Routine Description:

    This routine is the receive event indication handler.

    It is called when an session packet arrives from the network. It calls
    a non OS specific routine to decide what to do.  That routine passes back
    either a RcvElement (buffer) or a client rcv handler to call.


Return Value:

    NTSTATUS - Status of receive operation
