Hardware Accessed Words
This section describes the NVM words that are loaded by the MAC 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) or LAN on Motherboard (LOM), 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 section, the IA byte numbering convention is indicated as
follows; byte 1, bit 0 is first on the wire and byte 6, bit 7 is last. Note that byte 1, bit 0
is the unicast/multicast address indication while zero means unicast address. Byte 1,
bit 1 identifies the global/local indication while zero means a global address.
