A couple of years ago I helped Niels Provos port our Berkeley Daedalus
project SACK/FACK/NewReno code (for BSDi) to OpenBSD.  I did contribute the
newreno piece originally to the Berkeley code.
(ftp://daedalus.cs.berkeley.edu/pub/tcpsack/bsdi-3.0)  Someone ported that
newreno code into freebsd (looks like 1.107.2.6 on tcp_input.c-- jlemon) but
not the sack code.

My question was due to the fact that the proposed patch diverged from the
NewReno RFC and Berkeley code-- I was curious to find out why and what
problems people found to motivate that patch.
