+Runtime Options
+~~~~~~~~~~~~~~~
+
+The following ``devargs`` options can be enabled at runtime. They must
+be passed as part of EAL arguments. For example,
+
+.. code-block:: console
+
+   testpmd -w 02:00.4,keep_ovlan=1 -- -i
+
+- ``keep_ovlan`` (default **0**)
+
+  Toggle behaviour to keep/strip outer VLAN in Q-in-Q packets. If
+  enabled, the outer VLAN tag is preserved in Q-in-Q packets. Otherwise,
+  the outer VLAN tag is stripped in Q-in-Q packets.
+
+- ``force_link_up`` (default **0**)
+
+  When set to 1, CXGBEVF PMD always forces link as up for all VFs on
+  underlying Chelsio NICs. This enables multiple VFs on the same NIC
+  to send traffic to each other even when the physical link is down.
