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

d77e2e42b3 Fix a bug in the way ECN-Echo chunk
sends were being accounted for. The
counting was such that we counted only
when we queued a chunk, not when we sent it.

one for sending.

8933fa13b6 Many bug fixes (from the IETF hack-fest):
- PR-SCTP had major issues when skipping through a multi-part message.
  o Did not look at socket buffer.
  o Did not properly handle the reassmebly queue.
  o The MARKED segments could interfere and un-skip a chunk causing
    a problem with the proper FWD-TSN.
  o No FR of FWD-TSN's was being done.
- NR-Sack code was basically disabled. It needed fixes that
  never got into the real code.
- CMT code had issues when the two paths were NOT the same b/w. We
  found a few small bugs, but also the critcal one here was not
  dividing the rwnd amongst the paths.

a99b67833a - Cleanup checksum code.
- Prepare for CRC offloading, add MIB counters (RS/MT).
- Bugfix: Disable CRC computation for IPv6 addresses with local scope (MT).
- Bugfix: Handle close() with SO_LINGER correctly when notifications
          are generated during the close() call(MT).
- Bugfix: Generate DRY event when sender is dry during subscription.
          Only for 1-to-1 style sockets (RS/MT)
- Bugfix: Put vtags for the correct amount of time into time-wait (MT).
- Bugfix: Clear vtag entries correctly on expiration (MT).
- Bugfix: shutdown() indicates ENOTCONN when called for unconnected
          1-to-1 style sockets (MT).
- Bugfix: In sctp Auth code (PL).
- Add support for devices that support SCTP csum offload (igb).

830d754d52 Code from the hack-session known as the IETF (and a
bit of debugging afterwards):
- Fix protection code for notification generation.
- Decouple associd from vtag
- Allow vtags to have less strigent requirements in non-uniqueness.
   o don't pre-hash them when you issue one in a cookie.
   o Allow duplicates and use addresses and ports to
     discriminate amongst the duplicates during lookup.
- Add support for the NAT draft draft-ietf-behave-sctpnat-00, this
  is still experimental and needs more extensive testing with the
  Jason Butt ipfw changes.
- Support for the SENDER_DRY event to get DTLS in OpenSSL working
  with a set of patches from Michael Tuexen (hopefully heading to OpenSSL soon).
- Update the support of SCTP-AUTH by Peter Lei.
- Use macros for refcounting.
- Fix MTU for UDP encapsulation.
- Fix reporting back of unsent data.
- Update assoc send counter handling to be consistent with endpoint sent counter.
- Fix a bug in PR-SCTP.
- Fix so we only send another FWD-TSN when a SACK arrives IF and only
  if the adv-peer-ack point progressed. However we still make sure
  a timer is running if we do have an adv_peer_ack point.
- Fix PR-SCTP bug where chunks were retransmitted if they are sent
  unreliable but not abandoned yet.
