SAP version 4 uses larger Host to MEI notification queue.
Since it is unknown which SAP version is used by the CSME firmware
when the driver loads, try version 4 first. In case the CSME firmware
uses version 3, the memory allocation will fail. In this case the
driver will try again to allocate the memory for version 3.

The 'gl' devices are in the bz family, but they're not,
integrated, so should have their own trans config struct.
Fix that, also necessitating the removal of LTR config,
and while at it remove 0x2727 and 0x272D IDs that were
only used for test chips.

In the cases changed here, key iteration isn't done from
an RCU critical section, but rather using the wiphy lock
as protection. Therefore, just use ieee80211_iter_keys().
The link switch case can therefore also use sync commands.

Like the commit ab9177d83c04 ("wifi: mac80211: don't use rate mask for
scanning"), ignore incorrect settings to avoid no supported rate warning
reported by syzbot.
The syzbot did bisect and found cause is commit 9df66d5b9f45 ("cfg80211:
fix default HE tx bitrate mask in 2G band"), which however corrects
bitmask of HE MCS and recognizes correctly settings of empty legacy rate
plus HE MCS rate instead of returning -EINVAL.
As suggestions [1], follow the change of SCAN TX to consider this case of
offchannel TX as well.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create new tagged structures with the suffix `_hdr`.
These structures group together all the members of the original
flexible structures except the flexible arrays.
As a result, the arrays are effectively separated from the rest of the
members without modifying the memory layout of the flexible structures.
We then change the type of the middle struct members currently causing
trouble from the original flex struct to the newly created structs with
suffix `_hdr`.
We also want to ensure that when new members need to be added to the
flexible structures, they are always included within the newly created
tagged structs. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.
This approach avoids having to implement the `_hdr` structures as
completely separate structures, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
We also use `container_of()` whenever we need to retrieve a pointer to
the flexible structure, through which we can access the flexible-array
member, if necessary.
Also, remove a couple of unused zero-length arrays and flexible-array
members.
So, with these changes, fix the following warnings:

bss_config->key_mgmt specifies the AKM suites that are usable in
hardware. This variable is set to specific values while iterating
over the advertised AKM suites. This means the final value of the
variable depends on the order of the entries in the AKM suites
array. Instead of setting the variable, just set the relevant bits
in the key_mgmt bit field to make us independent of the order of
entries.
This behaviour is derived from the downstream driver that does the
same.
Also, set bss_config->key_mgmt to zero explicitly right before the
loop. bss_config has been zero allocated by the caller already, but
do so again to save the reader from following the code path.

The WPA flags setting only depends on the wpa_versions bitfield and not
on the AKM suite, so move it out of the switch/case to simplify the code
a bit. Also set bss_config->protocol to zero explicitly. This is done
only to make the code clearer, bss_config has been zero alloced by the
caller, so should be zero already. No functional change intended.

Enable USB RX aggregation when there is at least 1 Mbps RX or TX
traffic, otherwise disable it.
USB RX aggregation improves the RX speed of RTL8811CU on certain ARM
systems, like the NanoPi NEO Core2. Before: 28 Mbps, after: 231 Mbps.
It also improves the RX speed of RTL8822CU on some x86_64 systems.
Before: ~200 Mbps, after: ~300 Mbps.
The official drivers for these chips use the same logic for SDIO, but
for some reason the SDIO driver in rtw88 always enables RX aggregation,
so this patch only toggles aggregation for USB devices.
RTL8703B is likely not found in USB devices, and RTL8723DU doesn't like
aggregation.

When net-detect is enabled, WoWLAN firmware will periodically
scan until beacon or probe response of configured networks are
received. To reduce power consumption, the FW-IPS mode is
implemented to keep WiFi chip in idle mode between each scan.
The FW-IPS is controlled by WoWLAN firmware to turn of some critical
electrical components, and is different from the original IPS mode
which most electrical components are turned off.

Driver has supported different WoWLAN reason code by commit 0e5210217768
("wifi: rtw89: wow: update WoWLAN reason register for different FW")
since firmware version 0.27.80.0. The old driver can't support two
kinds of WoWLAN reason, so increase firmware format to v1.
Also driver tables of BB and RF registers and power values will be added
into v1 format.

Currently, the firmware returns incorrect pdev_id information in
WMI_PDEV_BSS_CHAN_INFO_EVENTID, leading to incorrect filling of
the pdev's survey information.
To prevent this issue, when requesting BSS channel information
through WMI_PDEV_BSS_CHAN_INFO_REQUEST_CMDID, firmware expects
pdev_id as one of the arguments in this WMI command.
Add pdev_id to the struct wmi_pdev_bss_chan_info_req_cmd and fill it
during ath12k_wmi_pdev_bss_chan_info_request(). This resolves the
issue of sending the correct pdev_id in WMI_PDEV_BSS_CHAN_INFO_EVENTID.

During PCI based hardware device start up, ASPM is disabled for all. And
once firmware is ready, it is restored back. However, not all hardwares
(for example QCN9274) supports ASPM. Hence there is a need to conditionally
restore ASPM back. Or else, for such hardwares, issue can be seen during
sending and receiving packets.
Introduce a new hardware param supports_aspm which identifies whether a
given hardware supports ASPM or not and then accordingly restore it.

We should not be checking the return values from debugfs creation at all: the
debugfs functions are designed to handle errors of previously called functions
and just transparently abort the creation of debugfs entries when debugfs is
disabled. If we check the return value and abort driver initialisation, we break
the driver if debugfs is disabled (such as when booting with debugfs=off).
Earlier versions of ath9k accidentally did the right thing by checking the
return value, but only for NULL, not for IS_ERR(). This was "fixed" by the two
commits referenced below, breaking ath9k with debugfs=off starting from the 6.6
kernel (as reported in the Bugzilla linked below).
Restore functionality by just getting rid of the return value check entirely.

If SER L2 occurs during the WoWLAN resume flow, the add interface flow
is triggered by ieee80211_reconfig(). However, due to
rtw89_wow_resume() return failure, it will cause the add interface flow
to be executed again, resulting in a double add list and causing a kernel
panic. Therefore, we have added a check to prevent double adding of the
list.

When the firmware interface layer was refactored it provided various
"get" and "set" functions. For the "get" in some cases a parameter
needed to be passed down to firmware as a key indicating what to
"get" turning the output parameter of the "get" function into an
input parameter as well. To accommodate this the "get" function blindly
copies the parameter which in some places resulted in an uninitialized
warnings from the compiler. These have been fixed by initializing the
input parameter in the past. Recently another batch of similar fixes
were submitted to address clang static checker warnings [1].
Proposing another solution by introducing a "query" variant which is used
when the (input) parameter is needed by firmware. The "get" variant will
only fill the (output) parameter with the result received from firmware
taking care of proper endianess conversion.

In the "struct brcmf_ampdu_rx_reorder", change the 'pktslots' field into
flexible array.
It saves the size of a pointer when the memory is allocated and avoids
an indirection when the array is used.
It also removes the usage of a pointer arithmetic and saves a few lines of
code.
Finally, struct_size() can be used. It is not a must have here, because
it is easy to see that buf_size can not overflow, but still, it is a good
practice.
