The logical link confirm callback is executed when the AMP controller
completes its logical link setup. During a channel move, a newly
formed logical link allows a move responder to send a move channel
response. A move initiator will send a move channel confirm. A
failed logical link will end the channel move and send an appropriate
response or confirm command indicating a failure.
If the channel is being created on an AMP controller, L2CAP
configuration is completed after the logical link is set up.

received when the remote address is still setting up a physical link,

Two new states are required to implement channel moves with the ERTM
receive state machine.
The "WAIT_P" state is used by a move responder to wait for a "poll"
flag after a move is completed (success or failure). "WAIT_F" is
similarly used by a move initiator to wait for a "final" flag when the
move is completing. In either state, the reqseq value in the
poll/final frame tells the state machine exactly which frame should be
expected next.
