AsconfAckWithZeroParamLen.seq - ASCONF-ACK chunk is received with parameter length set to zero
To check if ASCONF-ACK chunk is received with parameter length set to
zero, the receiver MUST send ABORT with the error cause set to the
error code 'Protocol Violation'.

Association is established between endpoint A and B. Arrange the data
in endpoint A such that ASCONF-ACK chunk with parameter length set to
zero is sent to endpoint B.

TEST DESCRIPTION:
1. Send ASCONF-ACK chunk from endpoint A to B with parameter length
set to zero.
2. Check A: ABORT with error code 'Protocol Violation' should be
received at endpoint A.

4.1.2. Address Configuration Acknowledgment Chunk (ASCONF-ACK)
This chunk is used by the receiver of an ASCONF Chunk to acknowledge
the reception. It carries zero or more results for any ASCONF
parameters that were processed by the receiver. This chunk MUST be
sent in an authenticated way by using the mechanism defined in
[RFC4895]. If this chunk is received unauthenticated it MUST be
silently discarded as described in [RFC4895].

Sequence Number: 32 bits (unsigned integer)
This value represents the Sequence Number for the received ASCONF
Chunk that is acknowledged by this chunk. This value is copied from
the received ASCONF Chunk.
ASCONF Parameter Response: TLV format
The ASCONF Parameter Response is used in the ASCONF-ACK to report the
status of ASCONF processing. By default, if a responding endpoint
does not include any Error Cause, a success is indicated. Thus a
sender of an ASCONF-ACK MAY indicate complete success of all TLVs in
an ASCONF by returning only the Chunk Type, Chunk Flags, Chunk Length
(set to 8), and the Sequence Number.
