+ * RTE_FLOW_ACTION_TYPE_SECURITY

+ * Perform the security action on flows matched by the pattern items
+ * according to the configuration of the security session.
+ *
+ * This action modifies the payload of matched flows. For INLINE_CRYPTO, the
+ * security protocol headers and IV are fully provided by the application as
+ * specified in the flow pattern. The payload of matching packets is
+ * encrypted on egress, and decrypted and authenticated on ingress.
+ * For INLINE_PROTOCOL, the security protocol is fully offloaded to HW,
+ * providing full encapsulation and decapsulation of packets in security
+ * protocols. The flow pattern specifies both the outer security header fields
+ * and the inner packet fields. The security session specified in the action
+ * must match the pattern parameters.
+ *
+ * The security session specified in the action must be created on the same
+ * port as the flow action that is being specified.
+ *
+ * The ingress/egress flow attribute should match that specified in the
+ * security session if the security session supports the definition of the
+ * direction.
+ *
+ * Multiple flows can be configured to use the same security session.
+ *
+ * Non-terminating by default.
