Agreed, one process, one control path socket.

FWIW the rtnetlink use of netlink is very basic. genetlink already has
some infra which allows associate state with a user socket and cleaning
it up when the socket gets closed. This needs some improvements. A bit
of a chicken and egg problem, I can't make the improvements until there
are families making use of it, and nobody will make use of it until
it's in tree... But the basics are already in place and I can help with
building it out.
