ErrorInCookieWait.seq - ERROR chunk is received in COOKIE-WAIT state
To check that if ERROR chunk is received in COOKIE-WAIT state then the
endpoint should discarded the ERROR chunk.
./ErrorInCookieWait.seq [-tooloption ...] -pkt ./ErrorInCookieWait.def

Association not established between endpoint A and B. Also arrange the
data in endpoint B such that upper layers send Associate primitive to
startup an association with endpoint A.

TEST DESCRIPTION:
1. Attempt to make an association from endpoint B to endpoint A. Send
ERROR message after receiving INIT message.
2. Check A: ERROR message received in COOKIE-WAIT state is discarded.
3. Check B: Current state is not disturbed and an association can be
completed between A and B.

RFC 4960
3.3.10. Operation Error (ERROR) (9)
An endpoint sends this chunk to its peer endpoint to notify it of
certain error conditions. It contains one or more error causes. An
Operation Error is not considered fatal in and of itself, but may be
used with an ABORT chunk to report a fatal condition. It has the
following parameters:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

Chunk Flags: 8 bits
Set to 0 on transmit and ignored on receipt.
Length: 16 bits (unsigned integer)
Set to the size of the chunk in bytes, including the chunk header
and all the Error Cause fields present.
