  1. Send Test Packet (Unexpected Next Header in IPv6 Header)
  2. Wait ICMP Error or NS
  3. If NS received then send NA, and wait ICMP Error again
  4. Receive ICMP Error

  Test Packet to Target Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 16
            NextHeader         = 0 (Hop-by-Hop Options Header)
            SourceAddress      = Tester Address
            DestinationAddress = Target Address

        Fragment Header                      as HbH Options Header
            NextHeader      = 58 (ICMPv6)    <= Next Header
            Fragment Offset = 0              <= Option (Pad1)
            MFlag           = 0              <= Option (Pad1)
            Fragment ID     = 34560 (0x8700) <= Option (Undefined)

        ICMP Echo Request

JUDGEMENT

  PASS: ICMP Error Received

        IPv6 Header
            Version            = 6
            Traffic Class      = 0

            NextHeader         = 58 (ICMPv6)
            SourceAddress      = Target Address
            DestinationAddress = Tester Address

        ICMP Error
            Type           = 4 (Parameter Problem)
            Code           = 2 (unrecognized IPv6 Option encountered)
            Checksum       = (auto)
            Pointer        = 46 (Offset to Fragment ID in Fragment Header)
            PayloadData    = (Sent Packet)
