10.1.5.2.2.2 Serial Number Register (Offset 0x04)
The Serial Number register is a 64-bit field that contains the IEEE defined 64-bit
extended unique identifier (EUI-64™). Figure 49 details the allocation of register fields
in the Serial Number register. The following table lists the respective bit definitions.

RO
PCIe Device Serial Number
This field contains the IEEE defined 64-bit extended unique identifier (EUI-64™).
This identifier includes a 24-bit company ID value assigned by IEEE registration
authority and a 40-bit extension identifier assigned by the manufacturer.
10.1.5.2.2.3 Serial Number Definition in The 82583V
The serial number can be constructed from the 48-bit MAC address in the following
form:

Serial Number Definition in The 82583V 48-Bit MAC Address
The MAC label in the 82583V is 0xFFFF.
For example, assume that the company ID is (Intel) 00-A0-C9 and the extension
identifier is 23-45-67. In this case, the 64-bit serial number is:
