This section describes the NVM words that are loaded by the 82574 hardware.
Ethernet Address (Words 0x00-0x02)
The Ethernet Individual Address (IA) is a 6-byte field that must be unique for each
Network Interface Card (NIC), and thus unique for each copy of the NVM image. The
first three bytes are vendor specific - for example, the IA is equal to [00 AA 00] or [00
A0 C9] for Intel products. The value from this field is loaded into the Receive Address
Register 0 (RAL0/RAH0).
For the purpose of this specification, the IA byte numbering convention is indicated
below:
