Valid Indication
A 2-bit valid indication field indicates to the device that there is a
valid NVM present. If the valid field does not equal 10b the MAC
does not read the rest of the NVM data and default values are used
for the device configuration.
Reserved, set to 1b.
Reserved, set to 001b.
Enable PHY Power Down
When set, enables PHY power down at DMoff/D3 or Dr and no
WoL. This bit is loaded to the PHY Power Down Enable bit in the
Extended Device Control (CTRL_EXT) register.
1b = Enable PHY power down.
0b = PHY always powered up.
Reserved, should be set to 1b.
The value in this field is reflected in the PCI Power Management
Data register for D0 power consumption and dissipation
( Data_Select = 0 or 4). Power is defined in 100 mW units. The
power also includes the external logic required for the LAN
function.
Reserved, set to 000b.
The value in this field is reflected in the PCI Power Management
Data register for D3 power consumption and dissipation
( Data_Select = 3 or 7). Power is defined in 100 mW units. The
power also includes the external logic required for the LAN
function. The most significant bits in the Data register that reflects
the power values are padded with zeros.
