    NET/r8169: Rework suspend and resume · 861ab440
    Rafael J. Wysocki authored
    The recent changes of the PCI PM core allow us to simplify the
    suspend and resume handling in a number of device drivers, since they
    don't need to carry out the general PCI PM operations, such as
    changing the power state of the device, during suspend and resume any
    more.
    
    Simplify the suspend and resume callbacks of r8169 using the
    observation that the PCI PM core can take care of some operations
    carried out by the driver.
    
    Additionally, make the shutdown callback of r8169 only put the device
    into a low power state if the system is going to be powered off
    (kexec is known to have problems with network adapters that are put
    into low power states on shutdown).
    
    This patch has been tested on MSI Wind U100.
