This way the problem is that I have to know which devices I will
add the attributes. But the point is to add attributes to
all netdevs.

Using this approach I'd have to enumerate all the interfaces every
now and then.

If I have my class interface I get a callback whenever an
interface is created or deleted and I can automatically add the
attribute to all netdevs.
