Description
RO
PCIe Device Serial Number. This field contains the IEEE defined 64-bit 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.
The serial number uses the MAC address according to the following definition:
Field
Company ID
Order
Addr+0
Addr+1
Addr+2
Most Significant Byte
Most Significant Bit
Addr+3
Extension Identifier
Addr+4
Addr+5
Addr+6
Addr+7
Least Significant Byte
Least Significant Bit
The serial number can be constructed from the 48-bit MAC address in the following form:
Field
Company ID
Order
Addr+0
Addr+1
Addr+2
Most Significant Bytes
Most Significant Bit
MAC Label
Addr+3
Addr+4
Extension identifier
Addr+5

In this case, the MAC label 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:
Field
Company ID
Order
Addr+0

The MAC address is the function 0 MAC address that is loaded from EEPROM into the RAL and RAH
registers.
