If the scan entries for a non-tx profile MBSSID partner links
are not present at the time of candidate selection, then
host driver generates the scan entry for the missing partner
link from the assoc response.
The assoc response from the AP has PMKID in the RSN(some APs
do not include RSN IE in assoc resp).In this case, the RSN
along with PMKID gets inherited into the scan cache of the
missing partner and this leads to mismatch between M3 and
scan entry RSN causing disconnection.
To fix this, mark all the MBSSID partners without scan entries
as invalid links at the time of candidate shortlisting. Score
and connect to only non-tx candidates with valid scan entries.
Remove the probe response generation from assoc response logic.

Each link in MLO can have different RSN capabilities with
different AKMs, PMF capability, UC/MC cipher suites and so on.
For any choice of links for MLO connection, the AKMs of the

Modify partner link AKM to match assoc link AKM, so that
only overlapping AKM is chosen even though an AKM with

Wireless environment may have APs with same BSSID but different
MLD address and if any APs BSSID is similar to the current
candidates affiliated partner link BSSID, then receiving beacon
or probe resp from such APs will override the affiliated link's
scan entry and the MLD address may be different or NULL if the
AP is non-ML.
If link VDEV connection starts and during candidate selection
it may find the scan entry of this other AP and attempt to drive
connection will lead to creating ML link VDEV's peer with
different MLD address than assoc VDEV's peer.
Enhance scan filter to match MLD address for link VDEV to avoid

For multi link connection there might be the case where
rsnxe of the AP is not present on the link vdev.
This causes the link vdev alone to downgrade to 11ax
mode and assoc vdev is in 11be dot11 mode.
So for vdev with ML peer, the dot11mode is 11ax,
which causes abnormal firmware behavior.
Reject the partner link that doesn’t pass the security
check and validate the next available partner link.
if none of the partner link passes the security check,
