Hi, The following two patches add basic PCI runtime power management to the r8169 and e1000e drivers. It works so that the adapter is put into PCI D3 if there's no network cable attached to it and back into PCI D0 once the cable has been detected. The feature is disabled by default and it can be enabled by writing "auto" to the device's /sys/devices/.../power/control file. Writing "on" to this file disables the feature again. The patches have been tested on MSI Wind U100 (r8169) and Toshiba Portege R500 (e1000e).
