Well, I decided to use the ipfilter 3.4.35 that comes with FreeBSD
5.3, and wasn't sure whether the window scaling bug had already been
fixed in 3.4.35, or if your patch against 3.4.33 needed modification.
Could you please take a look at ipfilter 3.4.35 and let me know if
your patch still applies?

AFAIK that has been fixed in ipfilter 3.4.35.

Ask the people who requested Atheros support... Maybe it's time to
submit the window scaling patch to Darren Reed so it can be included
in ipfilter 3.4.36 (or at least to the FreeBSD project, given that
ipfilter 3.4.35 is the version that comes with 5.3).
