=head1 NAME

  ShutdownFromPeer.seq - Termination of an association by receiving SHUTDOWN message

=head1 PURPOSE

  To check that receiving Terminate primitive will cause the endpoint
  to send a SHUTDOWN message to its peer only when all the outstanding
  DATA has been acknowledged by A.

=head1 SYNOPSIS

=begin html
<PRE>
  <A HREF="./ShutdownFromPeer.seq">./ShutdownFromPeer.seq</A> [-tooloption ...] -pkt <A HREF="./ShutdownFromPeer.def">./ShutdownFromPeer.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 the data
  in endpoint B such that Terminate primitive is received from upper
  layers.

=head1 TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (ESTABLISHED)                        (ESTABLISHED)

   SHUTDOWN           -------------->

                      <---------------   SHUTDOWN-ACK

   SHUTDOWN-COMPLETE  --------------->   Association is removed
                                         Communication Lost  --------->

  TEST DESCRIPTION:

  1. Try to terminate an association between endpoint A and endpoint B by 
     sending Terminate primitive to endpoint B from ULP. Before sending 
     Terminate, send some data to endpoint A and don't send SACK for them 
     from A.
  2. Check A: SHUTDOWN message is sent to endpoint A.
  3. Check B: SHUTDOWN is sent only when any data queued up at B has been 
     sent to A and acknowledged by A.

=head1 NOTE

  None
