Hi Abdul,
Other's feel free to shoot me down.
But I am not sure that HelloWorld is really the example we want to show here.
HelloWorld is good and it minimizes the associated config you need to describe.
However does it really help a someone get started running DPDK in a container,
as there is no network interface.
Is there anyway we could show something running on a network interface?
Perhaps we contrive something simple with vEth, AF_Packet and TestPMD?
