NAME

  FutureSACKNotSend.seq - SACK containing Cumulative TSN greater than the Cumulative TSN Ack point (NO DATA with that TSN has been send)

PURPOSE

  To check that SACK received from a destination address corresponding to 
  which there is no DATA with that TSN has been send, the endpoint should
  response with ABORT.

SYNOPSIS

  ./FutureSACKNotSend.seq [-tooloption ...] -pkt ./FutureSACKNotSend.def
    -tooloption : v6eval tool option

PRE-TEST CONDITION

  Association is established between endpoint A and B. Arrange data 
  in endpoint A such that SACK with future TSN is sent to endpoint B.

TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (ESTABLISHED)                        (ESTABLISHED)

                                                   <-----    Send
                <-----------------      DATA

  SACK          ----------------->

  SACK          ----------------->
  (With future TSN)
                <-----------------      ABORT

  TEST DESCRIPTION:

  1. From endpoint A, send valid SACK message to endpoint B, when there
     is no DATA with that TSN has been send between them. 
  2. Check A: ABORT message will be sent and SACK is discarded.
