Plans aren't concrete yet, but renovation (or replacement) of RTnet is
needed, specifically to support TSN. Ideally, we do that with maximum
reuse of kernel infrastructure, "just" adding the fast-path access from
an RT application. Or we look into reusing DPDK which is gaining TSN
support as well and has a Linux-free data path already.
