        respond to the sender of the OOTB packet with a SHUTDOWN
        COMPLETE.  When sending the SHUTDOWN COMPLETE, the receiver of
        the OOTB packet must fill in the Verification Tag field of the
        outbound packet with the Verification Tag received in the
        SHUTDOWN ACK and set the T bit in the Chunk Flags to indicate
        that the Verification Tag is reflected.  Otherwise,</B>

    6)  If the packet contains a SHUTDOWN COMPLETE chunk, the receiver
        should silently discard the packet and take no further action.
