+Action: ``VXLAN_ENCAP``
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Performs a VXLAN encapsulation action by encapsulating the matched flow in the
+VXLAN tunnel as defined in the``rte_flow_action_vxlan_encap`` flow items
+definition.
+
+This action modifies the payload of matched flows. The flow definition specified
+in the ``rte_flow_action_tunnel_encap`` action structure must define a valid
+VLXAN network overlay which conforms with RFC 7348 (Virtual eXtensible Local
+Area Network (VXLAN): A Framework for Overlaying Virtualized Layer 2 Networks
+over Layer 3 Networks). The pattern must be terminated with the
+RTE_FLOW_ITEM_TYPE_END item type.

+Action: ``VXLAN_DECAP``
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Performs a decapsulation action by stripping all headers of the VXLAN tunnel
+network overlay from the matched flow.
+
+The flow items pattern defined for the flow rule with which a ``VXLAN_DECAP``
+action is specified, must define a valid VXLAN tunnel as per RFC7348. If the
+flow pattern does not specify a valid VXLAN tunnel then a
+RTE_FLOW_ERROR_TYPE_ACTION error should be returned.
+
+This action modifies the payload of matched flows.

+Performs a NVGRE encapsulation action by encapsulating the matched flow in the

+definition.
+
+This action modifies the payload of matched flows. The flow definition specified
+in the ``rte_flow_action_tunnel_encap`` action structure must defined a valid
+NVGRE network overlay which conforms with RFC 7637 (NVGRE: Network
+Virtualization Using Generic Routing Encapsulation). The pattern must be
+terminated with the RTE_FLOW_ITEM_TYPE_END item type.
