Status Register (Offset 0x6)
Shaded fields are not used by this implementation and are hardwired to 0b.
1. The Interrupt Status field is a read-only field that indicates that an interrupt message is
Revision ID (Offset 0x8)
The default revision ID of this device is 0x0. The value of the rev ID is a logic XOR
between the default value and the value in the NVM word 0x1E.
Class Code (Offset 0x9)
The class code is a read-only, hard-coded value that identifies the device functionality.
LAN - 0x020000 - Ethernet Adapter
Cache Line Size (Offset 0xC)
This field is implemented by PCIe devices as a read-write field for legacy compatibility
purposes but has no impact on any PCIe device functionality. Loaded from NVM words
0x1A.
Latency Timer (Offset 0xD)
Not used. Hardwired to 0b.
Header Type (Offset 0xE)
This indicates if a device is single function or multifunction. For the 82574 this field has
a value of 0x00 to indicate a single function device.

Interrupt Status
New Capabilities
Indicates that a device implements extended capabilities. The
82574 sets this bit, and implements a capabilities list, to
indicate that it supports PCI power management, message
signaled interrupts, and the PCIe extensions.
