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

BTW, it maybe easier to see which cores are being used here by using the -l <lcores-numbers> instead of -c. 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.
