All:
Does FreeBSD-stable (3.1) support SACK.
If not, will it be available in future releases?
There is no sysctl.net.tcp.sack parameter.
Searching on the mailing list archives indicate that experimental
patches were available in 1996.
Another person found some experiment options in the kernel.
Since we would like to start using SACK only if it is supported in
a stable release.
I use "3.1-RELEASE FreeBSD 3.1-RELEASE #0: Mon Feb 15 11:08:08 GMT 1999
jkh@usw3.freebsd.org:/usr/src/sys/compile/GENERIC i386"
Searching the Handbook and the Web Site did not yield any results.
Please let me know.
Thanks.
Hui

Luigi Rizzo has SACK/TSACK patches for 2.1.6 at
It looks like there is/was another implementation of SACK onto 2.1.6;
http://irl.cs.ucla.edu/sack.html says that part of its testbed was
2.1.6 machines.

/usr/src/sys/netinet/tcp.h contains an option TCPOPT_SACK, and it says
it's experimental.
