Subject: Re: Force ACK each received tcp segment under no condition

I tried 'TCP_QUICKACK' with libhttpd.c in thttpd, seems no effect,
that is why I want to go to the extreme route to make it in kernel to
do that always, there is really no good reason for this, I just want
to test the effect of ACK each segment under no condition in my
personal lab for some effect i am looking for.
