#1257 proposes to add support for attaching netkit programs, but we don't want to take on a dependency to vishvananda/netlink, even for testing. We've decided to drop the netkit tests for now, since the patchset is small and largely based on existing code, and kernel support isn't shipping in major distros for a while.

This issue is for 2 things:

• add netkit support to https://github.com/jsimonetti/rtnetlink
• add tests for the behaviour introduced in Add support for netkit device #1257
