b5d6175c11 wifi: iwlwifi: mld: Replace static declarations of IWL_MLD_ALLOC_FN 
Replace static declarations of IWL_MLD_ALLOC_FN with a new macro
IWL_MLD_ALLOC_FN_STATIC that declares the static.

This is needed to resolve issues with spatch, which fails to handle
functions after "static IWL_MLD_ALLOC_FN".

90cec2c954 wifi: iwlwifi: define MODULE_FIRMWARE with the correct API 
A firmware API of a mix and match (MAC + RF) is the lower one of the
two. But the MODULE_FIRMWARE of QU/QUZ/SO/MA/TY with GF/HR, was defined
using the max API of GF/HR, which is 100, instead of the max API of
QU/QUZ/SO/MA/TY, which are API 77/89.
Therefore, the wrong firmware files were published in the modinfo,
leading to missing firmware files.

Fix this by using the right API when declaring MODULE_FIRMWARE.

While at it, add a IWL_FW_AND_PNVM entry for SO and GF4, that was
missing.

59a26553f1 wifi: iwlwifi: mld: Add support for multiple NAN Management stations 
The following limitations arise from the current FW support for NAN:

- While NAN synchronization and discovery beacons are sent
  internally by the firmware, the BIGTK is configured to the
  auxiliary station associated with the NAN operation. Thus,
  the beacons are transmitted unprotected.
- The auxiliary station cannot be configured with support for
  management frame protection as this is not supported by the
  firmware. Thus, there is no way to protect the SDFs and the
  NAFs.

To overcome the above limitations the firmware introduced the
following new station types:

- NAN broadcast station: Used for NAN synchronization and
  discovery. i.e., used for beacon transmissions. A BIGTK
  can be configured to this station and thus beacons can
  be transmitted with protection.
- NAN management station: Used for sending SDFs and NAFs.
  This station can be configured with support for management
  frame protection etc.

Modify the iwlmld logic to support the older and the newer
firmware designs. As no Tx queue is needed for the NAN
broadcast station, modify the internal station support
to allow adding/removing a station without a queue. In
addition, since no links are associated with these stations,
modify the internal station support to allow adding a station
without a link mask.

The oldest core that devices that load iwlmld op mode are supporting is core 101.
Core 101 has version 7 of iwl_compressed_ba_notif, so earlier versions
are no longer needed.

FW has a limitation of how many multicast management keys it supports.
Until today we just assumed this limitation. But now as it is changing,
due to NAN, we need a clear indication from the FW so we know how many

Read and store this indication from the FW's TLV.

646381b378 wifi: iwlwifi: mld: track TX/RX IGTKs separately 
Due to FW/HW limitations and the MME being at the end of the
frame, the devices only support a single IGTK for RX. For TX
multiple aren't needed, only the latest will be used, but in
the device there are space restrictions, so we can also only
install one.

For NAN, however, we will have one for RX for each peer, and
one for ourselves to transmit with.

Separate out the tracking of IGTK: instead of being per link
make the TX ones per link and the RX ones per (link) station.

Note that we currently hardcode that the FW can only have two
(IWL_MAX_NUM_IGTKS) IGTKs, which won't be sufficient for NAN
with security, concurrently with BSS.
