- moved away from ifn/ifa access to sctp_ifa/sctp_ifn built and managed by the add-ip code. - cleaned up add-ip code to use the iterator - made iterator be a thread, which enables auto-asconf now. - rewrote and cleaned up source address selection (also made it use new structures). - Fixed a couple of memory leaks. - DACK now settable as to how many packets to delay as well as time. - connectx() to latest socket API, new associd arg. - Fixed issue with revoking and loosing potential to send when we inflate the flight size. We now inflate the cwnd too and deflate it later when the revoked chunk is sent or acked. - Got rid of some temp debug code - src addr selection moved to a common file (sctp_output.c) - Support for simple VRF's (we have support for multi-vfr via compile switch that is scrubbed from BSD but we won't need multi-vrf until we first get VRF :-D) - Rest of mib work for address information now done - Limit number of addresses in INIT/INIT-ACK to a #def (30).
