=head1 NAME

    IP_NH_Unrecoginzed - Unrecognized Next Header in IPv6 Header (Multiple Values)

=head1 TARGET

    Host and Router

=head1 SYNOPSIS

=begin html
    <PRE>
    <A HREF="./IP_NH_Unrecoginzed.seq">IP_NH_Unrecoginzed.seq</A> [-tooloption ...] -pkt <A HREF="./IP_NH_Unrecoginzed.def">IP_NH_Unrecoginzed.def</A>
        -tooloption: v6eval tool option
    </PRE>

=end html

=head1 INITIALIZATION

    None

=head1 TEST PROCEDURE

    1. Send a packet which has Next Header 0.
    2. Wait ICMPv6 Parameter Problem or NS
    3. If NS received then send NA, and wait ICMPv6 Parameter Problem again
    4. Send Echo Request
    5. Wait Echo Reply or NS
    6. If NS received then send NA, and wait Echo Reply again
    7. Receive Echo Reply
    8. repeat from 1 to 7 (with increment Next Header value up to 255).

    last Unrecognized Next Header packet is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 16
            NextHeader         = 138 - 252 (be increased for each packets.)
            HopLimit           = 255
            SourceAddress      = Tester Link Local Address
            DestinationAddress = Target Link Local Address

=head1 JUDGEMENT

    PASS : received Echo Reply packet.
    FAIL : don't received Echo Reply packet.
