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.
