InitAckWithSmallArwnd.seq - INIT-ACK chunk is received with advertised receiver window less than 1500
To check that if INIT-ACK chunk is received with advertised receiver window
credit less than 1500, the endpoint should responded it with ABORT chunk
including cause of invalid mandatory parameter.

TEST DESCRIPTION:
1. Attempt to make an association from endpoint A to endpoint B. Send
INIT-ACK message with Advertised Receiver Window Credit less than 1500.
Record the message sequence using a signal emulator.
2. Check A: INIT-ACK message is responded with ABORT including cause of
invalid mandatory parameter.

6. User Data Transfer
An SCTP receiver MUST be able to receive a minimum of 1500 bytes in
one SCTP packet. This means that an SCTP endpoint MUST NOT indicate
less than 1500 bytes in its initial a_rwnd sent in the INIT or INIT
ACK.
