Whole Device is at deep PD
When both LAN ports are disabled following a Power on Reset / LAN_PWR_GOOD/ PE_RST_N/ In-Band
reset the LANx_DIS_N signals should be tied statically to low. At this state the device is disabled, LAN
ports are powered down, all internal clocks are shut and the PCIe connection is powered down (similar
to L2 state).
