While parsing MBSS IE split profiles, bssid copy flag
is not reset in between sub element parsing resulting
in skipping the bssid copy for next non tx profile.

scanning all supported channels.

The earlier logic for scanning non-inheritance IE fails if
non transmitted bssid profile has any extension element
such as MU EDCA before the extension element with
non-inheritance IE.
Since MU EDCA is also an extension element and it does not
have noninheritance element id in it, the logic used to fail
as the driver does not check further for any other extension
element ID in non transmitted bssid profile. Because of this
the IEs part of non-inheritance list used to get inherited,
causing disconnection issue.
With current fix, the scanning for non-inheritance IE has been
taken care properly. Driver will go through the non transmitted
bssid profile until it finds the extension element with
non-inheritance element ID in it.

Currently, scan requests are optimized to trim 6g channels based
on the ini params scan_mode_6ghz and scan_mode_6ghz_duty_cycle.
But RRM scan request comes to host driver with a fixed set of
channels and the expectation is to scan all supported channels
out of these.
Don't consider scan_mode_6ghz_duty_cycle to optimize the
channels in case of RRM scan request. Thereby no 6g channels
would be trimmed.
Ini param "scan_mode_6ghz" is still honored if it's set to
"SCAN_MODE_6G_NO_CHANNEL", which filters out all 6g
channels from the scan request.

If there is any non-inheritance element present as part of the
nontransmitted BSSID profile then while generating scan entry
for that profile, driver need not inherit those list of
element IDs and list of element ID extensions from the
transmitted BSSID profile.
Since non-inheritance element is an element ID extension, it
should be part of extension element. So the logic we use over
here is to find if there are any extension element present in
the nontransmitted BSSID profile. if yes, then only go ahead
with below logic or else go with the normal flow.
Logic:
Mark and store the start of the list of element IDs and
list of Element ID extension.
While generating the new ie for the non transmitted BSSID
profile, do not inherit the IEs present in the above
mentioned lists.

If any nontransmitted BSSID profile is fragmented across
multiple MBSSID elements, then it is called split profile.
For a split profile to exist we need to have at least two
MBSSID elements as part of the RX beacon or probe response
Hence, first we need to identify the next MBSSID element
and check for the 5th bit from the starting of the next
MBSSID IE and if it does not have Nontransmitted BSSID
capability element, then it's a split profile case.
This change is responsible in accumulating the non
transmitted BSSID profile, fragmented across multiple
MBSSIDs, so that the scan entry will not miss any
information.

To check if a scan entry is a non-Tx VAP of our connected BSS, the current
implementation of scm_age_out_entries() searches through all scan entries
to find out our connected BSS. This check takes O(n) time where n = number
of scan entries. Running this check in the main loop of
scm_age_out_entries() results in an overall time complexity of O(square(n))
Time complexity can be improved if we do one iteration over scan entries
to find out our connected BSS, and save it in a local variable, and then
use that local variable in the main loop of scm_age_out_entries().
With this approach, we just do two iterations over scan entries
instead of nested iterations.
