From 89157abb9dd030c7d1cb7bc20df843b236358a33 Mon Sep 17 00:00:00 2001
From: Ryan Harkin <ryan.harkin@linaro.org>
Date: Tue, 16 Feb 2016 10:26:46 +0000
Subject: Add networking params

If the users specifies NET=1 when launching the model, the networking
params will be appended to the model launch commandline.

When using the AEMv8 models, if the MAC address is not supplied, a MAC
address will be generated.
