A full-blown TCP/IP stack requires much more services than avialable in U-Boot.

Then boot a minimized Linux kernel first. Or, if this is not allowed by your Powers That Be, then boot a NetBSD image for this task ;-) > Is it so difficult to embed tcp in u-boot?

Then do yourself a favour and reject this job. All your work would be wasted. It makes NO, absolutely NO sense to base current work (especially work that is intended to add major extensions) on old code that has been obsoleted more than a year ago.
