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.

Adaptive 11r is a feature by which the network supports 11r
even though the bss doesn't advertise 11r. This is done with the
help of advertising vendor specific adaptive 11r IE and MD IE
in the beacon/probe. When vendor specific adaptive 11r
IE (oui 0x00 40 96 type 0x2C) is present in the beacon/probe,
and 1st bit of the IE data is set to 1, then the BSS supports
adaptive 11r.
The BSS advertises, non-11r akm in RSN IE and user space will
send the 11r akm in the connect start. So the scan module
shouldn't filter out the candidate adaptive 11r supported BSS
with AKM mismatch reason.
Add changes in scan module to parse the Vendor specific adaptive
11r IE and copy it to the scan_entry ie_list. Check if
negotiated akm is non-11r akm, and the filter akm sent from csr
is a 11r akm (which is received from user space), then mark the
bss as matching.
