46345ed362 wifi: iwlwifi: Fix botched indexing conversion 
The conversion from compiler assisted indexing to manual
indexing wasn't done correctly. The array is still made
up of __le16 elements so multiplying the outer index by
the element size is not what we want. Fix it up.

This causes the kernel to oops when trying to transfer any
significant amount of data over wifi:

f2829c89e2 wifi: iwlwifi: mvm/mld: use average RSSI for beacons 
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.)

91b9f31d5c wifi: iwlwifi: mvm: remove extra link ID 
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.

ea045a0de3 wifi: iwlwifi: add support for accepting raw DSM tables by firmware 
Firmware would assert on undefined bits in DSM-originated DWs.
With this change, Firmware introduces a fail-safe mechanism
and removes the assert behavior. This ensures robustness when
handling raw DSM table data.

8580be27e2 wifi: iwlwifi: mld: don't remove all keys in mcast rekey 
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.

5bc741e1b1 wifi: iwlwifi: fix HE/EHT capabilities 
The default capabilities were set to much more than the hardware
currently is intended to support, and then masked off for only
the GL MAC type. However, this was due to some miscommunication
and is incorrect, it should've been masked off for all current
and planned MACs/RFs. Instead of doing this removing and adding
of capabilities, simply list the ones that currently apply to
all devices. If this changes for a new device type we can change
the code, but at least the driver won't erroneously advertise
some capabilities that aren't actually implemented in hardware.

afcefc58fd wifi: ath12k: Fix packets received in WBM error ring with REO LUT enabled 
Currently, packets are being received into the WBM error ring when
REO queue lookup is enabled, resulting in degraded RX performance.
The issue arises because the REO queue LUT TID memory reference is
set to zero-it's being assigned before the memory is allocated.
Fix this by assigning the REO queue TID memory reference in the LUT
immediately after memory allocation to ensure correct packet
processing.
