The RTL8211E-VB(VL)/RTL8211EG-VB has a PHYRSTB pin to reset the chip. For a complete PHY

reset, this pin must be asserted low for at least 10ms (Tgap in Figure 10) for the internal regulator. Wait for

a further 30ms (for internal circuits settling time) before accessing the PHY register. All registers will

return to default values after a hardware reset. Refer to the RTL8211xx-xx_Power_Sequence_App_Note

for more detailed information.
