As a workup action during disassociation, wpa_supplicant checks if the
disconnection could have been caused by PSK mismatch during WPA 4-way
handshake with function could_be_psk_mismatch() in event.c. A MSG_INFO
message will be sent on the control interface when there could be a PSK
mismatch, and this heuristic can be useful to indicate if the
disconnection is caused by a wrong passphrase provided by the user.
Here, propagate a new D-Bus signal 'PskMismatch' to notify other
applicantions.

Enable MLO for SAE authentication when the driver indicates the AP MLD
address in an external authentication request. The MAC address of the
interface on which the external authentication request received will be
used as the own MLD address.
This commit does below for enabling MLO during external SAE
authentication:
- Use MLD addresses for SAE authentication.
- Add Basic Multi-Link element with the own MLD address in SAE
Authentication frames.
- Send SAE Authentication frames with the source address as the own MLD
address, destination address and BSSID as the AP MLD address to the
driver.
- Validate the MLD address indicated by the AP in SAE Authentication
frames against the AP MLD address indicated in external authentication
request.
- Store the PMKSA with the AP MLD address after completing SAE
authentication.

The initial MACsec implementation required the EAP Session-Id to be at
least 65 octets long and by truncating the value to that length, the
practical limit of functional cases was limited to that exact length of
65 octets. While that happens to work with EAP method that use TLS, it
does not work with most other EAP methods.
Remove the EAP Session-Id length constraint and allow any length of the
Session-Id as long as the EAP method provides one. In addition, simplify
this be removing the unnecessary copying of the Session Id into a new
allocated buffer.

While checking for stale BSSes, the current time is used as a basis and
then based on age the stale check time is calculated, but if this is
done too early in the boot and if either BOOTTIME/MONOTONIC (the one
Zephyr uses by default) are used then the stale check time underflows
and goes to future causing active BSS entries in the scan to be treated
as stale and flushed.

It was possible to hit a case where the SAE PT had not yet been derived,
e.g., when using P2P group re-invocation. Update PT use at the time
authentication is started, if needed, to avoid this. While this is not
really ideal from the externally observable timing view point, this is
done only for the case where there is no other option available with a
dynamically changing network configuration for P2P. Similar design was
already in place for the SAE offload-from-driver (external auth) case.

Both P2P GO and client always save key_mgmt = WPA_KEY_MGMT_PSK in the
configuration when storing a persistent group. Next time, when a GO is

to SAE and use hash-to-element mechanism, but the P2P client doesn't
change the parameter even if the group it wants to join is operating on
a 6 GHz channel. The P2P connection will be failed due to reason 'reject
due to mismatch with WPA/WPA2'.

When MAC address randomization settings change we should use a new MAC
address even if we are associating to the same ESS.
For example, consider this scenario:
- hardware MAC is being used,
- we disconnect from the network,
- policy/style is changed via D-Bus to turn randomization on,
- we reconnect to the same network.
In the last step a randomized MAC address should be used.
Changes to the randomization settings include both changes to the
policy/style to be used and changes to the pregenerated MAC address
value in case of mac_addr==3.

If the CreateInterface command was used to create a virtual AP
interface, deleting this interface using the RemoveInterface command was
also bringing down the primary interface.
wpa_supplicant never uses hostapd style multi-BSS setup with
type=WPA_IF_AP_BSS and setup_ap=1 to if_add() when creating an AP
interface in wpa_driver_nl80211_if_add(), so it should not go through
the multi-BSS tear down procedure in wpa_driver_nl80211_if_remove(). The
virtual AP resources init and deinit are well handled in
wpa_driver_nl80211_init() and wpa_driver_nl80211_deinit().

skip the multi-BSS cleanup procedure. This is inline with the control
interface design. Add comments before the code to avoid confusion.
