New Revision: 221249
URL: http://svn.freebsd.org/changeset/base/221249
Log:
Improve compilation of SCTP code without INET support.
Some bugs where fixed while doing this:
* ASCONF-ACK messages might use wrong port number when using
IPv6.
* Checking for additional addresses takes the correct address
into account and also does not do more comparisons than
necessary.
This patch is based on one received from bz@ who was
sponsored by The FreeBSD Foundation and iXsystems.
