Userspace/framework tracks last few days(e.g: 10 days) history of
connected APs and maintains best 10 channels out of that list by
considering multiple parameters like scoring, location etc.
It's likely to find an AP in one of these channels when a scan issued.
So, framework issues first scan request with a maximum of 10 channels
in the below cases currently,
1. When the wifi is turned on
2. When the wifi is in disconnected state and user turns on the screen.
Host driver shouldn't add any more channels to this scan request as
it's expected to complete the scan as soon as possible to connect
quickly to the known APs. Don't add 6g RNR channels also in the
scan request.
Further scans from framework would be full scans or with list a
of channels(more than 10) and RNR channels can be added to them.
Also, don't add all 6g channels if userspace hasn't given any as
the current framework/kernels are matured enough decide whether to
issue scan with 6g channels or not. RNR channels can be added as
mentioned. Remove SCAN_MODE_6G_NO_OPERATION as it's not needed
anymore with this.
Also, 6ghz scan functionality gets enahanced depending on various
requirements. This can be moved to a separate file so that core
scan_manager.c file won't be bloated with new code.

Currently, vendor scan request is enqueued in the scan queue first and
then posted into the scheduler queue. Now if there is an SSR in between,
then scan request will be freed twice. Once in SSR context and again
in the caller context because scan scheduling fails due to user disabled
the scan.
To resolve this, post the scan request in scheduler queue first. Once
scan request scheduling is success, then enqueue the scan request in
scan queue. This approach can lead to a race condition like after
scheduling scan request, host may get scan response from firmware even
before the scan request is queued. To avoid this race, scan request
scheduling and enqueue should be protected by scan_req_q_lock.

The roam sequence in LFR-3.0 is roam scan start notification
from firmware followed by roam start indication and then
roam synch,roam synch frame events. Roam start is sent
after candidate selection and host driver will disable
queues when roam start is received.
But for emergency roam trigger, firmware sends roam start
indication directly without notifying roam scan start to disable
data path queues immediately after deauth received from the AP.
So roam start is received before roam scan is started at firmware
and before candidate selection is done.
After roam start notification, host sends scan abort for all scan
on vdev by setting scan command request type to
WMI_SCN_STOP_VAP_ALL. This results in roam scan getting aborted at
firmare in emergency deauth roaming case and roaming fails.
Introduce new vdev id value based on which the scan module will
abort only host triggered scans setting the flag
WMI_SCN_STOP_HOST_VAP_ALL in the scan request.

Depending on the requirement, a bigger size or a smaller size for
the frequency variable can be chosen. The advantages of each size
are described below:-
Advantage of a bigger size:
When two technologies (e.g. 802.11AX and 802.11AD ) are controlled
by the same driver software, the frequency range may be very large
and a bigger size (e.g. 32bit integer) is more appropriate.
Advantage of a smaller size: When the frequency range is not very
large, a smaller size(e.g. 16bit integer) can be used. It saves a
large amount of space especially when many large arrays containing
elements of this type/size are defined in the driver.
Also, change the size of the IEEE channel variables to unsigned
8-bit integer.
