No, you don't. Forget it. A full-blown  TCP/IP  stack  requires  much
more  services  than  avialable  in  U-Boot.  Please repeat after me:
U-Boot is just a boot loader, it is NOT an operating system.

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 ;-)

Short answer: yes.

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.
