A new version of the patchset that is adapted to our latest -CURRENT code can be found at: http://research.delphij.net/freebsd/rfc3522.diff and http://people.freebsd.org/~delphij/for_review/rfc3522.diff Note that this version has not mixed with the Early Retransmission change as found in DragonFly.
