Currently ieee80211_csa_finish() function finalizes CSA by scheduling a
finalizing worker using the deflink. With MLO, there is a need to do it
on a given link basis.
Pass link ID of the link on which CSA needs to be finalized.

Currently, function to update beacon counter uses deflink to fetch
the beacon and then update the counter. However, with MLO, there is
a need to update the counter for the beacon in a particular link.
Add support to use link_id in order to fetch the beacon from a particular
link data during beacon update counter.

Aloka originally suggested that puncturing should be part of
the chandef, so that it's treated correctly. At the time, I
disagreed and it ended up not part of the chandef, but I've
now realized that this was wrong. Even for clients, the RX,
and perhaps more importantly, CCA configuration needs to take
puncturing into account.
Move puncturing into the chandef, and adjust all the code
accordingly. Also add a few tests for puncturing in chandef
compatibility checking.

For channel contexts, mac80211 currently uses the cfg80211
chandef struct (control channel, center freq(s), width) to
define towards drivers and internally how these behave. In
fact, there are _two_ such structs used, where the min_def
can reduce bandwidth according to the stations connected.
Unfortunately, with EHT this is longer be sufficient, at
least not for all hardware. EHT requires that non-AP STAs
that are connected to an AP with a lower bandwidth than it
(the AP) advertises (e.g. 160 MHz STA connected to 320 MHz
AP) still be able to receive downlink OFDMA and respond to
trigger frames for uplink OFDMA that specify the position
and bandwidth for the non-AP STA relative to the channel
the AP is using. Therefore, they need to be aware of this,
and at least for some hardware (e.g. Intel) this awareness
is in the hardware. As a result, use of the "same" channel
may need to be split over two channel contexts where they
differ by the AP being used.
As a first step, introduce a concept of a channel request
('chanreq') for each interface, to control the context it
requests. This step does nothing but reorganise the code,
so that later the AP's chandef can be added to the request
in order to handle the EHT case described above.

There are still surprisingly many non-chanctx drivers, but in
mac80211 that code is a bit awkward. Simplify this by having
those drivers assign 'emulated' ops, so that the mac80211 code
can be more unified between non-chanctx/chanctx drivers. This
cuts the number of places caring about it by about 15, which
are scattered across - now they're fewer and no longer in the
channel context handling.

Until now, rtl8xxxu_watchdog_callback() only fetches RSSI and updates
the rate mask in station mode. This means, in AP mode only the default
rate mask is used.
In order to have the rate mask reflect the actual connection quality,
extend rtl8xxxu_watchdog_callback() to iterate over every sta. Like in
the rtw88 driver, add a function to collect all currently present stas
and then iterate over a list of copies to ensure no RCU lock problems
for register access via USB. Remove the existing RCU lock in
rtl8xxxu_refresh_rate_mask().
Since the currently used ieee80211_ave_rssi() is only for 'vif', add
driver-level tracking of RSSI per sta.

A firmware file can contains more than one section with secure type, so
use secure information from efuse to choose the one with matched
cryptography method. Then choose key data from MSS poll (multiple security
section pool; see below picture) according to key_index from efuse.
Note that the size of MSS pool isn't included in section size defined
in firmware header, so we also need to parse header of MSS pool to get
its size as shift to parse next section.
If secure boot isn't supported by current hardware, the first secure
section will be adopted, and no need additional process to key data.

The CW1200 uses two GPIOs to control the powerup and reset
pins, get these from GPIO descriptors instead of being passed
as platform data from boardfiles.
The RESET line will need to be marked as active low as we will
let gpiolib handle the polarity inversion.
The SDIO case is a bit special since the "card" need to be
powered up before it gets detected on the SDIO bus and
properly probed. Fix this by using board-specific GPIOs
assigned to device "NULL".

endian anyway. So just remove these so they are not spamming our logs.

This is an ancient driver which has not have any meaningfuli changes for a long

sparse warnings.

After commit e3eac9f32ec0 ("wifi: cfg80211: Annotate struct
cfg80211_scan_request with __counted_by"), the compiler may enforce
dynamic array indexing of req->channels to stay below n_channels. As a
result, n_channels needs to be increased _before_ accessing the newly
added array index. Increment it first, then use "i" for the prior index.
Solves this warning in the coming GCC that has __counted_by support:
../drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c: In function 'brcmf_internal_escan_add_info':
../drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:3783:46: warning: operation on 'req->

As DSMs are going to be read from UEFI too, we need a unified API
to get DSMs for both ACPI and UEFI.
The difference in getting DSM in each one of these methods (ACPI, UEFI)
is in the GUID, revision (0 for ACPI, 4 for UEFI), and size of the DSM
values (8 or 32 for ACPI, 32 for UEFI).
Therefore, change the iwl_acpi_get_dsm_x() to iwl_acpi_get_dsm() which
determines the GUID, revision (these two are the same for all WiFi DSMs),
and size (based on a func-to-size mapping) internally.
While at it, fix DSM_FUNC_RFI_CONFIG to expect a 32-bit value
(as defined in Intel BIOS spec) and not a 8-bit one.
