The current roam sync propagation for LFR3.0 in the host driver is
based on queuing and message processing mechanism. This can lead
to many unknown sequence of operations as there might be other
messages sitting in the queue which may interrupt with this
operation. Hence, it would be good to introduce a callback mechanism
which take care of running the code to execution completely in case
of roam synch propagation.
It also improves to reduce the roam delay by 50 percent as compared
to the existing mechanism.
