AsconfWithSetExists.seq - ASCONF chunk is received with Set Primary Address Parameter which contain a address part of the association
To check that if ASCONF chunk is received with Set Primary Address Parameter
which contain a address part of the association 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 A such that ASCONF chunk with Set Primary Address Parameter
which contain a address part of the association is sent to endpoint B.

TEST DESCRIPTION:
1. Send ASCONF chunk from endpoint A to B with Set Primary Address Parameter
which contain a address part of the association.
2. Check A: ASCONF-ACK with complete success should be received at endpoint
A and the 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.
