This, most likely, implies that dde_ipxe did not come up for the rtl8169
card. The thing is, we cannot test this card over here, since we don't
own one. Is there a way you could provide the serial (UART) log output?
Console only is unfortunately not sufficient here. So, for now I would
leave 'nic_drv' commented.
