=head1 NAME

  PartialChunkNotAlign.seq - Partial Chunk is received with chunk length not 4-bytes alignment

=head1 PURPOSE

  To check that if partial chunk is received with chunk not 4-bytes
  alignment, the endpoint should drop the chunk.

=head1 SYNOPSIS

=begin html
<PRE>
  <A HREF="./PartialChunkNotAlign.seq">./PartialChunkNotAlign.seq</A> [-tooloption ...] -pkt <A HREF="./PartialChunkNotAlign.def">./PartialChunkNotAlign.def</A>
    -tooloption : v6eval tool option
  See Also: <A HREF="../common/STD_PKT_COMMON.def">../common/STD_PKT_COMMON.def</A>
            <A HREF="../common/SCTP_COMMON.def">../common/SCTP_COMMON.def</A>
</PRE>

=end html

=head1 PRE-TEST CONDITION

  Association is established between endpoint A and B. Arrange
  data in endpoint A such that DATA chunk is sent to endpoint
  B with chunk length not 4-bytes alignment.

=head1 TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (ESTABLISHED)                        (ESTABLISHED)

  DATA          ----------------->      Discard DATA
  (chunk length not 4-bytes alignment)

  TEST DESCRIPTION:

  1. Send DATA message from endpoint A to B with chunk length not 4-bytes
     alignment.
     Record the message sequence using a signal emulator.
  2. Check A: ABORT message is discarded and no other actions are taken. 
  3. Check B: Was the message sequence as above.

=head1 NOTE

  None

=head1 REFERENCE

  RFC 4960

  6.10.  Bundling

    Partial chunks MUST NOT be placed in an SCTP packet.  A partial chunk
    is a chunk that is not completely contained in the SCTP packet; i.e.,
    the SCTP packet is too short to contain all the bytes of the chunk as
    indicated by the chunk length.

=begin html
<PRE>
    An endpoint MUST process received chunks in their order in the
    packet.  The receiver uses the Chunk Length field to determine the
    end of a chunk and beginning of the next chunk taking account of the
    fact that all chunks end on a 4-byte boundary.  <B>If the receiver
    detects a partial chunk, it MUST drop the chunk.</B>
