The wmi service available event has been
extended to contain extra 128 bit for new services
to be indicated by firmware.
Currently the presence of any optional TLVs in
the wmi service available event leads to a parsing
error with the below error message:
ath10k_snoc 18800000.wifi: failed to parse svc_avail tlv: -71
The wmi service available event parsing should
not return error for the newly added optional TLV.
Fix this parsing for service available event message.

This target IRAM recovery feature support is to copy target
IRAM contents available at ATH10K_MEM_REGION_TYPE_REG to host
memory for back up after firmware loaded. Target IRAM contents
are copied to wmi memory chunks allocated for the
WMI_IRAM_RECOVERY_HOST_MEM_REQ_ID and provide the wmi chunks
address to the firmware through wmi init command.
If firmware detects andy IRAM corruption through periodic
checksum validation, It will download the IRAM contents back
from the provided wmi memory chunks address using hif_memcpy.
This IRAM recovery feature prevent target assert in case of
unexpected target IRAM corruptions.
This patch also introduce a new feature flag 'iram-recovery' for
backward compatibility.

This patch add ops for set_tid_config to support TID
specific configuration. Station specific TID configuration
will have more priority than vif specific TID configuration.
WMI_SERVICE_PEER_TID_CONFIGS_SUPPORT service flag introduced
to notify host for TID config support. And RTS_CTS extended tid
configuration support advertised through the service flag
WMI_10_4_SERVICE_EXT_PEER_TID_CONFIGS_SUPPORT.
TID specific noack configuration requires
aggregation should be disabled and rate for the data TID packets
should be basic rates. So, if the TID already configured
with noack policy then driver will ignore the aggregation
or TX rate related configuration for the same data TID.
In TX rate configuration should be applied with highest
preamble configuration(HT rates should not be applied
for the station which supports vht rates).

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

For SDIO chip, its rx indication is struct htt_rx_indication_hl, which
does not include the bitrate info as well as PCIe, for PCIe, it use
function ath10k_htt_rx_h_rates to parse the bitrate info in struct
rx_ppdu_start and then report it to mac80211 via ieee80211_rx_status.
SDIO does not have the same info as PCIe, then iw command can not get

When hardware rfkill is enabled in the firmware it will report the
capability via using WMI_TLV_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY
event to the host. ath10k will check the capability, and if it is enabled then
ath10k will set the GPIO information to firmware using WMI_PDEV_SET_PARAM. When
the firmware detects hardware rfkill is enabled by the user, it will report it
via WMI_RFKILL_STATE_CHANGE_EVENTID. Once ath10k receives the event it will
send wmi command WMI_PDEV_SET_PARAM to the firmware to enable/disable the radio
and also notifies cfg80211.
We can't power off the device when rfkill is enabled, as otherwise the
firmware would not be able to detect GPIO changes and report them to the
host. So when rfkill is enabled, we need to keep the firmware running.

Currently, below fixed rate commands are broken,

<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.

In WCN3990, WMI_TLV_SERVICE_TX_DATA_MGMT_ACK_RSSI service Indicates that
the firmware has the capability to send the RSSI value of the ACK for all
data and management packets transmitted.
If WMI_RSRC_CFG_FLAG_TX_ACK_RSSI is set in host capability then firmware
sends RSSI value in "management" tx completion event. Host extracts ack
rssi values of management packets from their tx completion event.

When adding a new value to enum wmi_service it's very easy to miss that the new
value should be also added to wmi_service_name() mapping function. Modify the
function so that GCC can now warn about this:
drivers/net/wireless/ath/ath10k/wmi.h:385:2: warning: enumeration value 'WMI_SERVICE_FOO' not handled in switch [-Wswitch]
And also add a reminder to the enum.

If supported, update transmit airtime in mac80211 with the airtime
values reported by the firmware. TX airtime of the PPDU is reported
via HTT data TX completion indication message.
A new service flag 'WMI_SERVICE_REPORT_AIRTIME' is added to advertise
the firmware support. For firmwares which do not support this feature,
TX airtime is calculated in the driver using TX bitrate.

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 9d5804662ce1
("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.
This change tested on firmware ver 10.2.4-1.0-00042 in QCA988X chipset.

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.

Mesh path metric needs tx rate information from ieee80211_tx_status()
call but in ath10k there is no mechanism to report tx rate information
via ieee80211_tx_status(), the tx rate is only accessible via

to ath10k driver after every 4 PPDU sent in the air. For each PPDU,
ath10k driver updates rate informattion to mac80211 using

HL2.0 firmware does not support setting quiet mode. If the host driver sends
the quiet mode setting command to the HL2.0 firmware, it crashes with the below
signature.

The quiet mode command support is exposed by the firmware via thermal throttle
wmi service. Enable ath10k thermal support if thermal throttle wmi service bit
is set. 10.x firmware versions support this feature by default, but
unfortunately do not advertise the support via service flags, hence have to
manually set the service flag in ath10k_core_compat_services().

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.
