I guess that's because noone ever bother to do this.

Why would you want that? And how should the result look like?

You should know that this is not an easy task: lwIP has not been written
for multiprocessing. In other words, unless using lwIP in a single
process only, you'd end up writing a *lot* of code. This can be done
(e.g. like lwIP has been included into Minix), but it's a lot of work.

I guess the easiest thing to do would be to disable TCP/IP support in
your kernel to make sure it doesn't implement IP at all. Then you can
just run lwIP in a single process, interfacing the network stack through
PF_PACKET sockets...

But the question remains: why would you want to do that?
