CONFIG_5
Do not change this field without Realtek approval.
Bit7-3: Reserved.
Bit2: Link Down Power Saving mode:
Set to 1: Disable.
Set to 0: Enable. When cable is disconnected(Link Down), the analog part will power
down itself (PHY Tx part & part of twister) automatically except PHY Rx part and
part of twister to monitor SD signal in case that cable is re-connected and Link should
be established again.
Bit1: LANWake signal Enable/Disable
Set to 1: Enable LANWake signal.
Set to 0: Disable LANWake signal.
Bit0: PME_Status bit property
Set to 1: The PME_Status bit can be reset by PCI reset or by software if
D3cold_support_PME is 0. If D3cold_support_PME=1, the PME_Status bit is a
sticky bit.
Set to 0: The PME_Status bit is always a sticky bit and can only be reset by software.
