When the beacon frame is received by the DUT, util_scan_get_phymode_5g
gets invoked. In a highly noisy environment, malformed/incorrect
beacon frames is received and the content of vhtop->vht_op_chwidth
becomes invalid. Hence bad channel print floods the console since
it is under scm_err debug level (the default debug level of SCAN module
is ERROR).
Reduce the debug level of the print to scm_debug since it hits for
every in-correct beacon.

While processing an beacon with MBSSID IE/ IEs, the driver
creates scan entries for the TX VAP/ profile and every Non-TX
profile present in the MBSSID IE.
The scan entry generation for nontx profile happens as required,
whereas while generating the scan entry for the TX VAP, driver
copies the MBSSID IE/IEs as well. Because of this, multiple
ML IEs would be part of one frame and as a result sometimes
supplicant fails in adapting/ fetching the proper ML IE.
With this change, the host driver takes care of stripping out
the MBSSID IE/IEs from the full beacon frame and while
generating the scan entry for TX VAP/ profile, it uses the data
that only belongs to the TX VAP.
This helps in resolving the duplicate ML IE issue.

Duplicated 6 GHz beacons with poor RSSI are received in frequency far away
from primary channel, they are not dropped because HE duplicate beacon
field is set, which makes poor RSSI saved in scan entry.
To fix it, if 6 GHz HE duplicate beacon field is set, compare band width
and center frequency from EHT ops and HE ops with current frequency beacon
received, if current frequency is outside of the BSS operating BW, drop the
leaked beacon.

1. MLO requires a tbtt_info length of 16 octets. To support
16 MLDs, it requires to extend the current global_rnr cache
accommodating this new requirement in 11be MLO context.
Redefine MAX_RNR_SIZE accordingly.
2. Currently, scan-module is considering only upto 5 reported
APs in a RNR element. This will be ok pre-11be as the RNR info
is not used for connection. RNR info is required for link to
vdev matching for MLO based connection starting 11be. So, the
limit specified by MAX_RNR_BSS needs to be extended to be able
to parse upto 16 tbtt_infos from the RNR elements present in
beacon or probe-response. Some APs can advertise upto 16 co-
MLDs when 6Ghz link is involved in those MLDs.

Due to the nature of discrete channel lists for each
power mode on the host driver, it is currently not
possible to scan 6GHz channels which are not part
of the operating regulatory power mode.
To enable scanning all 6GHz channels irrespective of the
regulatory power mode (i.e., standard, low, etc.), the
existing sanity checks for the regulatory current channel
list need to refer to the super channel list
instead.
Additionally, these sanity checks need to check the
channel state and flags for the best power mode instead
of the current power mode. This will allow the scan
manager to access all 6GHz channels irrespective
of the current regulatory power mode.
Multi-band operation (for radios operable on 2.4GHz,
5GHz and/or 6GHz) is also ensured in these sanity
checks.
