Actions
~~~~~~~
This action modifies the payload of matched flows.
+Action: ``RAW_ENCAP``
+^^^^^^^^^^^^^^^^^^^^^
+
+Adds outer header whose template is provided in its data buffer,
+as defined in the ``rte_flow_action_raw_encap`` definition.
+
+This action modifies the payload of matched flows. The data supplied must
+be a valid header, either holding layer 2 data in case of adding layer 2 after
+decap layer 3 tunnel (for example MPLSoGRE) or complete tunnel definition
+starting from layer 2 and moving to the tunnel item itself. When applied to
+the original packet the resulting packet must be a valid packet.

+Action: ``RAW_DECAP``
+^^^^^^^^^^^^^^^^^^^^^^^

+be a valid header, either holding layer 2 data in case of removing layer 2
+before eincapsulation of layer 3 tunnel (for example MPLSoGRE) or complete
+tunnel definition starting from layer 2 and moving to the tunnel item itself.
