Ok, so we probably won't focus on b) as a priority right now, unless
it happens as a side-effect.

Good! At the moment I'm looking at various netlink docs and figuring
out how things generally work. I think netlink probably adds a lot of
complexity over the previous sockopt interface, but I hope it's worth

As for compatibility and extensibility, how is that best achieved with
netlink? I've seen some examples copy whole C structs into netlink
datagrams, but that is obviously what we don't want anymore. So the
way to go seems to be to transfer each struct field as a separate
netlink attribute, right?
