Currently stop is being called unconditionally without even checking if start is called. In case of multiple instances eth being present many devices might just be initialized without a start call in such cases stop might lead unpredictable behaviors including aborts and crashes. Hence add a check before calling stop.

This seems reasonable... What was the case that provoked an issue? Which driver was having trouble?
