  Tester                      Target
    |                           |

  1. Send Echo Request.
  2. Wait 5sec.

  Echo Request Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 24
            NextHeader         = 59 (None)
            SourceAddress      = Tester Link Local Address
            DestinationAddress = Target Link Local Address

        ICMP Echo Request
            Type           = 128 (Echo Request)
            Code           = 0
            Checksum       = (auto)
            Identifier     = 0xffff
            SequenceNumber = 1
            PayloadData    = {1, 2, 3, 4, 5, 6, 7, 8}


=head1 JUDGEMENT

  PASS: Not Receive any packets.

  FAIL: Received Echo Reply.


=cut

# =head1 REFERENCE
# 
# RFC2460
# 
# 4.7.  No Next Header
# 
# The value 59 in the Next Header field of an IPv6 header or any extension
# header indicates that there is nothing following that header.
# If the Payload Length field of the IPv6 header indicates the presence
# of octets past the end of a header whose Next Header field contains 59,
# those octets must be ignored, and passed on unchanged if the packet
# is forwarded.
