| [netdrvr] forcedeth: setup wake-on-lan before shutting down
|
| When hibernating in 'shutdown' mode, after saving the image the suspend hook
| is not called again.
| However, if the device is in promiscous mode, wake-on-lan will not work.
| This adds a shutdown hook to setup wake-on-lan before the final shutdown.

my servers with nvidia mcp55 will nic doesn't work with msi.
after remove pci_set_power_state(, PCI_D3hot) that nic/msi will work again.
check with e1000 is using pci_choose_state in _shutdown.
So change that pci_choose_state(pdev, ...), and it works.
