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. [1] https://github.com/netoptimizer/network-testing/tree/master/pktgen ==================== Signed-off-by: David S.
