I don't like this use of notifiers for several reasons:
1. It becomes harder to grep for users of this.
2. We lose documentation about what is passed for each method.
3. We lose const-ness for parameters, which then allows users to
modify phylink-internal data structures inappropriately from
these notifier calls.
Please find another way.
