Extra libraries is one of the least important points in my opinion,
I also guess pretty much anyone using a software device already has
iproute installed, which could easily support all of them.

The more important things to consider are in my opinion extendability
and atomicity of changes and dumps:

- ioctls: atomicity, not easily extendable
- sysfs: no atomicity, easily extendable
- procfs: if atomicity not easily extendable, but can of course also
  be used similar to sysfs

Only netlink offers both in an easy to use fashion and is already used
for the main parts of network configuration anyway.
