debugs enabled.

In the 10.4-3.6 firmware branch there's a new DFS Host confirmation
feature which is advertised using WMI_SERVICE_HOST_DFS_CHECK_SUPPORT flag.
This new features enables the ath10k host to send information to the
firmware on the specifications of detected radar type. This allows the
firmware to validate if the host's radar pattern detector unit is
operational and check if the radar information shared by host matches
the radar pulses sent as phy error events from firmware. If the check
fails the firmware won't allow use of DFS channels on AP mode when using
FCC regulatory region.
Hence this patch is mandatory when using a firmware from 10.4-3.6 branch.
Else, DFS channels on FCC regions cannot be used.

Add memory dump to the firmware crash data file which is provided to user space
via devcoredump interface. This makes it easier for firmware engineers to debug
firmware crashes.
Due to increased memory consumption the memory dump is disabled by default. To
enable it make sure that bit 3 is set in coredump_mask module parameter:
modprobe ath10k_core coredump_mask=0xffffffff
When RAMDUMP is enabled a buffer for the dump is allocated with vmalloc during
device probe. The actual memory layout is different in hardware versions and
the layouts are defined in coredump.c. The memory is split to regions and, to
get even finegrained control of what to copy, the region can split to smaller
sections as not all registers are readable (which could cause the whole system
to stall).

With current NAPI implementation, NAPI poll can deliver more frames

Remaining quota is not accounted, while processing amsdus in

prevent delivering more frames to net core. With this change,
all amdus from both in_ord_ind and rx_ind queues are processed and
enqueued into common skb list instead of delivering into mac80211.
Later msdus from common queue are dequeued and delivered depends on

If a 5 GHz radio is calibrated for operation in both
the low band (channels 36 to 64) and high band(channels 100 to 169),
hardware allows operations in all the listed channels. However,
if the chip has been calibrated only for the low/high band and
a high/low band channel is configured, due to lack of calibration
there will be potentially invalid signal on those non calibrated channels.
To avoid this problem this patch sets IEEE80211_CHAN_DISABLED flag for
those non calibrated channels by using low_5ghz_chan and high_5ghz_chan
values which we get from target through wmi service ready event.
Driver initialized flags are getting re initialized in handle_channel

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified, among others, by device and sybsystem ids.
The problem, however, can occur when the (default) board data file cannot
fulfill with the vendor requirements and it is necessary to use a different
board data file.
To solve the issue QCA uses SMBIOS type 0xF8 to store Board Data File Name
Extension to specify the extension/variant name. The driver will take the
extension suffix into consideration and will load the right (non-default)
board data file if necessary.
If it is unnecessary to use extension board data file, please leave the
SMBIOS field blank and default configuration will be used.
Example:
If a default board data file for a specific board is identified by a string
"bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
subsystem-device=0310"
then the OEM specific data file, if used, could be identified by variant
suffix:
"bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
subsystem-device=0310,variant=DE_1AB"
If board data file name extension is set but board-2.bin does not contain
board data file for the variant, the driver will fallback to the default
board data file not to break backward compatibility.
This was first applied in commit f2593cb1b291 ("ath10k: Search SMBIOS for OEM
board file extension") but later reverted in commit 005c3490e9db ("Revert
"ath10k: Search SMBIOS for OEM board file extension"". This patch is now
otherwise the same as commit f2593cb1b291 except the regression fixed.

This reverts commit f2593cb1b29185d38db706cbcbe22ed538720ae1.
Paul reported that this patch with older board-2.bin ath10k initialisation
fails on Dell XPS 13:
ath10k_pci 0000:3a:00.0: failed to fetch board data for bus=pci,vendor=168c,
device=003e,subsystem-vendor=1a56,subsystem-device=1535,variant=RV_0520 from
ath10k/QCA6174/hw3.0/board-2.bin
The reason is that the older board-2.bin does not have the variant version of
the image name and ath10k does not fallback to the older naming scheme.

Station pointers are RCU protected so driver must
be extra careful if it tries to store them
internally for later use outside of the RCU
section it obtained it in.
It was possible for station teardown to race with
some htt events. The possible outcome could be a
use-after-free and a crash.
Only peer-flow-control capable firmware was
affected (so hardware-wise qca99x0 and qca4019).
This could be done in sta_state() itself via
explicit synchronize_net() call but there's
already a convenient sta_pre_rcu_remove() op that
can be hooked up to avoid extra rcu stall.
The peer->sta pointer itself can't be set to
NULL/ERR_PTR because it is later used in
sta_state() for extra sanity checks.

In order to receive other BSS entries in mesh mode, Monitor vdev
is created whenever filter flag is set with OTHER_BSS. Recently
it is root caused that setting promisc filter for Mesh interface
is causing performance and stability issues. To fix this issue,
firmware will configure appropriate rxfilters by default for mesh
vdev during vdev creation. This change fixes monitor vdev creation
based on firmware IE

Per peer tx stats are part of 'HTT_10_4_T2H_MSG_TYPE_PEER_STATS'
event, Firmware sends one HTT event for every four PPDUs.
HTT payload has success pkts/bytes, failed pkts/bytes, retry
pkts/bytes and rate info per ppdu.
Peer stats are enabled through 'WMI_SERVICE_PEER_STATS',
which are nowadays enabled by default.
Parse peer stats and update the tx rate information per STA.
