- To invoke the API wlan_send_tid_to_link_mapping from other
files, change its static definition and add a function
declaration.
- Remove repetitive logging of T2LM params in
wlan_mlo_parse_t2lm_info API.
- HMT STA host needs to send T2LM mapping info to FW only
on one peer instead of both peers in case of WKK.
Thus, add new API under MCC flag to address this issue.

Non-assoc link might be superior in features compared to assoc
link and the per-STA profile info may carry corresponding IEs.
These IEs are extracted and added to IE list of link probe
response while generating it. So, the link probe response
generated from assoc link probe response might be of more size
than assoc link probe rsp. It's caller responsibility to allocate
buffer for the derived scan entry considering the copied IEs from
ML per STA profile.
Add a check to validate the available buffer while copying the
ML IE (as it's copied after deriving IEs from per STA profile) as
this is missing currently.

When mlo_connect is posted, mlo_dev_ctx lock is acquired.
As part of which is CM is not in init state, disconnection is posted

In case of ml_activate_pend_disconn_req_cb, mlo_disconnect is called
which validates disconnect request. If the disconnect was deferred due
to race in mlo connect notify event and disconnect received by mlo
manager, then ml_activate_pend_disconn_req_cb will end up in a deadloop
where it will always defer any disconnect due to above race.
Hence, add API with flag to validate disconnect request.

As per current design, dp_mlo_ctxt is allocated during the
initialization of module while the MLO grouping information is
understood after WMI_READY_EVENT. The same is deinitialized while
unregistering the module.
To ensure dp_mlo_ctxt exists per MLO group, bring the dp_handle
a layer below in the hierarchy into the mlo_setup_info and allocate
dp_mlo_ctxt after the WMI_READY_EVENT is received from all the SOCs
for a given group. Deallocate it after the WMI_MLO_TEARDOWN_COMPLETE
event is received.

To assist the Host in ML reconfiguration element construction for probe
responses, FW sends MLO link removal information as part of the MGMT Rx
event containing the corresponding probe request. This information is an

Currently, link vdev is triggered to connect process
after assoc vdev connects successfully in function
mlo_send_link_connect. If osif_cm_disconnect_sync is
invoked during assoc vdev connection, the disconnect
command for link vdev is dropped since it is in INIT
state. Then it only queues the disconnect command for
assoc vdev. After link vdev connects successfully, it
process the disconnect command for assoc vdev, and F/W
assert happens because deleting assoc peer before link
peer.
To resolve the issue, invoking wlan_cm_disconnect with
source CM_MLO_LINK_VDEV_DISCONNECT for each link vdev
in function cm_disconnect_start for assoc vdev.

In scenario where the last ML-AP vdev of the MLD receives start response,
then in the same context mlo_sync_complete is dispatched to all the
partner ML AP vdevs.
But for the partner vdevs, VDEV SM event should be dispatched in
non-sync mode with lock held. If not it can lead to event being
dispatched when the VDEV is in intermediate transition state.
For partner vdevs dispatch event as part of callback and based on return
value, dispatch event in sync context for self vdev.
This is to avoid usage of mlme vdev sm sync event dispatch outside VDEV SM

When vdev1 connected, if find vdev0 isn't connected, disconnect vdev1 in
