  1. Send Echo Request (1st fragment)
  2. Wait ICMP Error for 65 seconds
     If NS received then send NA, and wait ICMP Error again
  3. Receive ICMP Error

  Echo Request Data (original) is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0

            SourceAddress      = Tester Link-local Address
            DestinationAddress = Target Link-local Address

        ICMP Echo Request

                             data repeat{0x2, 40}

  Echo Request Data (1st fragment) is:

            Version            = 6
            Traffic Class      = 0

            DestinationAddress = Target Link-local Address

        Fragment Header
            NextHeader         = 58 (ICMPv6)
            FragmentOffset     = 0

            Type           = 3 (Time Exceeded)
