I am not sure. Running qemu with '-M realview-pbx-a9 -net model=help'
does not show the SMCS LAN9118 device.

I do not know what is happening here. There could be patches missing to
enabled SMC support for the realview machine in qemu.

I am playing with the Zynq at the moment. It at least runs but I am
having issues getting my network to talk to it.
