This series patch add a fake driver r816e to ensure the kernel could 
set the correct power state for #fun through r816e driver when suspending.

I think a better approach would be to contribute to adding phylink/sfp support
to r8169, so that the SFP NIC versions (incl. RTL8116AF) can be properly
supported. This would have to include making the SFP I2C bus accessible by
the kernel (instead of firmware only).

RTL8116af is a multi-function device. fun0 is a BMC virtual driver and fun1 is
the nic driver. The BMC virtual driver(fun0) is used for power management,
while fun1 provides the actual network functionality.

Thanks,
