We have some policy via BIOS to block uses of 6 GHz. In this case, 6 GHz
sband will be NULL even if it is WiFi 7 chip. So, add NULL handling here
to avoid crash.

firmware command
The DMA channel of firmware command doesn't use TX WD (WiFi descriptor), so
don't need to consider number of TX WD as factor of TX resource. Otherwise,
during pause state (a transient state to switch to/from low power mode)
firmware commands could be dropped and driver throws warnings suddenly:
rtw89_8852ce 0000:04:00.0: no tx fwcmd resource
rtw89_8852ce 0000:04:00.0: failed to send h2c
The case we met is that driver sends RSSI strength of firmware command at
RX path that could be running concurrently with switching low power mode.
The missing of this firmware command doesn't affect user experiences,
because the RSSI strength will be updated again after a while.
The DMA descriptors of normal packets has three layers like:
+-------+
| TX BD | (*n elements)
+-------+
|
| +-------+
+-> | TX WD | (*m elements)
+-------+
|
| +--------+
+-> | SKB |
+--------+
And, firmware command queue (TXCH 12) is a special queue that has only
two layers:
+-------+
| TX BD | (*n elements)
+-------+
|
| +------------------+
+-> | firmware command |

This function is supposed to return a uid on success, and an errno in
failure.
But it currently returns the return value of the specific cmd version
handler, which in turn returns 0 on success and errno otherwise.
This means that on success, iwl_mvm_build_scan_cmd will return 0
regardless if the actual uid.
Fix this by returning the uid if the handler succeeded.

Every time EHT Operation element changed, mac80211 will parse it and
extract the valid puncturing bitmap according to the bandwidth.
Current driver only update puncturing bitmap to firmware as vdev
parameter. Which can only meet the needs of AP. But STA will also use
it as peer parameter. If only update as vdev parameter, might cause
firmware crash. QCN9274 is the same.
So update bandwidth and puncturing bitmap as peer parameters once they
changed for STA. Then send them to the firmware by WMI event.

Currently, in the rx error data path, mac id is extracted from the
last 64bits of MSDU end description tag for each entry received in
the WBM error ring. Then, each entry will be updated into the MSDU
list for further processing. The extracted mac id is valid when a
single MSDU is not fragmented and received in the WBM error ring.
In scenarios where the size of a single MSDU received exceeds the
descriptor buffer size, resulting in fragmented or spillover MSDU
entries into the WBM error ring. In this case, the extracted mac id
from each spillover entry is invalid except the last spillover entry
of the MSDU. This invalid mac id leads to packet rejection.
To address this issue, check if the MSDU continuation flag is set,
then extract the valid mac id from the last spillover entry.
Propagate the valid mac id to all the spillover entries of the single
MSDU in the temporary MSDU list(scatter_msdu_list). Then, update this
into the MSDU list (msdu_list) for further processing.

As multiple radios are combined into a single wiphy, and
the current infrastructure supports only set/get antenna
for the wiphy, the max Tx/Rx antenna capability is advertised
during wiphy register.
Hence, When antenna set/get is received we adjust the set/get
based on max radio capability and set/get antenna accordingly.
Multi radio capability needs to introduced with interface
combination changes to support single wiphy model in cfg80211
which would help extend the wiphy specific get/set configs similar

not be updated to cfg80211. Rather we can pick one of the regd
built from the rules to update to cfg80211 for the whole
registered device. We prefer 6 GHz pdev based rules since it has
the rules for all bands. If the hw doesn't support 6 GHz, then update
rules from one of the pdevs.
Also, when regulatory notification is received, update to all the
underlying radios/ar so that it becomes aware of the change and as
well us it updates its local regd with the new country rules. Later
pick the appropriate pdev's regd(6 GHz if available) and apply to
cfg80211.

When multiple radios are advertised as a single wiphy which
supports various bands, a default scan request to mac80211
from cfg80211 will split the driver request based on band,
so each request will have channels belonging to the same band.
With this supported by default, the ath12k driver on receiving
this request checks for one of the channels in the request and
selects the corresponding radio(ar) on which the scan is going
to be performed and creates a vdev on that radio.
Note that on scan completion this vdev is not deleted. If a new
scan request is seen on that same vif for a different band the
vdev will be deleted and created on the new radio supporting the
request. The vdev delete logic is refactored to have this done
dynamically.
The reason for not deleting the vdev on scan stop is to avoid
repeated delete-create sequence if the scan is on the same band.
Also, during channel assign, new vdev creation can be optimized
as well.
Also if the scan is requested when the vdev is in started state,
no switching to new radio is allowed and scan on channels only
within same radio is allowed.

With single wiphy, multiple radios are combined into a single wiphy.
Since any channel can be assigned to a vif being brought up,
the vdev cannot be created during add_interface(). Hence defer the
vdev creation till channel assignment.
If only one radio is part of the wiphy, then the existing logic
is maintained, i.e vdevs are created during add interface and
started during channel assignment. This ensures no functional changes
to single pdev devices which has only one radio in the SoC.

Now that all infrastructure is in place and ath11k is fixed to handle all the
corner cases, power down the ath11k firmware during suspend and power it back
up during resume. This fixes the problem when using hibernation with ath11k PCI
devices.
For suspend, two conditions needs to be satisfied:
1. since MHI channel unprepare would be done in late suspend stage,
ath11k needs to get all QMI-dependent things done before that stage.
2. and because unprepare MHI channels requires a working MHI stack,
ath11k is not allowed to call mhi_power_down() until that finishes.
So the original suspend callback is separated into two parts: the first part
handles all QMI-dependent things in suspend callback; while the second part
powers down MHI in suspend_late callback. This is valid because kernel calls
ath11k's suspend callback before all suspend_late callbacks, making the first
condition happy. And because MHI devices are children of ath11k device
(ab->dev), kernel guarantees that ath11k's suspend_late callback is called
after QRTR's suspend_late callback, this satisfies the second condition.
Above analysis also applies to resume process. so the original resume
callback is separated into two parts: the first part powers up MHI stack
in resume_early callback, this guarantees MHI stack is working when
QRTR tries to prepare MHI channels (kernel calls QRTR's resume_early callback
after ath11k's resume_early callback, due to the child-father relationship);
the second part waits for the completion of restart, which won't fail now
since MHI channels are ready for use by QMI.
Another notable change is in power down path, we tell mhi_power_down() to not
to destroy MHI devices, making it possible for QRTR to help unprepare/prepare
MHI channels, and finally get us rid of the probe-defer issue when resume.
Also change related code due to interface changes.

Different Qualcomm platforms using WCN3990 WiFI chip use SoC-specific
firmware versions with different features. For example firmware for
SDM845 doesn't use single-chan-info-per-channel feature, while firmware
for QRB2210 / QRB4210 requires that feature. Allow board DT files to
override the subdir of the fw dir used to lookup the firmware-N.bin file
decribing corresponding WiFi firmware.
For example:
- ath10k/WCN3990/hw1.0/wlanmdsp.mbn,
ath10k/WCN3990/hw1.0/firmware-5.bin: main firmware files, used by default
- ath10k/WCN3990/hw1.0/qcm2290/wlanmdsp.mbn,
ath10k/WCN3990/hw1.0/qcm2290/firmware-5.bin: SoC specific firmware
with different signature and feature bits
Note, while board files lookup uses the same function and thus it is
possible to provide board-specific board-2.bin files, this is not
required in 99% of cases as board-2.bin already contains a way to
provide board-specific data with finer granularity than DT overrides.

This driver's initialization functions do not perform any custom code,
except printing messages. Printing messages on modules
loading/unloading is discouraged because it pollutes the dmesg
regardless whether user actually has this device. Core kernel code
already gives tools to investigate whether module was loaded or not.
Drop the printing messages which allows to replace open-coded
module_sdio_driver().

and avoid -Wfamnae warning
Prepare for the coming implementation by GCC and Clang of the
__counted_by attribute. Flexible array members annotated with
__counted_by can have their accesses bounds-checked at run-time
via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE
(for strcpy/memcpy-family functions).
Also, -Wflex-array-member-not-at-end is coming in GCC-14, and we are
getting ready to enable it globally.
So, use the `DEFINE_FLEX()` helper for an on-stack definition of
a flexible structure where the size of the flexible-array member
is known at compile-time, and refactor the rest of the code,
accordingly.
So, with these changes, fix the following warning:
drivers/net/wireless/ath/wil6210/wmi.c:4018:49: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

gcc-9 and some other older versions produce a false-positive warning
for zeroing two fields
In file included from include/linux/string.h:369,
from drivers/net/wireless/ath/ath9k/main.c:18:
In function 'fortify_memset_chk',
inlined from 'ath9k_ps_wakeup' at drivers/net/wireless/ath/ath9k/main.c:140:3:
include/linux/fortify-string.h:462:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
462 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Using a struct_group seems to reliably avoid the warning and
not make the code much uglier. The combined memset() should even
save a couple of cpu cycles.

The carl9170_tx_release() function sometimes triggers a fortified-memset
warning in my randconfig builds:
In file included from include/linux/string.h:254,
from drivers/net/wireless/ath/carl9170/tx.c:40:
In function 'fortify_memset_chk',
inlined from 'carl9170_tx_release' at drivers/net/wireless/ath/carl9170/tx.c:283:2,

493 | __write_overflow_field(p_size_field, size);
Kees previously tried to avoid this by using memset_after(), but it seems
this does not fully address the problem. I noticed that the memset_after()
here is done on a different part of the union (status) than the original
cast was from (rate_driver_data), which may confuse the compiler.
Unfortunately, the memset_after() trick does not work on driver_rates[]
because that is part of an anonymous struct, and I could not get
struct_group() to do this either. Using two separate memset() calls
on the two members does address the warning though.
