[...]
> I noticed that one of the post-2.6.36 patches broke runtime PM of the
> r8169 on my MSI Wind test machine in such a way that the link was not
> brought up after reconnecting the network cable.
>
> In the process of debugging the issue I realized that we only should
> invoke the runtime PM functions in rtl8169_check_link_status() when
> link change is reported and if we do so, the problem goes away.
> Moreover, this allows rtl8169_runtime_idle() to be simplified quite
