Hi Jiri
Is that really going to happen? register_netdevice_notifier() is used
in 130 files. Do you plan to spend the time to make it happen?

Humm. I wonder about NOTIFY_STOP_MASK here. These are two separate
chains. Should one chain be able to stop the other chain? Are there
other examples where NOTIFY_STOP_MASK crosses a chain boundary?
