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™).
in the Serial Number register. The following table lists the respective bit definitions.
Serial Number Register
Serial Number Definition in The 82574
The serial number can be constructed from the 48-bit MAC address in the following
form:
Serial Number Definition in The 82574 48-Bit MAC Address
The MAC label in the 82574 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:
The MAC address is the function 0 MAC address as loaded from NVM into the RAL and
RAH registers.
