 The information from above is taken from two new files pktgen-master.sh
 and pktgen-slave.sh, have a look at them and adjust as you need.
+The following DPDK / EAL options must be configured correctly as well:
+* ``-l lcore_id_list``: non-conflicting list of lcores for each app
+* ``--master-lcore lcore_id``: non-conflicting master lcore for each app
+* ``-m hugepage_mb / --socket-mem hugepage_mb_list``: non-conflicting amount
+of hugepage memory for each app, or for each app on each CPU socket
+* ``--no-shconf``: prevents DPDK from claiming a lockfile that breaks
+concurrent use of multiple apps
+* ``--file-prefix``: assigns a unique name to the hugepage mmap() files for
+each app
 Pktgen can also be configured using the :ref:`commands`.
