Yep, that does it. Simple. Elegant. I see now why my (bloated
unintelligible) patch worked, it also didn't reset the timer when a
delayed ack might have already been pending.
OK, there are other parts of the code that do the same thing
(TCP_REASS, SYN was ACKed, et. al.) but if no one objects, I'll
send-pr the patch to be commited.
Thanks everybody!!
