+See the DPDK Getting Started Guides for more information on these options.

+*   ``-c <COREMASK>`` or ``-l <CORELIST>``
+
+	Set the hexadecimal bitmask of the cores to run on. The corelist is a

+
+	One lcore is needed for process admin, tests are run on all other cores.
+	To run tests on two lcores, three lcores must be passed to the tool.

+*   ``-w <PCI>``
+
+	Add a PCI device in white list.
+
+*   ``--vdev <driver><id>``

+	Add a virtual device.
