This mailing list discusses lwIP, not uIP.

If you get pissed by open-source materiale, my suggestion is to
piss back harder, just not on a public mailing list.

You suggest there is a single "you" here, while in fact, many people are
listening who have no clue what you are talking about or have anything 
to do with the documentation or samples you talk about.

There might be many reasons why your headers are not what they should 
be, including numerous faults on your behalf.

Please try somewhere else (/appropriate) and be a little more constructive.
