PCI-Compatible Configuration Registers
Explanation of the various registers in the 82574 is as follows.
Vendor ID (Offset 0x0)
This is a read-only register that has the same value for all PCI functions. It uniquely
identifies Intel products. The field default value is 0x8086.
Device ID (Offset 0x2)
This is a read-only register. The value is loaded from NVM. Default value is 0x10D3 for
the 82574.
Command Reg (Offset 0x4)
Read-write register. Layout is as follows. Shaded bits are not used by this
implementation and are hardwired to 0b.
