The application uses the adapter APIs to configure\n+ * the packet flow between the ethernet devices and event devices. Depending on\n+ * on the capabilties of the eventdev PMD, the adapter may use a EAL service\n+ * core function for packet transfer or use internal PMD functions to configure\n+ * the packet transfer between the ethernet device and the event device.\n+ *\n+ * The ethernet Rx event adapter's functions are:\n+ *  - rte_event_eth_rx_adapter_create_ext()\n+ *  - rte_event_eth_rx_adapter_create()/free()\n+ *  - rte_event_eth_rx_adapter_queue_add()/del()\n+ *  - rte_event_eth_rx_adapter_start()/stop()\n+ *  - rte_event_eth_rx_adapter_stats_get()/reset()\n+ *\n+ * The applicaton creates an event to ethernet adapter using\n+ * rte_event_eth_rx_adapter_create_ext() or rte_event_eth_rx_adapter_create()\n+ * functions.\n+ * The adapter needs to know which ethernet rx queues to poll for mbufs as well\n+ * as event device parameters such as the event queue identifier, event\n+ * priority and scheduling type that the adapter should use when constructing\n+ * events. The rte_event_eth_rx_adapter_queue_add() function is provided for\n+ * this purpose.\n+ * The servicing weight parameter in the rte_event_eth_rx_adapter_queue_conf\n+ * is applicable when the Rx adapter uses a service core function and is\n+ * intended to provide application control of the polling frequency of ethernet\n+ * device receive queues, for example, the application may want to poll higher\n+ * priority queues with a higher frequency but at the same time not starve\n+ * lower priority queues completely. If this parameter is zero and the receive\n+ * interrupt is enabled when configuring the device, the receive queue is\n+ * interrupt driven; else, the queue is assigned a servicing weight of one.\n+ *\n+ * If the adapter uses a rte_service function, then the application is also\n+ * required to assign a core to the service function and control the service\n+ * core using the rte_service APIs. The rte_event_eth_rx_adapter_service_id_get\n+ * function can be used to retrieve the service function ID of the adapter in\n+ * this case.\n+ *\n+ * Note: Interrupt driven receive queues are currentely unimplemented.\n+ */\n+\n+#ifdef __cplusplus\n+extern \"C\" {\n+#endif\n+\n+#include <stdint.h>\n+#include <rte_service.h>\n+\n+#include \"rte_eventdev.h\"\n+\n+#define RTE_EVENT_ETH_RX_ADAPTER_NAME_FORMAT\t\"rte_event_eth_rx_adapter_%d\"\n+\n+#define RTE_MAX_EVENT_ETH_RX_ADAPTER_INSTANCE 32\n+\n+/* struct rte_event_eth_rx_adapter_queue_conf flags definitions */\n+#define RTE_EVENT_ETH_RX_ADAPTER_QUEUE_FLOW_ID_VALID\t0x1\n+/**< This flag indicates the flow identifier is valid\n+ * @see rte_event_eth_rx_adapter_queue_conf\n+ */\n+\n+struct rte_event_eth_rx_adapter_conf {\n+\tuint8_t event_port_id;\n+\t/**< Event port identifier, the adapter enqueues mbuf events to this\n+\t * port\n+\t */\n+\tuint32_t max_nb_rx;\n+\t/**< The adapter can return early if it has processed at least\n+\t * max_nb_rx mbufs.
