3b67a20bb0 wifi: iwlwifi: mvm: offload BTM response during D3 
There are mainly two types of BTM (BSS Transition Management)
requests, recommendations and notifications. For the first type,
a response is needed otherwise, most probably the STA will be
disconnected.
Since we don't want to wake up the host on it, set the BTM to reject
offload flag (if the device supports it) and rely on the FW to take
care of it. The FW will reject the BTM request and in case the AP
sends DEAUTH the FW can wake up the host to let it decide on the
next steps.

b70813e4a8 wifi: iwlwifi: update response for mcc_update command 
Add support for the MCC update response version 8.
Versions 5-6 are already covered by the existing
flags conversion, and 7 isn't used.

The capabilities field in iwl_mcc_update_resp is 32 bits
wide now, and the flags moved, so some more changes are
needed.

While at it, convert the flags to bool (to avoid having
to deal with BIT(16) specially etc.) and use the
struct_size() macro for the memory allocation.

6b5a87df8e wifi: iwlwifi: mvm: align to the LINK cmd update in the FW 
The LINK cmd host api has been updated. Align the driver to the
new changes. Also, temporary use mac_id for link_id.
Using the phy_id as the link_id is wrong since we might have 2 macs
operating on the same phy - in this case we will have 2 different
links (one for each mac) with the same link_id. On the other hand,
since we don't have MLO implemented yet, we won't have 2 different
links of the same mac. Therefore, we can use the mac_id as the
link_id.

c7eca79def wifi: iwlwifi: mvm: report hardware timestamps in RX/TX status 
For TM/FTM frames, report the hardware timestamps reported by the
fw as part of the RX/TX status. Since the fw reports the timestamps
in a dedicated notification (and not as part of the RX/TX status),
hold the frame until the fw timestamps notification is received.
Timestamping is enabled when a station is connected and disabled
when disconnected. For AP interface, only the first station will
have timestamping enabled since the fw only supports timestamping
for one peer.

In order to support MLD, the key API is also changing to have
station masks instead of just the station ID etc. Change the
driver to support this, and add the new code in a new file so
it's more clearly separated.

For now this isn't separated at the mac80211 ops level, which
we wanted to do, but we're calling these functions in a place
when pre-start keys are installed in iwl_mvm_start_ap_ibss(),
and the function has some glue logic to mac80211. We may want
to change that later.

4da46a06d4 wifi: iwlwifi: mvm: Add support for wowlan info notification 
IMR (Isolated Memory Regions) is a mechanism to protect memory regions
from unwarranted access by agents in the system that should not have access
to that memory.

When IMR is enabled, pages in the DRAM will be located within the IMR
memory space, accessible only by the device.
As a side effect, during S4 (a.k.a hibernate) the IMR memory space
is not retained.

While the DRAM is saved to the disk and restored by the OS upon resume,
the IMR, which is hidden from the OS neither saved upon suspend nor
restored upon resume.

As a consequence of the above, it turned out that commands cannot
be sent as part of the resume flow, and so after ending
d3 the FW needs to use notifications instead of cmd-resp.

The resume flow becomes asynchronous, with a series
of notifications, starting with wowlan_info_notif, through
wowlan_pkt_notif and complete the resume flow by d3_end_notif.

This patch adds the support for wowlan info notification.

The wake packet has been removed from the wowlan info struct
and will be handled in a dedicated notification.

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

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.
