This patch removes redundant actions from driver and fixes its interaction with actions in pci-bus runtime power management code. It removes pci_save_state() from __e1000_shutdown() for normal adapters, PCI bus callbacks pci_pm_*() will do all this for us. Now __e1000_shutdown() switches to D3-state only quad-port adapters, because they needs quirk for clearing false-positive error from downsteam pci-e port. pci_save_state() now called after clearing bus-master bit, thus __e1000_resume() and e1000_io_slot_reset() must set it back after restoring configuration space. This patch set get_link_status before calling pm_runtime_put() in e1000_open() to allow e1000_idle() get real link status and schedule first runtime suspend. This patch also enables wakeup for device if management mode is enabled (like for WoL) as result pci_prepare_to_sleep() would setup wakeup without special actions like custom 'enable_wakeup' sign.
