In my previous fix for this condition, I erroneously listed 9000
instead of 7000 family, when 7000/8000 were already using iwlmvm.
Thus the condition ended up wrong, causing the issue I had fixed
for older devices to suddenly appear on 7000/8000 family devices.
Correct the condition accordingly.

The 130/1030 devices are really derivatives of 6030,
with some small differences not pertaining to the MAC,
so they must use the 6030 MAC config.

This version doesn't provide the sta id, so we need to look it up -
assuming that no other sta exists, since one of the conditions of
entering OMI is not having P2P/TDLS.
But when we leave OMI, because of the P2P/TDLS activation, the P2P/TDLS
sta can already exist while we receive the notification from the FW.
This causes an error log which is incorrect.
Since OMI is only supported in SC, which is not shipped yet, no one will
use a FW with the old version.
Remove support for it.

If no frames are received on a queue for a while, the reorder buffer
head_sn may be an old one. When the next frame that is received on
that queue and buffered is a subframe of an AMSDU but not the last
subframe, it will not update the buffer's head_sn. When the frame
release notification arrives, it will not release the buffered frame
because it will look like the notification's NSSN is lower than the
buffer's head_sn (because of a wraparound).
Fix it by updating the head_sn when the first frame is buffered.

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.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
We have a flexible struct iwl_tx_cmd_v6 in the middle of a few structs,
but those don't even need the flexible part.
So, we add iwl_tx_cmd_v6_params, that will contain everything except the
flexible array and use this one for the containing structs.
Also, as part of the refactoring remove unused flex array `payload`.
So, with these changes, fix the following warnings:

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.
