Merge branch 'pktgen-scripts' 

Jesper Dangaard Brouer says:

====================
pktgen samples: new scripts and removing older samples

This patchset is adding some pktgen sample scripts that I've been
using for a while[1], and they seams to relevant for more people.

Patchset also remove some of the older style pktgen samples.
