Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.

When Phy has completed CCA, it calls back here which in turn execute the final steps of the CSMA-CA algorithm. It checks to see if the Channel is idle, if so check the Contention window before permitting transmission (step 5). If channel is busy, either backoff and perform CCA again or treat as channel access failure (step 4).
