The tlv targets such as WCN3990 send more data in the chan info event, which is
not sent by the non tlv targets. There is a minimum size check in the wmi event
for non-tlv targets and hence we cannot update the common channel info
structure as it was done in commit 13104929d2 ("ath10k: fill the channel
survey results for WCN3990 correctly"). This broke channel survey results on
10.x firmware versions.
If the common channel info structure is updated, the size check for chan info
event for non-tlv targets will fail and return -EPROTO and we see the below
error messages
ath10k_pci 0000:01:00.0: failed to parse chan info event: -71
Add tlv specific channel info structure and restore the original size of the
common channel info structure to mitigate this issue.

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.

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 e8e4f5280d ("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.

Multicast/broadcast traffic destined for a particular vlan group will
always be encrypted in software. To enable dynamic VLANs, it requires
driver support for sending software encrypted packets.
In ath10k, sending software encrypted frames is allowed only when we insmod
the driver with cryptmode param set to 1, this configuration disables
hardware crypto and enables RAW mode implicitly. Since, enabling raw
mode has performance impact, this cannot be considered as an ideal
solution for supporting VLANs in the driver.
As an alternative take, in this approach, cryptographic keys for
unicast traffic (per peer PTKs) and keys for non-vlan group traffic
will be configured in hardware, allowing hardware encryption for unicast
and non-vlan group traffic. Only vlan group traffic will be encrypted in
software and pushed to the target with encap mode set to RAW in the TX
descriptors.
Not all firmwares can support this type of key configuration(having few
keys installed in hardware and few only in software); for this purpose a
new WMI service flag "WMI_SERVICE_PER_PACKET_SW_ENCRYPT" is introduced to
advertise this support.
Also, adding the logic required to send sw encrypted frames in raw mode.

Many integrated QCA9984 WiFis in various IPQ806x platform routers
from various vendors (Netgear R7800, ZyXEL NBG6817, TP-LINK C2600,
etc.) have either blank, bogus or non-unique MAC-addresses in
their calibration data.
As a result, OpenWrt utilizes a discouraged binary calibration data
patching method that allows to modify the device's MAC-addresses right
at the source. This is because the ath10k' firmware extracts the MAC
address from the supplied radio/calibration data and issues a response
to the ath10k linux driver. Which was designed to take the main MAC in
ath10k_wmi_event_ready().
Part of the "setting an alternate MAC" issue was already tackled by a
patch from Brian Norris:
commit 9d5804662c
("ath10k: retrieve MAC address from system firmware if provided")
by allowing the option to specify an alternate MAC-address with the
established device_get_mac_address() function which extracts the right
address from DeviceTree/fwnode mac-address or local-mac-address
properties and saves it for later.
However, Ben Greear noted that the Qualcomm's ath10k firmware is liable
to not properly calculate its rx-bssid mask in this case. This can cause
issues in the popluar "multiple AP with a single ath10k instance"
configurations.
To improve MAC address handling, Felix Fietkau suggested to call
pdev_set_base_macaddr_cmdid before bringing up the first vif and
use the first vif MAC address there. Which is in ath10k_core_start().
This patch implement Felix Fietkau's request to
"call pdev_set_base_macaddr_cmdid before bringing up the first vif".
The pdev_set_base_macaddr_cmdid is already declared for all devices
and version. The driver just needed the support code for this
function.

Add wmi configuration cmd to configure base band(BB) power amplifier(PA)
off timing values in hardware. The default PA off timings were fine tuned
to make proper DFS radar detection in QCA reference design. If ODM uses
different PA in their design, then the same default PA off timing values
cannot be used, it requires different settling time to detect radar pulses
very sooner and avoid radar detection problems. In that case it provides
provision to select proper PA off timing values based on the PA hardware used.
The PA component is part of FEM hardware and new device tree entry
"ext-fem-name" is used to indentify the FEM hardware. And this wmi configuration
cmd is enabled via wmi service flag "WMI_SERVICE_BB_TIMING_CONFIG_SUPPORT".
Other way is to apply these values through calibration data, but recalibration
of all boards out there might not be feasible.

Currently in 10.4 FW, all the received 4addr frames are processed for
source port learning which is enabled by default. This learning can't be
disabled by default in FW since it breaks backward compatibility.
Since ath10k uses mac80211 based 4addr mode, source port learning done in
10.4 FW is redundant and also causes issues when 3addr frames are
transmitted/received for a 4addr station.
One such visible functional impact is when GTK rekey frame from
hostapd based AP to 4addr STA is dropped in AP's 10.4 FW. This is since
GTK rekey EAPOL frame is 3addr frame on AP interface and STA enabled
with 4addr is already allowed for receiving 3addr EAPOL frames.
Source port learning implementation in 10.4 FW drops this 3addr GTK rekey
frame in AP destinated for 4addr STA causing disassociation and
re-association for every GTK rekey session. GTK rekey issue is not seen
when learning is disabled in FW.
To prevent such issues without breaking backward compatibility, FW
advertises new service bit making the source port learning configurable and
this learning is being currently disabled during ath10k vdev creation.

The host driver currently expects the channel info event to be
received in pairs for all the channels, i.e. the first
chan_info event for a particular channel will not have the
COMPLETE flag set and the second chan_info event for the
same channel will have the COMPLETE flag set.
The HL2.0 firmware sends only one channel info event per channel
which is scanned without the COMPLETE flag set. After sending the
chan_info_event for all the channels, the HL2.0 firmware sends a
chan_info_event with COMPLETE flag set to indicate the completion
of the channel info event.
The firmware does not indicate this behavior with any service bitmap
and hence a new firmware feature flag is used to handle the modified
parsing of the channel info events, in the host driver, for the
firmware which sends single channel info event per scanned channel.

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

Average ack rssi value is weighted average of ack rssi for
no of msdu's has been sent.
This feature is enabled by the host driver if firmware is capable.
After receiving event from host, firmware allocates the necessary
memory to store the ack_rssi for data packets during the init time.
After each successful transmission, If tx completion status is OK
and 24th bit is set in HTT message header then host will fetch the
ack_rssi else host can ignore the ack_rssi field.

Debugfs support to do hardware warm reset with WMI command
WMI_PDEV_PARAM_PDEV_RESET for 10.4 and 10.2.4(if wmi
service is enabled in the firmware for backward compatibility).
This change is purely for debugging purpose when hardware hangs/mutes.
This hardware reset won't affect the connectivity but there will be small
pause in data traffic. Here we are doing BB/MAC level reset and hence
whenever the BB/MAC watchdog is triggered, it does a hardware_chip_reset.
So the target will be in the active state.
Below command used to warm reset the hardware.

WCN3990 transmits management frames via WMI
with reference. Currently, with the management
tx completion not being handled, these frames are
not getting freed even after the transmission status
is returned by the firmware.
The transmitted management frames should be freed
when the firmware sends the over-the-air tx status of
the corresponding management frames.
Handle the wmi mgmt tx completion event and free
the corresponding management frame.

In the case of Station connects to AP with narrower bandwidth at beginning.
And later the AP changes the bandwidth to winder bandwidth, the AP will
beacon with wider bandwidth IE, eg VHT20->VHT40->VHT80 or VHT40->VHT80.
Since the supported BANDWIDTH will be limited by the PHYMODE, so while
Station receives the bandwidth change request, it will also need to
reconfigure the PHYMODE setting to firmware instead of just configuring
the BANDWIDTH info, otherwise it'll trigger a firmware crash with
non-support bandwidth.
The issue was observed in WLAN.RM.4.4.1-00051-QCARMSWP-1, QCA6174 with
below scenario:
AP xxx changed bandwidth, new config is 5200 MHz, width 2 (5190/0 MHz)
disconnect from AP xxx for new auth to yyy
RX ReassocResp from xxx (capab=0x1111 status=0 aid=102)

AP xxx changed bandwidth, new config is 5200 MHz, width 2 (5190/0 MHz)

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.

When trying to set wow wakeup patterns it fails with this command:
iw phyxx wowlan enable patterns offset xx+ IP address xx.xx.xx.xx
The reason is that the wow pattern from upper layer is in 802.3 format
for this case, it need to convert it to 802.11 format. The input
offset parameter is used for 802.3, but the actual offset firmware
need depends on rx_decap_mode, so that it needs to be recalculated.
Pattern of 802.3 packet is not same with 802.11 packet. If the
rx_decap_mode is ATH10K_HW_TXRX_NATIVE_WIFI, then firmware will
receive data packet with 802.11 format from hardware.

only for TLV based firmware and fix it for 10.4 firmware
as of now. The vdev stats in 10.4 firmware is split into two
parts (vdev_stats, vdev_stats_extended). The actual stats
are captured only in extended vdev stats. In order to enable
vdev stats, appropriate feature bit will be set on extended
