 This is a complete, working driver for the `PCI\VEN_10EC&DEV_8168&SUBSYS_816810EC&REV_03` device.
 The device is based on the PCI bus, uses bus-mastering DMA to transfer data, and uses line-based interrupts.
 The hardware supports checksum offload, interupt moderation, and several Wake-on-LAN patterns.
