The value in this field is reflected in the PCI Power Management Data
register of the function 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
The value in this field is reflected in the PCI Power Management Data
Register of the function 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 function. The most significant
bits in the Data register that reflects the power values are padded with
zeros.
1b = Disables the LAN Flash BAR.
LAN boot expansion window size = 2 KB * 2 ** LANSIZE.
LAN Flash Address
Defines the location of the LAN boot expansion ROM in the physical Flash
device as defined in the following equation:
Word Address = 4 KB * (LBADD + PEND).
1b = Disables the LAN expansion boot ROM BAR.
Reserved, must be set to 0b.
Reserved, must be set to 0b.
Checksum Validity Indication
0b = Checksum should be corrected by software tools.
1b = Checksum may be considered valid.
Enable/disable bit for Deep Smart Power Down functionality.
0b = Enable Deep Smart Power Down (DSPD).
1b = Disable DSPD (default).
Reserved
This word must be set to 0xFF.
