Subject: TCP Hook

Hi,

I am implementing a TCP option that changes TCP data. Changing the
length will affect CWND, segment splitting and sequence numbers. I'd
rather not redo all that work.

Is there any support for filtering at the kernel level, so I can hook
all TCP traffic without having to worry about re-framing?

Thanks,

Sam
