struct net_device shouldn't be embedded into any structure, instead,
the owner should use the priv space to embed their state into net_device.
Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].
Un-embed the net_device from struct iwl_trans_pcie by converting it
into a pointer. Then use the leverage alloc_netdev() to allocate the
net_device object at iwl_trans_pcie_alloc.
The private data of net_device becomes a pointer for the struct
iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent
given the net_device object.

The deadlock happens on my system with 24 iwlwifi radios, so maybe
it something like all worker threads are busy and some work that needs

On older (pre-MLD API) devices, we started also calling
iwl_mvm_set_link_mapping()/iwl_mvm_unset_link_mapping(),
but of course not also iwl_mvm_remove_link(). Since the
link ID was only released in iwl_mvm_remove_link() this
causes us to run out of FW link IDs very quickly. Fix
it by releasing the link ID correctly.

- From debugfs, for testing purposes.

Address scenarios where repeated entry and exit from EMLSR occur, such as
encountering missed beacons on a specific link,
while still discovering that link during a scan.
To mitigate this, introduce the EMLSR prevention mechanism, which operates
as follows:
- On each exit from EMLSR event, record the timestamp and the exit
reason.
- If two consecutive exits happen for the same reason within a
400-second window, enforce a 300-second EMLSR prevention.
- If a third exit for the same reason occurs within 400 seconds from the
second exit, enforce an extended EMLSR prevention of 600 seconds.

completely, and there are reasons for which we need to block EMLSR.
For both reason types we have the enum iwl_mvm_esr_state, when the
blocking reasons are stored in the `mvmvif::esr_disable_reason` bitmap.
This change introduces the APIs to use in the different cases:
- iwl_mvm_exit_esr - will exit from EMLSR mode.
- iwl_mvm_block_esr - will update the bitmap and exit EMLSR, to
be used for the blocking reasons only.

Calculation of a link grade is done as follows:
1. get the estimated throughput according to the RSSI of the link, this
will be the base grade
2. get the channel load from the BSS Load Element, subtracting the load
caused by us. Apply the factor on the grade.
3. puncturing factor: calculate the percentage of the punctured
subchannels (out of the total subchannels). Apply this on the grade.

In the previous commit, I renamed the variable to differentiate
mac80211/mvm link STA, but forgot to adjust the check. The one
from mac80211 is already non-NULL anyway, but the mvm one can
be NULL when the mac80211 isn't during link switch conditions.
Fix the check.

When scanning on 6 GHz we allocate a set of short-SSIDs and BSSIDs to
probe. However, when we need to do an active scan because of a hidden
SSID, then we could add too many entries for probing causing an
assertion in the firmware input validation.
Reshuffle the code a bit to first calculate the maximum number of
short-SSIDs and BSSIDs that are permitted for the channel. Then ensure
that we do not set more than the permitted number of bits in the
bitmasks and turn on force_passive when we have surpassed the limit.
While at it, also change the logic so that allow_passive is always
disabled in case a hidden SSID is included. Previously, we might not
have done so if we added the short-SSID based on the number of BSSIDs
already in the request.

The firmware has handled quiet in CSA for a long time now, but
it didn't really matter much. However, now with quiet CSA on a
perhaps secondary link, we don't want mac80211 to stop queues,
we can continue using a link that's not requiring quiet. Set
the feature flag for MLO-capable devices indicating that we'll
handle the quiet entirely in the driver/device.
However, the firmware doesn't handle quiet in AP mode since we
don't really expect to really be needing that (without radar
detection), but - even for testing - make that work properly
by simply not pulling from TXQs in this scenario.

If, for any reason, we're going to attempt to flush the queues
while quiet CSA is happening, this cannot succeed. This could
be the case if for example mac80211 were to flush after TXing
e.g. a deauth frame due to disconnecting during the CSA.
In this case, drop the frames instead, the firmware won't let
us do any transmissions and may also become unhappy if we're
not going to disconnect quickly enough.
Currently this doesn't happen as mac80211 stops queues, but
we'll want to let mac80211 know not to stop queues for proper
multi-link support during CSA, so we need to handle this case.

Do not call iwl_mvm_mld_get_primary_link if only one link
is active.
In that case, the sole active link should be used.
iwl_mvm_mld_get_primary_link returns -1 if only one link
is active causing a warning.

MLO ended up not really fully stable yet, we want to make
sure it works well with the ecosystem before enabling it.
Thus, remove the flag, but set WIPHY_FLAG_DISABLE_WEXT so
we don't get wireless extensions back until we enable MLO
for this hardware.

Pull thermal control updates from Rafael Wysocki:
"These mostly change the thermal core in a few ways allowing thermal
drivers to be simplified, in particular in their removal and failing
probe handling parts that are notoriously prone to errors, and
propagate the changes to several drivers.
Apart from that, support for a new platform is added (Intel Lunar
Lake-M), some bugs are fixed and some code is cleaned up, as usual.
Specifics:
- Store zone trips table and zone operations directly in struct
thermal_zone_device (Rafael Wysocki)
- Fix up flex array initialization during thermal zone device

A few models require *.pnvm files while we don't declare them via
MODULE_FIRMWARE(). This resulted in the breakage of WiFi on the
system that relies on the information from modinfo (e.g. openSUSE
installer image).
This patch adds those missing MODULE_FIRMWARE() entries for *.pnvm
files.

All of the thermal_zone_device_register_with_trips() callers pass zero
writable trip points masks to it, so drop the mask argument from that
function and update all of its callers accordingly.
This also removes the artificial trip points per zone limit of 32,
related to using writable trip points masks.
No intentional functional impact.

It is now possible to flag trip points with THERMAL_TRIP_FLAG_RW_TEMP
to allow their temperature to be set from user space via sysfs instead
of using a nonzero writable trips mask during thermal zone registration,
so make the iwlwifi code do that.
No intentional functional impact.
Note that this change is requisite for dropping the mask argument from
thermal_zone_device_register_with_trips() going forward.

In the operational statistics notifications (both old and new
API) the driver receives the statistics per phy.
currently this statistics wasn't handled because they wasn't needed.
Now the channel_load_by_us parameter in these statistics will be used
for the link grading calculation (implemented in another patch),
so store its value in phy_ctxt.
