When fips_enabled is set, keys will not be given to the
hardware by mac80211 since the hardware isn't certified.
In this case, various features cannot work correctly as
the firmware needs to handle frames, but it then cannot
since no keys are available.
Disable features:
- WoWLAN since no keys etc.
- MFP since some frames need to be handled in firmware
- EHT/6GHz since MFP is required
Also restrict A-MSDU size since A-MSDUs cannot be split
up by hardware and thus need to fit into the RX buffers
in one piece.

When connected to an AP, the PHY will typically be tuned to
a higher bandwidth than the beacons are transmitted on, as
they are normally only transmitted on 20 MHz. This can mean
that another STA is simultaneously transmitting on another
channel of the higher bandwidth, and apparently this energy
may be taken into account by the PHY, resulting in elevated
energy readings.
To work around this, track the firmware's corrected beacon
energy data and replace the RSSI in beacons by that. The
replacement happens for all beacons received in the context
of the current MAC or link (depending on FW version), in
which case the filters will drop all else. For a scan, which
is only tuning to 20 MHz channels, the MAC/link ID will be
one that isn't found (the AUX ID 4), and no correction will
be done (nor is it needed.)

Since the iwlmvm driver now only supports pre-MLO devices,
we no longer need to maintain an extra explicit link ID;
valid MAC IDs and link IDs are both in the range 0-3 and
the driver always has a 1:1 MAC/link correspondence. Thus,
simply use the MAC ID as the link ID as well.
This simplifies some further work because on RX the ID is
given but there is some confusion about which versions of
the firmware report MAC and which report link ID.
While at it, clarify iwl_mvm_handle_missed_beacons_notif()
code a bit so it doesn't look like an invalid vif pointer
is being used.

In the current code, if there was a rekey, we remove all the existing keys
from mac80211, then re-add the ones that the FW sent with
ieee80211_gtk_rekey_add, (newer FW will send also the existing GTKs/BIGTKs)
and then update the sequence number.
Instead of removing and re-adding the existing keys for no good reason,
we can just update the sequence of all keys, also of the ones that are
going to be replaced, and update again after the replace.
This change is required because ieee80211_gtk_rekey_add is going to be
changed to lookup the cipher from the old key instead of receiving it as an
argument, and for this it will need the old key(s), so we can't remove all
keys.
Note that with this change, in case that a key that existed before wowlan
is replaced, mac80211 will now call the driver to remove the old key and
add the new one (as opposed the previous behaviour, in which the key was
removed by the driver itself).
Of course we don't want to run the set_key callbacks in this case, so just
return early.

Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.
To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM
By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

There are a number of MAC parameters that are in the iwl_cfg

This isn't necessary, there are many more of those than MACs,
so move (most of) the data into the MAC family config struct.
Note that DCCM information remains for use by older devices,

There are two cases in which the min_def isn't used:
a) if FILS will be enabled
b) if FTM responder is enabled
Both of these apply to AP mode only, but for FILS we're
not checking that right now. Change the code to iterate
the interfaces and links using the channel context, and
check for AP mode for both, not just for FTM responder.
In the case of iwl_mvm_enable_fils() this might also fix
an issue where FILS is enabled for an IBSS network that
happens to be started on 6 GHz, though that's not very
likely to be possible due to regulatory.
However for RX OMI bandwidth reduction the driver needs
to use the min_def in client mode as well, in order to
actually reduce bandwidth when it requested that.

My recent restart related work has made this race more likely
to happen and we've now noticed it, but it seems that it was
always possible. The race is that the add stream work can be
scheduled just before a restart is scheduled and then execute
before the restart, accessing the device while it's doing the
restart and not accessible.
To fix this, check if the device is restarting and abort the
work in that case. Reschedule it after the restart as well.

In order to later add the ability to do deeper resets of the
device when it crashes, first restructure the firmware error
handling. Instead of having just a single nic_error() method
that handles all, split it:
- nic_error() just handles and prints the error itself,
- dump_error() synchronously creates an error dump, and
- sw_reset() will be called to request doing a SW reset.
This changes the architecture so that the transport is now
responsible for deciding how to do the reset, and therefore
the handling of reprobe if error occurs during reconfig
moves there, which necessitates adding a method there that
notifies the transport that the recovery was completed.
Actually introducing the model under which deeper resets can
be done will be in future patches.

Approximately three years ago, in commit ddb6b76b6f
("iwlwifi: yoyo: support TLV-based firmware reset"), the code
was (likely erroneously) changed to no longer treat error
interrupts as firmware errors. As a result, this meant that
the fw_restart counter was only applied in case of command
queue being stuck, which never seems to happen. Also, there's
no longer any way to set the mvm->fw_restart to a value that
doesn't match exactly the module parameter behaviour.
Instead of trying to fix this, simply remove the logic that
limits the number of restarts, it's clearly unused.
However, restore the logic that restart isn't unconditional,
by checking the module parameter.
Since the "fw_error" argument to iwl_mvm_nic_restart() is now
always true (except in the "never happens" case of CMD queue
stuck), just remove it too and treat command queue stuck the
same way as everything else.

Currently, the sequence goes like this (among others):
1. flush all stations (including the AP ones) -> this will tell the
drivers to remove the stations
2. notify the driver the vif is not associated.
Which means that in between 1 and 2, the state is that the vif is
associated, but there is no AP station, which makes no sense, and may be
problematic for some drivers (for example iwlwifi)
Change the sequence to:
1. flush the TDLS stations
2. move the AP station to IEEE80211_STA_NONE
3. notify the driver about the vif being unassociated
4. flush the AP station
In order to not break other drivers, add a vif flag to indicate whether
the driver wants to new sequence or not. If the flag is not set, then
things will be done in the old sequence.

Since we no longer shut down the device in suspend, we also no longer
call iwl_mvm_mei_device_state() and this is a problem because iwlmei
expects this to be called when it runs its own suspend sequence. It
checks mei->device_down in iwl_mei_remove() which is called upon
suspend.
Fix this by telling iwlmei when we're done accessing the device.
When we'll wake up, the device should be untouched if CSME didn't use it
during the suspend time. If CSME used it, we'll notice it through the
CSR_FUNC_SCRATCH register.

This feature can be used on ax200 as well. It'll avoid to restart the
firmware upon suspend / resume flow. Doing so also avoids releasing and
re-allocating all the device related memory which makes the memory's
subsystem task easier.

This is written only with wiphy and mvm mutexes held, but in
order to actually rely on that document it and add lockdep

Revert commit dfdfe4be18 ("wifi: iwlwifi: remove retry loops in
start"), it turns out that there's an issue with the PNVM load
notification from firmware not getting processed, that this patch
has been somewhat successfully papering over. Since this is being
reported, revert the loop removal for now.
We will later at least clean this up to only attempt to retry if
there was a timeout, but currently we don't even bubble up the
failure reason to the correct layer, only returning NULL.

Release the link mapping resource in AP removal. This impacted devices
that do not support the MLD API (9260 and down).
On those devices, we couldn't start the AP again after the AP has been
already started and stopped.

It can happen that more errors occur after a firmware assertion. In that
case, having another log message after the restart has completed makes
it easier to see which errors where still part of the restart flow.

Implement the prep_add_interface() callback, so that in case
EMLSR is active and an AP or a P2P interface is do to be added,
EMLSR would be blocked.
Add a delayed work, so that in case that the interface was not
eventually added, EMLSR would be unblocked after 5 seconds.

In order to update the right link information, call the update
rate_control_rate_update() with the right link_sta, and then
pass that through to the driver's sta_rc_update() method. The
software rate control still doesn't support it, but that'll be
skipped by not having a rate control ref.
Since it now operates on a link sta, rename the driver method.
