Introduce following for link switch disconnect:
1) Connect request source.
2) Connect request reason.
If the set MAC address response for new link is successful, post
connection on new link and transition the link switch state to
connecting. If the status of connection is successful, update
the state to link switch complete or else directly go for
deserializing link switch command and posting response to FW.
Based on the final state of link switch at the time of sending
FW response, send the appropirate status of link switch and reset
the state of link switch to idle post FW notify.
Don't unlink BSS incase of failure in connection.
Don't indicate connect results to userspace.
As we are already in serialization due to link switch,
don't serialize/deserialize connection command if it
is due to link switch.
Incase of race condition between link switch connect and
userspace connect/disconnect always abort link switch connect.

After receiving link switch disconnect completion indication
from connection manager, update the VDEV's MAC address to new
link's address to support link specific OTA frames exchange.
Introduce new dispatcher API to call from VDEV MLME, if the
VDEV for which MAC address response received is in link
switch in progress, then deliver the response to MLO mgr,
or else deliver it directly to OSIF.
Handle the FW response for link switch set MAC address in
MLO manager and if the set MAC addr response is successful,
update OSIF about the new MAC address to perform cleanup on
old link and initialize fields in new link.
If the response is successful, transition the link switch to
initiate connection or else abort link switch.

Introduce following for link switch disconnect:
1) Disconnect source.
2) Disconnect reason.
3) Link switch BIT in CM_ID to identify link switch request
Don't notify link switch disconnect to initiate disconnect on
other connect VDEV of MLO mgr.
Don't notify userspace if the disconnect request is due to
link switch.
Don't notify netdev to stop queues on link switch disconnect.
Don't flush any pending disconnect/connect request on complete
of link switch disconnect request.
Don't attempt to serialize/deserialize disconnect command
if it is a link switch command ID due to either disconnect request,
disconnect complete or disconnect request flush.
Before start of link switch set the VDEV flag as MLO link VDEV
to leverage the disconnect/connect checks for link VDEV and
restore the flag at the end of link switch. This will impact
when link switch on assoc VDEV is received for which initially
the flag is not set.
Check status of link switch disconnect done API to either
proceed further in link switch or terminate the link switch.
If any userspace disconnect and link switch disconnect race
condition, always abort link switch disconnect and notify
failure to FW.

Once the FW sends the link switch request to host handle
the request from scheduler thread and send confirmation
back on completion of link switch process with status of
link switch (success/failure).
Add new serialization command type for link switch.
Introduce flags to get the current state of link switch
request, set the state to idle when no link switch in
progress or once the current link switch is completed.
Access to state is protected with MLO dev context lock.
Implement various helper API to:
a) Transition link switch to next state.
b) Get current state of link switch.
c) To check whether any link switch is in progress.
c) To check whether link switch is happening
on assoc VDEV or not.
Introduce a new VDEV flag to suggest the VDEV is in
link switch process and also implement helper APIs to
set/get/clear this VDEV flag.
a) The flag is set at start of link switch, once
the FW request params are validated and before
proceeding for link switch disconnect on VDEV.
b) Clear the flag once the Link switch confirmation
is sent to FW.
Validate the link switch request params:
a) IEEE link ID's received.
b) Check if new connection is part of MLO connection.
c) Check if VDEV is MLO STA VDEV or not.
d) Is VDEV in connected state or not, that means
VDEV is not in transitioning state due to disconnect.
e) Check if any link switch in progress on this MLD
f) Current link ID of VDEV equals the FW params.
If validation is successful, serialize the link switch
command and in the serialization activation start the
actual link switch process.

Notify OSIF about each connected link once assoc VDEV connection
is completed, call the ops callback registered while filling

Add force flag support for PTQM migration.
This flag will be used to allow migration to vdevs which are not
allowed to be selected as primary by using the ini config.
This will be helpful in scenarios where if the current primary link is
going down and peer ptqm needs to be migrated but the partner links of
that mld are the user disabled links for ptqm.
Also add skip_pumac_cnt to mark a link to be skipped from being selected
as new primary
