This version adds the following configuration options:
1. Set the BSS color for NDP ranging
2. Set the minimum and maximum time between measurements for
non trigger based NDP ranging.
3. Terminate the session in case the responder requests LMR feedback.

When doing scan while 6GHz channels are not enabled, the 6GHz band
is not scanned. Thus, if there are no APs on the 2GHz and 5GHz bands
(that will allow discovery of geographic location etc. that would
allow enabling the 6GHz channels) but there are non collocated APs
on 6GHz PSC channels these would never be discovered.
To overcome this, FW added support for performing passive UHB scan
in case no APs were discovered during scan on the 2GHz and 5GHz
channels.
Add support for enabling such scan when the following conditions are
met:
- 6GHz channels are supported but not enabled by regulatory.
- Station interface is not associated or less than a defined time
interval passed from the last resume or HW reset flows.
- At least 4 channels are included in the scan request
- The scan request includes the widlcard SSID.
- At least 50 minutes passed from the last 6GHz passive scan.

Add support to the 6GHz band (aka. Ultra High Band or UHB). This
allows us to scan and connect to channels in that band, including all
the relevant features, such as preferred scan channels, colocated
channels etc.

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.
- MVM_FTM_INITIATOR_SMOOTH_OVERSHOOT: if the current RTT is positive
and above the RTT average by at least this value, report the average
RTT instead of the current one. In units of picoseconds.

The purpose of this was to keep all the queues updated with
the Rx sequence numbers because unlikely yet possible
situations where queues can't understand if a specific
packet needs to be dropped or not.
Unfortunately, it was reported that this caused issues in
our DMA engine. We don't fully understand how this is related,
but this is being currently debugged. For now, just don't send
this notification to the Rx queues. This de-facto reverts my
commit 3c514bf831ac12356b695ff054bef641b9e99593:
iwlwifi: mvm: add a loose synchronization of the NSSN across Rx queues
This issue was reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=204873https://bugzilla.kernel.org/show_bug.cgi?id=205001

Certain APs (I think a certain Broadcom model) interact badly with our
full state BA bitmap handling, and if triggered badly with many powersave
transitions they keep sending frames from before the window, which our
hardware then doesn't appear to ACK (to them) since it has moved on and
is sending ACKs for higher SNs now.
Try to detect this situation and if this keeps happening, disable the
aggregation session.

Try to detect that the AP is not using aggregation even when there's
enough traffic to make it worthwhile; if this is the case and U-APSD
is enabled then assume the AP is broken (like so many) and doesn't
enable aggregation when U-APSD is used. In this case, disconnect from
the AP and blacklist U-APSD for a potential new connection to it.
