Some APs do not advertise operating classes correctly for BSS Transition
Management. Try to determine the most likely operating frequency based
on the channel number (1..14 --> 2.4 GHz; 36..177 --> 5 GHz) if invalid
op_class == 255 is received in a BSS Transition Management Request. This
speeds up the following operating by avoiding a full scan due to an
unknown channel.
This extends the workaround that was added in commit 80ce804e88 ("WNM:
Workaround for broken AP operating class behavior") for invalid
operating class 0 to cover another observed case with invalid operating
class 255.

If a scan triggers a regdom update into a 6 GHz-allowed regdom, and an
RNR element in one of the legacy band scan results points to a 6 GHz
scan result with a short SSID matching the current_ssid, delay
connection in favor of a 6 GHz-only scan. This will optimize the case in
which we first connect to a 5 GHz AP, then later roam to a 6 GHz one by
directly connecting to the 6 GHz one.

When non_coloc_6ghz = false, the STA is expected to scan for colocated
APs. However, if the colocated AP is on a non-PSC channel, it will not
be detected during the 6 GHz-only scan because the frequency list is
limited to PSC channels. Even when the NL80211_SCAN_FLAG_COLOCATED_6GHZ
is set, the cfg80211 only scans a subset of the channels in the original
6 GHz scan request. Therefore, this patch adds non-PSC channels to the
original 6 GHz scan request.

The preferred candidate list included bit just makes parsing the list

There was an ancient code path to trigger a scan that was apparently
forgotten when the code was extended over time. It does not make any
sense to trigger a scan twice, so remove the earlier scan.
The earlier scan call was avoiding to trigger a new scan if a fixed
BSSID is configured. This seems like a reasonable restriction to do, so
add this check before starting a scan.
Consolidate everything so that scanning happens at the end of the
functions unless we bail out before. Add a "reset" label for all other
cases to ensure that we don't leave things in the a bad state.

According to Multiband Operation specification (r17, section 3.5.2),
a BSS Transition Management Request with the disassociation imminent

This is enforced in case the request did not include a candidate list.
However, in case a candidate list was included but none of the APs in
the candidate list was found in the scan results, the request is
rejected.

Having it in wnm_is_bss_excluded() is more generic as it works for other
locations (e.g., MLD link selection). So move the test and add a check
for the abridged bit while at it. Note that without the abridged bit
check another check would be needed (e.g., checking wnm_dialog_token) to
ensure that there isn't a rejection unless a BTM is in progress.
compare_scan_neighbor_results() calls wpa_scan_res_match() which calls
wnm_is_bss_excluded() so the previous behavior is maintained for WNM

Commit e508c070c4 ("WNM: Keep BTM information until connection
completes") changed the logic so that much of the information about a
transition management request will be kept around for longer. However,
doing this also implies that the scan logic can be called multiple times
with wnm_dialog_token being set.
Add a guard to bail out if the scan was not done for a BTM request. But,
add it after the transition candidate validity check so that we reset
the state when a new scan invalidated it.
However, invalidation does not make sense for any scan, primarily an ML
probe request during a connection attempt should not trigger
invalidation. So move the call to wnm_scan_process() further down in the
list to avoid issues.

wpa_supplicant select_network() relies on fast_associate to reuse old
scan results. However, this approach does not apply in some cases in
Android:
1 - If the selected network is hidden, and the SSID is in Chinese,
Android switches between fallback SSIDs, necessitating a new scan for
switching between different hidden SSIDs.
2 - Similarly, if the selected SSID is OWE (Opportunistic Wireless
Encryption), and the OWE SSID bands have been changed, select_network()
requires a fresh scan to discover hidden OWE SSIDs.
To address these, enhance select_network() to trigger new scans instead
of relying on fast_associate. This improves network selection behavior
in Android.

When the wiphy supports multiple bands and reports different capability

ibss_mesh_setup_freq(). This issue arises because the modes of 5 GHz and

To address this, use function get_mode() to determine the appropriate

sets and ensures compatibility with the band of the channel supported in
