This test has been broken for a while. It tested:
- adding a listener triggers an interface state changed callback and an
ethernet state changed callback.
- setEthernetEnabled calls back the correct listeners and removes / adds
the interface.
Interface state listeners are already well covered in
EthernetManagerTest. I am currently working on adding tests for
setEthernetEnabled (there is partial coverage in setUp and tearDown of
EthernetManagerTest).
