The\n+ * service function deqeueues events from its event port and transmits the\n+ * mbufs referenced by these events.\n+ *\n+ * The ethernet Tx event adapter APIs are:\n+ *\n+ * - rte_event_eth_tx_adapter_create()\n+ * - rte_event_eth_tx_adapter_create_ext()\n+ * - rte_event_eth_tx_adapter_free()\n+ * - rte_event_eth_tx_adapter_start()\n+ * - rte_event_eth_tx_adapter_stop()\n+ * - rte_event_eth_tx_adapter_queue_start()\n+ * - rte_event_eth_tx_adapter_queue_stop()\n+ * - rte_event_eth_tx_adapter_enqueue()\n+ * - rte_event_eth_tx_adapter_stats_get()\n+ * - rte_event_eth_tx_adapter_stats_reset()\n+ *\n+ * The application creates the adapter using\n+ * rte_event_eth_tx_adapter_create(). The adapter may internally create an event\n+ * port using the port configuration parameter.\n+ * The adapter is responsible for linking the queue as per its implementation,\n+ * for example in the case of the service function, the adapter links this queue\n+ * to the event port it will dequeue events from.\n+ *\n+ * The application uses rte_event_eth_tx_adapter_enqueue() to send mbufs to the\n+ * adaptervia this event queue. The ethernet port and transmit queue index to\n+ * transmit the mbuf on are specified in the mbuf.\n+ *\n+ * The application can start and stop the adapter using the\n+ * rte_event_eth_tx_adapter_start/stop() calls.\n+ *\n+ * To support dynamic reconfiguration of Tx queues, the application can\n+ * call rte_event_eth_tx_adapter_queue_start()/stop() to synchronize\n+ * access to the Tx queue with the adapter. For example, if the application\n+ * wants to reconfigure a Tx queue that could be concurrently\n+ * being accessed by the adapter, it calls rte_event_eth_tx_adapter_queue_stop()\n+ * first, reconfigures the queue and then calls\n+ * rte_event_eth_tx_adapter_queue_start() which signals to the adapter\n+ * that it is safe to resume access to the Tx queue.\n+ *\n+ * The common adapter implementation uses an EAL service function as described\n+ * before and its execution is controlled using the rte_service APIs. The\n+ * rte_event_eth_tx_adapter_service_id_get()\n+ * function can be used to retrieve the adapter's service function ID.\n+ */\n+\n+#ifdef __cplusplus\n+extern \"C\" {\n+#endif\n+\n+#include <stdint.h>\n+\n+#include \"rte_eventdev.h\"\n+\n+#define RTE_EVENT_ETH_TX_ADAPTER_MAX_INSTANCE 32\n+\n+/**\n+ * @warning\n+ * @b EXPERIMENTAL: this API may change without prior notice\n+ *\n+ * Adapter configuration structure\n+ */\n+struct rte_event_eth_tx_adapter_conf {\n+\tuint8_t event_port_id;\n+\t/**< Event port identifier, the adapter service function dequeues mbuf\n+\t * events from this port.\n+\t */\n+\tuint32_t max_nb_tx;\n+\t/**< The adapter can return early if it has processed at least\n+\t * max_nb_tx mbufs.
