I'm not really convinced that udev should be in charge of network
config changes, it's a really complex area. Udev is a generic kernel
device manager, not a network setup manager.

Our point of view is, that all services depending on network state
changes should listen to netlink themselves, and not be worked around
with tools like udev to execute stuff and notify them.

But again, what's the use-case for that you have in mind?
