+
+    Enable printing the occurrence of the designated event. Using all will

+    disable all of them.
+
+*   ``--flow-isolate-all``
+
+    Providing this parameter requests flow API isolated mode on all ports at
+    initialization time. It ensures all traffic is received through the

+*   ``--hot-plug``
+
+    Enable device event monitor machenism for hotplug.
+
+*   ``--vxlan-gpe-port=N``
+
+    Set the UDP port number of tunnel VXLAN-GPE to N.
+    The default value is 4790.
+
+*   ``--mlockall``
+
+    Enable locking all memory.
+
+*   ``--no-mlockall``
+
+    Disable locking all memory.
+
+*   ``--mp-alloc <native|anon|xmem|xmemhuge>``
+
+    Select mempool allocation mode:
+
+    * native: create and populate mempool using native DPDK memory
+    * anon: create mempool using native DPDK memory, but populate using
+      anonymous memory
+    * xmem: create and populate mempool using externally and anonymously
+      allocated area
+    * xmemhuge: create and populate mempool using externally and anonymously
+      allocated hugepage area
+
+*   ``--noisy-tx-sw-buffer-size``
+
+    Set the number of maximum elements  of the FIFO queue to be created
+    for buffering packets. Only available with the noisy forwarding mode.
