Xenomai is a real-time extension to the Linux kernel offering
deteministic services.
RTnet is a network stack, containing several drivers, offering
deterministic TCP/IP services. As such, it requires something providing
deterministic services. This something may be Xenomai or RTAI.
We could build another deterministic TCP/IP stack over Xenomai, but what
for? Since RTnet does that.
The fact that RTnet is not integrated into Xenomai is just the result of
history. And maybe the fact that we always had other things to do than
to integrate it into Xenomai codebase.
