Hi all,

the problem with SCTP-IPv6 handling on FreeBSD, which appeared in
sctplib-1.0.0-pre11, unfortunately is still present in sctplib-1.0.0-pre12.

In detail:
When receiving an INIT message, an ABORT is returned. The SCTP Instance with
the destination address/port given in the INIT message is not found, even
though it has been registered before.

Below is the trace output. Note that in contrast to sctplib-1.0.0-pre11, the
destination address is now printed out correctly by mdi_receiveMessage.

Cheers,
Martin
