FreeBSD 4.11-RELEASE & SACK

I posted this question on freebsd-question list yesterday, but no replies.
So I am just trying my luck here. Thanks in advance.
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,
