+Event Ethernet Tx Adapter Library
+=================================
+
+The DPDK Eventdev API allows the application to use an event driven programming
+model for packet processing in which the event device distributes events
+referencing packets to the application cores in a dynamic load balanced fashion
+while handling atomicity and packet ordering. Event adapters provide the interface
+between the ethernet, crypto and timer devices and the event device. Event adapter
+APIs enable common application code by abstracting PMD specific capabilities.
+The Event ethernet Tx adapter provides configuration and data path APIs for the
+transmit stage of the application allowing the same application code to use eventdev
+PMD support or in its absence, a common implementation.
+
+In the common implementation, the application enqueues mbufs to the adapter
+which runs as a rte_service function. The service function dequeues events
+from its event port and transmits the mbufs referenced by these events.
+
+
+API Walk-through
+----------------
+
+This section will introduce the reader to the adapter API. The
+application has to first instantiate an adapter which is associated with
+a single eventdev, next the adapter instance is configured with Tx queues,
+finally the adapter is started and the application can start enqueuing mbufs
+to it.
+
+Creating an Adapter Instance
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+An adapter instance is created using ``rte_event_eth_tx_adapter_create()``. This
+function is passed the event device to be associated with the adapter and port
+configuration for the adapter to setup an event port if the adapter needs to use
+a service function.
+
+If the application desires to have finer control of eventdev port configuration,
+it can use the ``rte_event_eth_tx_adapter_create_ext()`` function. The
+``rte_event_eth_tx_adapter_create_ext()`` function is passed a callback function.
+The callback function is invoked if the adapter needs to use a service function
+and needs to create an event port for it. The callback is expected to fill the
+``struct rte_event_eth_tx_adapter_conf`` structure passed to it.
+
+.. code-block:: c
+
+        struct rte_event_dev_info dev_info;
+        struct rte_event_port_conf tx_p_conf = {0};
+
+        err = rte_event_dev_info_get(id, &dev_info);
+
+        tx_p_conf.new_event_threshold = dev_info.max_num_events;
+        tx_p_conf.dequeue_depth = dev_info.max_event_port_dequeue_depth;
+        tx_p_conf.enqueue_depth = dev_info.max_event_port_enqueue_depth;
+
+        err = rte_event_eth_tx_adapter_create(id, dev_id, &tx_p_conf);
+
+Adding Tx Queues to the Adapter Instance
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Ethdev Tx queues are added to the instance using the
+``rte_event_eth_tx_adapter_queue_add()`` function. A queue value
+of -1 is used to indicate all queues within a device.
+
+.. code-block:: c
+
+        int err = rte_event_eth_tx_adapter_queue_add(id,
+						     eth_dev_id,
+						     q);
+
+Querying Adapter Capabilities
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``rte_event_eth_tx_adapter_caps_get()`` function allows
+the application to query the adapter capabilities for an eventdev and ethdev
+combination. Currently, the only capability flag defined is
+``RTE_EVENT_ETH_TX_ADAPTER_CAP_INTERNAL_PORT``, the application can
+query this flag to determine if a service function is associated with the
+adapter and retrieve its service identifier using the
+``rte_event_eth_tx_adapter_service_id_get()`` API.
+
+
+.. code-block:: c
+
+        int err = rte_event_eth_tx_adapter_caps_get(dev_id, eth_dev_id, &cap);
+
+        if (!(cap & RTE_EVENT_ETH_TX_ADAPTER_CAP_INTERNAL_PORT))
+                err = rte_event_eth_tx_adapter_service_id_get(id, &service_id);
+
+Linking a Queue to the Adapter's Event Port
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the adapter uses a service function as described in the previous section, the
+application is required to link a queue to the adapter's event port. The adapter's
+event port can be obtained using the ``rte_event_eth_tx_adapter_event_port_get()``
+function. The queue can be configured with the ``RTE_EVENT_QUEUE_CFG_SINGLE_LINK``
+since it is linked to a single event port.
+
+Configuring the Service Function
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the adapter uses a service function, the application can assign
+a service core to the service function as shown below.
+
+.. code-block:: c
+
+        if (rte_event_eth_tx_adapter_service_id_get(id, &service_id) == 0)
+                rte_service_map_lcore_set(service_id, TX_CORE_ID);
+
+Starting the Adapter Instance
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The application calls ``rte_event_eth_tx_adapter_start()`` to start the adapter.
+This function calls the start callback of the eventdev PMD if supported,
+and the ``rte_service_run_state_set()`` to enable the service function if one exists.
+
+Enqueuing Packets to the Adapter
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The application needs to notify the adapter about the transmit port and queue used
+to send the packet. The transmit port is set in the ``struct rte mbuf::port`` field
+and the transmit queue is set using the ``rte_event_eth_tx_adapter_txq_set()``
+function.
+
+If the eventdev PMD supports the ``RTE_EVENT_ETH_TX_ADAPTER_CAP_INTERNAL_PORT``
+capability for a given ethernet device, the application should use the
+``rte_event_eth_tx_adapter_enqueue()`` function to enqueue packets to the adapter.
+
+If the adapter uses a service function for the ethernet device then the application
+should use the ``rte_event_enqueue_burst()`` function.
+
+.. code-block:: c
+
+	struct rte_event event;
+
+	if (cap & RTE_EVENT_ETH_TX_ADAPTER_CAP_INTERNAL_PORT) {
+
+		event.mbuf = m;
+
+		m->port = tx_port;
+		rte_event_eth_tx_adapter_txq_set(m, tx_queue_id);
+
+		rte_event_eth_tx_adapter_enqueue(dev_id, ev_port, &event, 1);
+	} else {
+
+		event.queue_id = qid; /* event queue linked to adapter port */
+		event.op = RTE_EVENT_OP_NEW;
+		event.event_type = RTE_EVENT_TYPE_CPU;
+		event.sched_type = RTE_SCHED_TYPE_ATOMIC;
+		event.mbuf = m;
+
+		m->port = tx_port;
+		rte_event_eth_tx_adapter_txq_set(m, tx_queue_id);
+
+		rte_event_enqueue_burst(dev_id, ev_port, &event, 1);
+	}
+
+Getting Adapter Statistics
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The  ``rte_event_eth_tx_adapter_stats_get()`` function reports counters defined
+in struct ``rte_event_eth_tx_adapter_stats``. The counter values are the sum of
+the counts from the eventdev PMD callback if the callback is supported, and
+the counts maintained by the service function, if one exists.
