lucien 7c5a946181 sctp: ASCONF-ACK with Unresolvable Address should be sent
RFC 5061:
    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].

ASCONF chunk with Error Cause Indication Parameter (Unresolvable Address)
should be sent if the Delete IP Address is not part of the association.

  Endpoint A                           Endpoint B
  (ESTABLISHED)                        (ESTABLISHED)

                                        (Unresolvable Address)
