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.

f79aab1866 Tunes and fixes the new DC-CC to seem to hit the
right mix.  Still may need some tweaks but it
appears to almost not give away too much to an
RFC2581 flow, but can really minimize the amount of
buffers used in the net.

299108c5a2 Improvements to CC modules:
1) Add four new points that allow you to get more information
   to cc algo's
2) Fix the case where user changes module on a existing TCB, in
   such a case, the initialization module needs to be called on all nets.
3) Move htcp_cc structure to a union that other modules can use.
4) Add 5th point for get/set socket options for cc_module specific options
