AsconfAckWithSetSuccess.seq - ASCONF-ACK chunk is received with Success Indication parameter indicating Set Primary Address success
To check that if ASCONF-ACK chunk is received with Success Indication
parameter indicating Set Primary Address success then the endpoint should
mark the specified address as the primary address to send data to.

Association is established between endpoint A and B. Arrange the date
in endpoint B such that ASCONF chunk with Set Primary Address Parameter
is sent to endpoint A.

TEST DESCRIPTION:
1. Sending ASCONF message with Set Primary Address Parameter from
endpoint B to A.
Record the message sequence using a signal emulator.
2. Send ASCONF-ACK message with Success Indication parameter
indicating Set Primary Address success from endpoint A to B.
3. Check A: Endpoint B should mark the specified address as the
primary address to send data to.

ASCONF-Request Correlation ID: 32 bits
This is an opaque integer assigned by the sender to identify each
request parameter. The receiver of the ASCONF Chunk will copy this
32-bit value into the ASCONF Response Correlation ID field of the
ASCONF-ACK response parameter. The sender of the ASCONF can use this
same value in the ASCONF-ACK to find which request the response is
for. Note that the receiver MUST NOT change this 32-bit value.
Address Parameter: TLV
This field contains an IPv4 or IPv6 address parameter as described in
Section 3.3.2.1 of [RFC4960]. The complete TLV is wrapped within
this parameter. It requests the receiver to mark the specified
address as the primary address to send data to (see Section 5.1.2 of
[RFC4960]). The receiver MAY mark this as its primary address upon
receiving this request. If the address 0.0.0.0 or ::0 is provided,
the receiver MAY mark the source address of the packet as its
primary.
