OUI Least Significant Bits:
Bits 19 to 24 of the OUI (080017h) are mapped from bits 15 to 10 of this register
respectively.
Vendor Model Number:
The six bits of vendor model number are mapped from bits 9 to 4 (most significant bit
to bit 9).
Model Revision Number:
Four bits of the vendor model revision number are mapped from bits 3 to 0 (most
significant bit to bit 3). This field will be incremented for all major device changes.
OUI Most Significant Bits: Bits 3 to 18 of the OUI (080017h) are stored in bits 15
to 0 of this register. The most significant two bits of the OUI are ignored (the IEEE
standard refers to these as bits 1 and 2).
