iwlwifi: support version 5 of the alive notification
Add support for the new version of the alive notification, which
includes the SKU ID. We don't use the SKU ID yet, so we can just
handle the new notification as if it were version 4.
While at it, clean up a bit and rename the command and structure names
in the comments so that they are aligned with the ones used in the FW.
The scan request may specify the request scan dwell time.
However, this value may not always be optimal (e.g. short dwell
time for a passive channel). This may happen in a scan request
as a result of beacon report request, in which the AP may request
an active scan, thus setting a short dwell time, but the station
will perform a passive scan due to regulatory.
Ignore the scan duration parameter and always use the internal
scan dwell time which should be optimal.

iwlwifi: mvm: initiator: add option for adding a PASN responder
Add an option for adding a PASN responder, specifying the HLTK and
TK (if not associated). When a receiving a range request for a
PASN responder, the driver will ask for a secured measurement with
the specified HLTK and TK.
iwlwifi: mvm: responder: allow to set only the HLTK for an associated station
For secure ranging with an associated station, the driver only needs
to set the HLTK. There is no need to add an internal station for PMF
since the FW will use the existing station which already has the TK
installed.
The overcome instabilities in the RTT results add smoothing logic
to the reported results. In short, the smoothing logic tracks the
RTT average of each responder for a period of time, and in case
a new RTT results is found to be a spur, the tracked RTT average
is reported instead of the current RTT measurement.
Smooth logic debug configuration using iwl-dbg-cfg.ini:
- MVM_FTM_INITIATOR_ENABLE_SMOOTH: Set to 1 to enable smoothing logic
(default=0).
- MVM_FTM_INITIATOR_SMOOTH_ALPHA: A value between 0 - 100, defining
the weight of the current RTT results vs. the RTT average tracked
based on the previous results. A value of 100 means use only the
current RTT results.
- MVM_FTM_INITIATOR_SMOOTH_AGE_SEC: The maximal time in seconds in which
the RTT average tracked based on previous results is considered valid.
- MVM_FTM_INITIATOR_SMOOTH_UNDERSHOOT: if the current RTT is positive
and below the RTT average by at least this value, report the average
RTT instead of the current one. In units of picoseconds.

However, if there was any Tx still in-flight (tx-cmd was sent but the
ba-notif wasn't received yet) the ba-response to those frames is simply
ignored without actually reclaiming anything. This later causes the
driver to think that that some of the station's queues aren't empty when
in practice they are which causes errors in the station remove flow.
Fix this by performing the tx-reclaim also if the rcu is invalid. any DB
that can't be updated due to this is not very important at this stage
since the station is about to be removed soon anyways.

In the transmit power table, it is important to know what the regulatory
currently is. For different regulatories, there are different
transmit power limits. Show which regulatory the driver is currently
using.
This patch adds a function which is able to dump firmware fifo when
firmware crashes. If firmware needs more than one time to dump all logs,
it will set a bit called "more bit" in the header of the first log, and
driver needs to set a register to inform firmware that it is ready for the
next dump.
Rtw88 currently has a function to dump reserved page section of the
firmware fifo. Reserved page is just part of the firmware fifo, there
are multiple sections in the firmware fifo for different usages, such as
firmware rx fifo and tx fifo.
This commit adds a function to check not only the reserved page section
but also other parts of the firmware fifo. In addition, we need to dump
firmware fifo to dump the debug log message if firmware crashes.
This handles the situation when firmware crashes.
When firmware crashes, it will send an interrupt, and driver will queue
a work for recovery.
In the work, driver will reset it's internal association state, which
includes removing associated sta's macid, resetting vifs' states
and removing keys. After resetting the driver's state, driver will call
rtw_enter_ips() to force the chipset power off to reset the chip.
Finally, driver calls ieee80211_restart_hw() to inform mac80211 stack
to restart.
Since only 8822c firmware supports this feature, the interrupt will only
be triggered when 8822c chipset is loaded.
The vht capability of MAX_MPDU_LENGTH is 11454 in rtw88; however, the rx
buffer size for each packet is 8192. When receiving packets that are
larger than rx buffer size, it will leads to rx buffer ring overflow.
