The Pktgen command line looks find to me and I assume the lcores being used are full physical core?

Eg. -l 0-8 and -l 31-32,34 this also assumes the lcores are per physical core. If you run the tools/cpu_info.py script you will be able to see the lcore/core relationship. > > but the l2fwd does not.
