Comment 201 for bug 191889

The summary doesn't really reflect the current solution, and I think that while a preference would help as a workaround, it isn't really a solution (the solution is that we should make sure we're getting the right signals for the OS).

So I spun out bug 437453 for adding a preference for turning on/off automatic online/offline. Let's keep working on Linux/NM specific solutions here, and the workaround there.
