re does not appear to be used so I think we can remove it.

Done.

GetEthernet returns nothing. You don't need _ethernet here.

We have a subroutine for this in pyauto.py.  It's called WaitUntil.  Look at
WaitUntilWifiNetworkAvailable in pyautolib/chromeos_network.py for an example of
this being used.
