It's more heavily needed for pasta because, there, we use it to
directly configure the networking in the container (with --config-net),
whereas with passt the configuration happens via DHCP/NDP/DHCPv6.

With passt, we use netlink just to source addresses and routes from the
host. I see two alternatives for Darwin:

- use sysctls with NET_RT_DUMP / NET_RT_IFLIST2 / NET_RT_DUMP2 to fetch
  the same information. It's not clear to me if it needs root, though,
  or if there's a different way to fetch information without root

- force the user to give a manual configuration (with options -a, -g at
  least)
