Reserved, set to 00b.
When set, enables loading of the extended LAN connected device
configuration area in the 82577. This configuration area also
includes the PHY tuning (tuning for IEEE) in the NVM. Since this bit
is set to 0b by default, PHY tuning does not take effect until the LAN
driver and/or firmware loads. When disabled, the extended LAN
connected device configuration area is ignored. Loaded to the
EXTCNF_CTRL register.
When set, enables auto load of the OEM bits from the PHY_CTRL
register to the PHY. OEM bits include any LED configuration. Since
this bit is set to 0b by default, the auto-load of OEM bits do not take
effect until the LAN driver and/or firmware loads. Loaded to the
Extended Configuration Control register (EXTCNF_CTRL[3]).
1b = OEM bits written to the 82577.
0b = No OEM bits configuration.
Defines the base address (in Dwords) of the Extended Configuration
area in the NVM. The base address defines an offset value relative
to the beginning of the LAN space in the NVM. A value of 0x00 is not
supported when operating with the 82577. Loaded to the Extended
Configuration Control register (EXTCNF_CTRL[27:16]).
Size (in Dwords) of the Extended PHY configuration area loaded to
the Extended Configuration Size register (EXTCNF_SIZE[23:16]). If
an extended configuration area is disabled by bit 13 in word 0x14,
its length must be set to zero.
Reserved, must be set to 0x00.
Reserved, set to 0x00.
Reserved, set to 0x00.
