Detailed Description

This device usually comes as a PCIe card with two functions, each acting as a separate NIC with a few exceptions.

There are several shared resources: EEPROM, PHY(s), Flash. If access to those resources is desired, the hardware-semaphore of the 82576 has to be used. We can blissfully ignore it, because we do not need access to any shared resource.
