Revision Identification Value — RO. This 8-bit value indicates the revision number for the
integrated LAN controller. The three least significant bits in this register may be overridden by the ID
and REV ID fields in the EEPROM.
Sub Class Code — RO . 8-bit value that specifies the sub-class of the device as an Ethernet
controller.
Base Class Code — RO . 8-bit value that specifies the base class of the device as a network
controller.
Reserved
Cache Line Size (CLS) — R/W.
00 = Memory Write and Invalidate (MWI) command will not be used by the integrated LAN controller.
01 = MWI command will be used with Cache Line Size set to 8 DWords (only set if a value of 08h is
10 = MWI command will be used with Cache Line Size set to 16 DWords (only set if a value of 10h is
11 = Invalid. MWI command will not be used.
