So far we don't re-configure WOL-related register bits when waking up from hibernation. I'm not aware of any problem reports, but better play safe and call __rtl8169_set_wol() in the resume() path too. To achieve this move calling __rtl8169_set_wol() to rtl8169_net_resume() and rename the function to rtl8169_runtime_resume().
