PCIe Programming Interface—Ethernet Controller I210
621
Serial number definition in the I210:
Serial number uses the MAC address according to the following definition:
The serial number can be constructed from the 48-bit MAC address in the following form:
The MAC label in this case 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 MAC address as loaded from the Flash into the RAL and RAH registers.
The translation from Flash words 0 to 2 to the serial number is as follows:
• Serial number ADDR+0 = Flash byte 5
• Serial number ADDR+1 = Flash byte 4
• Serial number ADDR+2 = Flash byte 3
• Serial number ADDR+3 and 4 = 0xFF 0xFF
• Serial number ADDR+5 = Flash byte 2
• Serial number ADDR+6 = Flash byte 1
