[PATCH v9 2/7] dts: limit EAL parameters to DPDK apps and add parameters to all apps

[jspewock@iol.unh.edu]

From: Jeremy Spewock <jspewock@iol.unh.edu>

Changed the factory method for creating interactive apps in the SUT Node
so that EAL parameters would only be passed into DPDK apps since
non-DPDK apps wouldn't be able to process them. Also modified
interactive apps to allow for the ability to pass parameters into the
app on startup so that the applications can be started with certain
configuration steps passed on the command line.
