I fear that it is currently not possible to configure this network interface on l4linux for vexpress-a9. QEMU (v220.127.116.11) supports
lan9118 only but the l4linux smsc911x.c requires CONFIG_OF in smsc911x_probe_config_dt. But configuring via DT is not yet fully
working in l4re-snapshot-2014092821.
