The structure of the controllers is really similar to addresses and routes: * `LinkSpec` resource describes desired link state * `LinkConfig` controller generates `LinkSpecs` based on machine configuration and kernel cmdline * `LinkMerge` controller merges multiple configuration sources into a single `LinkSpec` paying attention to the config layer priority * `LinkSpec` controller applies the specs to the kernel state Controller `LinkStatus` (which was implemented before) watches the kernel state and publishes current link status.
