[Bug 82335] Re: network-manager should not set offline mode when it manages no device

[Jeff Fortin]

Yeah, that's why I call it a "workaround" "in some cases" and not a
solution :) not everyone has this kind of functionality available, but
those who do (and did not know that it existed) can use that as a
temporary measure until this bug is fixed.
