If set to 1, no ABORT is sent back in response to an incoming

an out of the blue packet. If set to 0 (the default), ABORTs
are sent.

e6194c2ed4 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.
