af3cdfd30c wifi: iwlwifi: use unsigned to silence a GCC 12 warning 
GCC 12 says:

drivers/net/wireless/intel/iwlwifi/mvm/sta.c:1076:37: warning: array subscript -1 is below array bounds of ‘struct iwl_mvm_tid_data[9]’ [-Warray-bounds]
 1076 |                 if (mvmsta->tid_data[tid].state != IWL_AGG_OFF)
      |                     ~~~~~~~~~~~~~~~~^~~~~

Whatever, tid is a bit from for_each_set_bit(), it's clearly unsigned.

We used to count the number of ieee80211_vifs in mvm.
This was needed for the legacy PM API, which is no longer

147eb05f24 iwlwifi: mvm: always tell the firmware to accept MCAST frames in BSS 
Make the firmware's life easier and always accept MCAST frames. If
needed, drop them in the driver. We need to filter out MCAST frames
in order not to have false positives in the decryption check. If we
accept MCAST frames before we have the GKT installed, we'll end up
complaining that we can't decrypt the frame.
Implement the same filtering, but in the driver.

046d2e7c50 mac80211: prepare sta handling for MLO support 
Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.

With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.

To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.

For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.

For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.

Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.

Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

b20bdd9cc9 iwlwifi: mvm: Don't fail if PPAG isn't supported 
When we're copying the PPAG table into the cmd structure we're failing
if the table doesn't exist in ACPI or is invalid, or if the FW doesn't
support PPAG setting etc.

This is wrong because those are valid scenarios.  Fix this by not
failing in those cases.

Some APs misbehave when TWT is used and cause our firmware to crash.
We don't know a reasonable way to detect and work around this problem
in the FW yet.  To prevent these crashes, disable TWT in the driver by
stopping to advertise TWT support.

During disassociation we're decreasing the phy's ref count.
If the ref count becomes 0, we're configuring the phy ctxt

the default channel is enabled or not. Fix it by configuring
the phy ctxt to the lowest channel which is enabled.

26de4c8b02 iwlwifi: mvm: update BAID allocation command again 
Due to some issues found in integration, the command now has
the (old) station mask and TID in modify/remove instead of
the BAID, adjust accordingly.

Since we don't use modify yet (and never will with v1 of the

that, this way we don't have to duplicate everything, only
the remove code.

227f25972c iwlwifi: support new queue allocation command 
Newer firmware versions will support a new queue allocation
command, in order to deal with MLD where multiple stations
are used for a single queue. Add support for the new command.

This requires some refactoring of the queue allocation API,
which now gets
 - the station mask instead of the station ID
 - the flags without the "enable" flag, since that's no longer
   used in the new API

Additionally, this new API now requires that we remove queues
before removing a station, the firmware will no longer do that
internally. Also add support for that.

c91b90b2e5 iwlwifi: mvm: Consider P2P GO operation during scan 
A scan during active P2P GO operation, i.e., data traffic with
clients, can impact the throughput and latency of such traffic.
Thus, when scan is requested while there is an active P2P GO
and low latency is asserted:

- Ask the FW scan logic to respect the P2P GO activity during the
  scheduling of the scan operation to minimize the impact on the
  throughput and latency.
- Force scan to perform EBS before starting the scan to reduce the
  number of scanned channels.

Non PSC channels should generally be scanned based on information about

should not be scanned unless specifically requested so (as there are
relatively many non PSC channels, scanning them passively is time consuming

Thus, modify the scan logic to avoid passively scanning PSC channels
if there is no information about collocated APs and the scan is not
