FreeBSD 4.11-RELEASE & SACK

I've installed the standard FreeBSD 4.11-RELEASE and have realized that
the sysctl option for enabling SACK in TCP is not available
(net.inet.tcp.do_sack). Additionally, the tcp_sack.c file is not in the
/usr/src/sys/netinet so I'm guessing this indicates that I need a patch.
Hoping to be able to use SACK in FreeBSD 4.11-RELEASE, I wanted to ask :
1) Is my guess correct (Do I need a patch)? Or is my kernel configuration
file missing an option?
2) Assuming I need a patch, what patch is generally recommended for using
SACK under TCP in FreeBSD 4.11-RELEASE?
Any help would be most appreciated. Thanks,
