An affiliated AP of an AP MLD can temporarily be disabled. Other
affiliated APs of the AP MLD indicate this in the Reduced Neighbor
Report (RNR) elements added to their Beacon and Probe Response frames.
When an affiliated AP is disabled, it should be included in the
association exchange, but can be activated only after it is enabled.
Add support identifying disabled APs and propagate the information
to the driver within the associate() callback.

Use AP MLD address instead of BSSID for PWE derivation during MLO
connection. This was already done for H2E in commit e869fdfeef
("wpa_supplicant: Use MLD address in SAE authentication"). While IEEE
P802.11be requires H2E to be used, there are deployed AP MLDs that do
not follow that requirement. This change to the hunting-and-pecking loop
case is needed for interoperability workarounds with such APs.

For wpa_supplicant based SAE/OWE connection, the wpa_supplicant state
machine is aware of the PMKID created for a connection and this gets
removed when "REMOVE_NETWORK all" is called. However, when SAE/OWE

The wpa_auth_callbacks for mesh was missing a for_each_sta
implementation. This is an issue with pmksa cache, as when a cache entry
expires the for_each_sta callback is called in order to clear the pmksa
reference for all sta that was using this entry. Not having a
for_each_sta callback will prevent this cleanup to happen then a sta
could still use this pmksa entry even after it has been freed.
This used after free was not a problem up until recently where
dpp_pkhash is now stored in pmksa entry and retreived later on causing

When connecting, pending_bssid is set to the main link that we are
authenticating/associating on. Later on, the MLD MAC address will be
stored in the bssid, but we may also try to deauthenticate before we are
connected and in that case, pending_bssid is not yet set to the MLD MAC
address.
As such, use the ap_mld_addr instead of pending_bssid if n_mld_links is

BSS table is not updated when a non-P2P station runs a scan without P2P
IE in Probe Response frame, since that would remove P2P IE information.
However, this results also in not updating mandatory rates in Supported
Rates and BSS Membership Selectors element even though AP/GO changes
frequency from 2.4 GHz to 5 GHz band.
This is causing connection failure since BSS table has 1 Mbps as
mandatory rate for AP connection but minimum supported rate in 5 GHz
band is 6 Mbps.
To avoid connection failures in such cases, don't skip updating BSS
table when the BSS frequency is changed. This covers the most important
case addressed in commit ff57398fca ("P2P: Do not drop P2P IEs from
BSS table on non-P2P scans") while still allowing other changes to be
taken into account if the GO were to actually change channels (or band,
which would be the most likely case needing the update).
