The max transmit power of Standard Power (SP) Access Points (AP) on
6 GHz band and APs on 2.4 GHz and 5 GHz bands is limited by effective
isotropic radiated power (EIRP), while the max transmit power of Low
Power Indoor (LPI) APs on 6 GHz Band is limited by power spectral
density (PSD). Therefore the max transmit power of LPI APs grows as the
channel width increases, similar to the noise power which has constant
PSD.
Adjust the RSSI, SNR and throughput estimate based on max transmit power
config and max channel width in the roaming algorithm.

Overwriting of SSID for the hidden OWE BSS entry has some side effects:
- first the entry is notified over DBus with empty SSID and the update
of SSID is never signaled (it is not even possible at the moment to
notify the SSID change - see wpas_dbus_bss_signal_prop_changed()),
- during (and after) association there will be multiple entries
referring to the same BSSID/SSID pair.
Stop overwriting the SSID in an existing BSS entry based on OWE
transition mode information. Instead, depend on a new BSS entry getting
added for the hidden OWE BSS based on active scans for the SSID learned
from the open BSS. This would not have been sufficient for the initial
OWE design, but with the optimized scanning behavior from commit
c04562e67e ("OWE: Improve discovery of OWE transition mode AP"), this
can now depend on the exact same mechanism as other uses of hidden
SSIDs. This helps in keeping the D-Bus interface in sync with the BSS
parameters.

Drivers will often report regdom changes in the middle of a scan if they
detect during that scan that the regulatory domain has changed. If this
happens and we enter a regdom that supports 6 GHz channels when the
previous one didn't (this often happens in 6 GHz-capable regdoms for
devices after suspend/resume), immediately trigger a 6 GHz-only scan if
we were not able to connect to an AP on a legacy band.
This should significantly improve connection time to 6 GHz AP after
regdom has been reset.

wpa_supplicant was skipping MLD APs from network selection when the AP
advertise legacy open, WPA2-Personal-only (PSK without SAE), or PMF
disabled. However, there are already some early Wi-Fi 7 APs in the
market which advertise legacy open, WPA2-Personal-only, or PMF disabled
even though these combinations are unlikely to be allowed for Wi-Fi 7 in
the end.
To avoid connectivity issues with such APs, allow stations to connect
with MLO disabled when an AP MLD is detected to advertise legacy open,
WPA2-Personal-only (PSK without SAE), or PMF disabled.
This reverts commit 7d8b96dcfd ("wpa_supplicant: Apply same
restrictions for MLD as for 6 GHz BSS") except WEP and TKIP checks,
i.e., AP MLDs which advertise only WEP or TKIP are still skipped from
network selection.
For the SME-in-wpa_supplicant case, skip configuring MLD parameters to
the driver if the STA can connect only in legacy open,
WPA2-Personal-only, or PMF disabled mode. For the SME-in-driver case, it
is the driver's responsibility to initiate connection with MLO disabled
with such APs.

The driver-initiated BSS selection case and the "Network configuration
found for the current AP" case ended up clearing the RSN state machine
information on AP RSNE/RSNXE. That could result in incorrect behavior if
some key management operations depended on accurate information. For
example, this could result in not deriving the KDK as part of the PTK
derivation and failing to complete 4-way handshake if both the AP and
the STA indicated support for Secure LTF.
If the scan results for the selected BSS are available, use those to
update the RSN state machine AP RSNE/RSNXE similarly to the way this is
done with wpa_supplicant selects the BSS instead of clearing that
information in the RSN state machine.

If a higher priority BSS has invalid security parameters, e.g., an
invalid SAE password, and a lower priority BSS is discovered only after
the local network profile has been temporarily disabled, the BSSID
ignoring mechanism is not sufficient to allow the lower priority BSS to
be tried and all consecutive attempts will continue to use the higher
priority BSS. This might prevent connection in some unexpected cases
with invalid network configuration.
Extend BSSID ignoring mechanism to work in this type of a case by
ignoring the BSSID that resulted in disabling the SSID temporarily
during the first connection attempt after having re-enabled the SSID.
This allows a lower priority BSS, if any is available in scan results,
to be tried next to see if it might have working security parameters.
