+ * RTE SFT API
+ *
+ * Defines RTE SFT APIs for Statefull Flow Table library.
+ *
+ * SFT General description:
+ * SFT library provides a framework for applications that need to maintain
+ * context across different packets of the connection.
+ * Examples for such applications:
+ * - Next-generation firewalls
+ * - Intrusion detection/prevention systems (IDS/IPS): Suricata, Snort
+ * - SW/Virtual Switching: OVS
+ * The goals of the SFT library:
+ * - Accelerate flow recognition & its context retrieval for further lookaside
+ *   processing.
+ * - Enable context-aware flow handling offload.
+ *
+ * Definitions and Abbreviations:
+ * - 5-tuple: defined by:
+ *     -- Source IP address
+ *     -- Source port
+ *     -- Destination IP address
+ *     -- Destination port
+ *     -- IP protocol number
+ * - 7-tuple: 5-tuple zone and port (see struct rte_sft_7tuple)
+ * - 5/7-tuple: 5/7-tuple of the packet from connection initiator
+ * - revers 5/7-tuple: 5/7-tuple of the packet from connection initiate
+ * - application: SFT library API consumer
+ * - APP: see application
+ * - CID: client ID
+ * - CT: connection tracking
+ * - FID: Flow identifier
+ * - FIF: First In Flow
+ * - Flow: defined by 7-tuple and its reverse i.e. flow is bidirectional
+ * - SFT: Stateful Flow Table
+ * - user: see application
+ * - zone: additional user defined value used as differentiator for
+ *         connections having same 5-tuple (for example different VxLan
+ *         connections with same inner 5-tuple).

+ * SFT as datastructure:
+ * SFT can be treated as datastructure maintaining flow context across its
+ * lifetime. SFT flow entry represent bidirectional network flow and defined by
+ * 7-tuple & its reverse 7-tuple.
+ * Each entry in SFT has:
+ * - FID: 1:1 mapped & used as entry handle & encapsulating internal
+ *   implementation of the entry.
+ * - State: user-defined value attached to each entry, the only library
+ *   reserved value for state unset (the actual value defined by SFT
+ *   configuration). The application should define flow state encodings and
+ *   set it for flow via rte_sft_flow_set_ctx() than what actions should be
+ *   applied on packets can be defined via related RTE flow rule matching SFT
+ *   state (see rules in SFT components diagram above).
+ * - Timestamp: for the last seen in flow packet used for flow aging mechanism
+ *   implementation.
+ * - Client Objects: user-defined flow contexts attached as opaques to flow.
+ * - Acceleration & offloading - utilize RTE flow capabilities, when supported
+ *   (see action ``SFT``), for flow lookup acceleration and further
+ *   context-aware flow handling offload.
+ * - CT state: optionally for TCP connections CT state can be maintained
+ *   (see enum rte_sft_flow_ct_state).
+ * - Out of order TCP packets: optionally SFT can keep out of order TCP
+ *   packets aside the flow context till the arrival of the missing in-order
+ *   packet.
+ *
+ * RTE flow changes:
+ * The SFT flow state (or context) for RTE flow is defined by fields of
+ * struct rte_flow_item_sft.
+ * To utilize SFT capabilities new item and action types introduced:
+ * - item SFT: matching on SFT flow state (see RTE_FLOW_ITEM_TYPE_SFT).
+ * - action SFT: retrieve SFT flow context and attache it to the processed
+ *   packet (see RTE_FLOW_ACTION_TYPE_SFT).
+ *
+ * The contents of per port SFT serving RTE flow action ``SFT`` managed via
+ * SFT PMD APIs (see struct rte_sft_ops).
+ * The SFT flow state/context retrieval performed by user-defined zone ``SFT``
+ * action argument and processed packet 5-tuple.
+ * If in scope of action ``SFT`` there is no context/state for the flow in SFT
+ * undefined sate attached to the packet meaning that the flow is not
+ * recognized by SFT, most probably FIF packet.
+ *
+ * Once the SFT state set for a packet it can match on item SFT
+ * (see RTE_FLOW_ITEM_TYPE_SFT) and forwarding design can be done for the
+ * packet, for example:
+ * - if state value == x than queue for further processing by the application
+ * - if state value == y than forward it to eth port (full offload)
+ * - if state value == 'undefined' than queue for further processing by
+ *   the application (handle FIF packets)
+ *
+ * Processing packets with SFT library:
+ *
+ * FIF packet:
+ * To recognize upcoming packets of the SFT flow every FIF packet should be
+ * forwarded to the application utilizing the SFT library. Non-FIF packets can
+ * be processed by the application or its processing can be fully offloaded.
+ * Processing of the packets in SFT library starts with rte_sft_process_mbuf
+ * or rte_sft_process_mbuf_with_zone. If mbuf recognized as FIF application
+ * should make a design to destroy flow or complete flow creation process in
+ * SFT using rte_sft_flow_activate.
+ *
+ * Recognized SFT flow:
+ * Once struct rte_sft_flow_status with valid fid field posesed by application
+ * it can:
+ * - mange client objects on it (see client_obj field in
+ *   struct rte_sft_flow_status) using rte_sft_flow_<OP>_client_obj APIs
+ * - analyze user-defined flow state and CT state (see state & ct_sate fields
+ *   in struct rte_sft_flow_status).
+ * - set flow state to be attached to the upcoming packets by action ``SFT``
+ *   via struct rte_sft_flow_status API.
+ * - decide to destroy flow via rte_sft_flow_destroy API.
+ *
+ * Flow aging:
+ *
+ * SFT library manages the aging for each flow. On flow creation, it's
+ * assigned an aging value, the maximal number of seconds passed since the
+ * last flow packet arrived, once exceeded flow considered aged.
+ * The application notified of aged flow asynchronously via event queues.
+ * The device and port IDs tuple to identify the event queue to enqueue
+ * flow aged events passed on flow creation as arguments
+ * (see rte_sft_flow_activate). It's the application responsibility to
+ * initialize event queues and assign them to each flow for EOF event
+ * notifications.
+ * Aged EOF event handling:
+ * - Should be considered as application responsibility.
+ * - The last stage should be the release of the flow resources via
+ *    rte_sft_flow_destroy API.
+ * - All client objects should be removed from flow before the
+ *   rte_sft_flow_destroy API call.
+ * See the description of rete_sft_flow_destroy for an example of aged flow
+ * handling.
+ *
+ * SFT API thread safety:
+ *
+ * SFT library APIs are thread-safe while handling of specific flow can be
+ * done in a single thread simultaneously. Exclusive access to specific SFT
+ * flow guaranteed by:
+ * - rte_sft_process_mbuf
+ * - rte_sft_process_mbuf_with_zone
+ * - rte_sft_flow_create
+ * - rte_sft_flow_lock
+ * When application is done with the flow handling for the current packet it
+ * should call rte_sft_flow_unlock API to maintain exclusive access to the
+ * flow with other threads.
+ *
+ * SFT Library initialization and cleanup:
+ *
+ * SFT library should be considered as a single instance, preconfigured and
+ * initialized via rte_sft_init() API.
+ * SFT library resource deallocation and cleanup should be done via
+ * rte_sft_init() API as a stage of the application termination procedure.
