compile-tested only
With legacy PM hooks, it was the responsibility
of a driver to manage PCI states and also
device's power state. The generic approach is
to let PCI core handle the work.
PCI core passes "struct device*" as an argument
to the .suspend() and .resume() callbacks. As
these callabcks work with "struct net_device*",
extract it from "struct device*" using
dev_get_drv_data().
