+ * @file
+ *
+ * RTE Ethernet Device API
+ *
+ * The Ethernet Device API is composed of two parts:
+ *
+ * - The application-oriented Ethernet API that includes functions to setup
+ *   an Ethernet device (configure it, setup its RX and TX queues and start it),
+ *   to get its MAC address, the speed and the status of its physical link,
+ *   to receive and to transmit packets, and so on.
+ *
+ * - The driver-oriented Ethernet API that exports a function allowing
+ *   an Ethernet Poll Mode Driver (PMD) to simultaneously register itself as
+ *   an Ethernet device driver and as a PCI driver for a set of matching PCI
+ *   [Ethernet] devices classes.
+ *
+ * By default, all the functions of the Ethernet Device API exported by a PMD
+ * are lock-free functions which assume to not be invoked in parallel on
+ * different logical cores to work on the same target object.  For instance,
+ * the receive function of a PMD cannot be invoked in parallel on two logical
+ * cores to poll the same RX queue [of the same port]. Of course, this function
+ * can be invoked in parallel by different logical cores on different RX queues.
+ * It is the responsibility of the upper level application to enforce this rule.
+ *
+ * If needed, parallel accesses by multiple logical cores to shared queues
+ * shall be explicitly protected by dedicated inline lock-aware functions
+ * built on top of their corresponding lock-free functions of the PMD API.
+ *
+ * In all functions of the Ethernet API, the Ethernet device is
+ * designated by an integer >= 0 named the device port identifier.
+ *
+ * At the Ethernet driver level, Ethernet devices are represented by a generic
+ * data structure of type *rte_eth_dev*.
+ *
+ * Ethernet devices are dynamically registered during the PCI probing phase
+ * performed at EAL initialization time.
+ * When an Ethernet device is being probed, an *rte_eth_dev* structure and
+ * a new port identifier are allocated for that device. Then, the eth_dev_init()
+ * function supplied by the Ethernet driver matching the probed PCI
+ * device is invoked to properly initialize the device.
+ *
+ * The role of the device init function consists of resetting the hardware,
+ * checking access to Non-volatile Memory (NVM), reading the MAC address
+ * from NVM etc.
+ *
+ * If the device init operation is successful, the correspondence between
+ * the port identifier assigned to the new device and its associated
+ * *rte_eth_dev* structure is effectively registered.
+ * Otherwise, both the *rte_eth_dev* structure and the port identifier are
+ * freed.
+ *
+ * The functions exported by the application Ethernet API to setup a device
+ * designated by its port identifier must be invoked in the following order:
+ *     - rte_eth_dev_configure()
+ *     - rte_eth_tx_queue_setup()
+ *     - rte_eth_rx_queue_setup()
+ *     - rte_eth_dev_start()
+ *
+ * Then, the network application can invoke, in any order, the functions
+ * exported by the Ethernet API to get the MAC address of a given device, to
+ * get the speed and the status of a device physical link, to receive/transmit
+ * [burst of] packets, and so on.
+ *
+ * If the application wants to change the configuration (i.e. call
+ * rte_eth_dev_configure(), rte_eth_tx_queue_setup(), or
+ * rte_eth_rx_queue_setup()), it must call rte_eth_dev_stop() first to stop the
+ * device and then do the reconfiguration before calling rte_eth_dev_start()
+ * again. The tramsit and receive functions should not be invoked when the
+ * device is stopped.
+ *
+ * Please note that some configuration is not stored between calls to
+ * rte_eth_dev_stop()/rte_eth_dev_start(). The following configuration will
+ * be retained:
+ *
+ *     - flow control settings
+ *     - receive mode configuration (promiscuous mode, hardware checksum mode,
+ *       RSS/VMDQ settings etc.)
+ *     - VLAN filtering configuration
+ *     - MAC addresses supplied to MAC address array
+ *     - flow director filtering mode (but not filtering rules)
+ *     - NIC queue statistics mappings
+ *
+ * Any other configuration will not be stored and will need to be re-entered
+ * after a call to rte_eth_dev_start().
+ *
+ * Finally, a network application can close an Ethernet device by invoking the
+ * rte_eth_dev_close() function.
+ *
+ * Each function of the application Ethernet API invokes a specific function
+ * of the PMD that controls the target device designated by its port
+ * identifier.
+ * For this purpose, all device-specific functions of an Ethernet driver are
+ * supplied through a set of pointers contained in a generic structure of type
+ * *eth_dev_ops*.
+ * The address of the *eth_dev_ops* structure is stored in the *rte_eth_dev*
+ * structure by the device init function of the Ethernet driver, which is
+ * invoked during the PCI probing phase, as explained earlier.
+ *
+ * In other words, each function of the Ethernet API simply retrieves the
+ * *rte_eth_dev* structure associated with the device port identifier and
+ * performs an indirect invocation of the corresponding driver function
+ * supplied in the *eth_dev_ops* structure of the *rte_eth_dev* structure.
+ *
+ * For performance reasons, the address of the burst-oriented RX and TX
+ * functions of the Ethernet driver are not contained in the *eth_dev_ops*
+ * structure. Instead, they are directly stored at the beginning of the
+ * *rte_eth_dev* structure to avoid an extra indirect memory access during
+ * their invocation.
+ *
+ * RTE ethernet device drivers do not use interrupts for transmitting or
+ * receiving. Instead, Ethernet drivers export Poll-Mode receive and transmit
+ * functions to applications.
+ * Both receive and transmit functions are packet-burst oriented to minimize
+ * their cost per packet through the following optimizations:
+ *
+ * - Sharing among multiple packets the incompressible cost of the
+ *   invocation of receive/transmit functions.
+ *
+ * - Enabling receive/transmit functions to take advantage of burst-oriented
+ *   hardware features (L1 cache, prefetch instructions, NIC head/tail
+ *   registers) to minimize the number of CPU cycles per packet, for instance,
+ *   by avoiding useless read memory accesses to ring descriptors, or by
+ *   systematically using arrays of pointers that exactly fit L1 cache line
+ *   boundaries and sizes.
+ *
+ * The burst-oriented receive function does not provide any error notification,
+ * to avoid the corresponding overhead. As a hint, the upper-level application
+ * might check the status of the device link once being systematically returned
+ * a 0 value by the receive function of the driver for a given number of tries.

+ * Retrieve a burst of input packets from a receive queue of an Ethernet
+ * device. The retrieved packets are stored in *rte_mbuf* structures whose

+ *
+ * The rte_eth_rx_burst() function loops, parsing the RX ring of the
+ * receive queue, up to *nb_pkts* packets, and for each completed RX
+ * descriptor in the ring, it performs the following operations:
+ *
+ * - Initialize the *rte_mbuf* data structure associated with the
+ *   RX descriptor according to the information provided by the NIC into
+ *   that RX descriptor.
+ *
+ * - Store the *rte_mbuf* data structure into the next entry of the
+ *   *rx_pkts* array.
+ *
+ * - Replenish the RX descriptor with a new *rte_mbuf* buffer
+ *   allocated from the memory pool associated with the receive queue at
+ *   initialization time.
+ *
+ * When retrieving an input packet that was scattered by the controller
+ * into multiple receive descriptors, the rte_eth_rx_burst() function
+ * appends the associated *rte_mbuf* buffers to the first buffer of the
+ * packet.
+ *
+ * The rte_eth_rx_burst() function returns the number of packets
+ * actually retrieved, which is the number of *rte_mbuf* data structures
+ * effectively supplied into the *rx_pkts* array.
+ * A return value equal to *nb_pkts* indicates that the RX queue contained
+ * at least *rx_pkts* packets, and this is likely to signify that other
+ * received packets remain in the input queue. Applications implementing
+ * a "retrieve as much received packets as possible" policy can check this
+ * specific case and keep invoking the rte_eth_rx_burst() function until
+ * a value less than *nb_pkts* is returned.
+ *
+ * This receive method has the following advantages:
+ *
+ * - It allows a run-to-completion network stack engine to retrieve and
+ *   to immediately process received packets in a fast burst-oriented
+ *   approach, avoiding the overhead of unnecessary intermediate packet
+ *   queue/dequeue operations.
+ *
+ * - Conversely, it also allows an asynchronous-oriented processing
+ *   method to retrieve bursts of received packets and to immediately
+ *   queue them for further parallel processing by another logical core,
+ *   for instance. However, instead of having received packets being
+ *   individually queued by the driver, this approach allows the invoker
+ *   of the rte_eth_rx_burst() function to queue a burst of retrieved
+ *   packets at a time and therefore dramatically reduce the cost of
+ *   enqueue/dequeue operations per packet.
+ *
+ * - It allows the rte_eth_rx_burst() function of the driver to take
+ *   advantage of burst-oriented hardware features (CPU cache,
+ *   prefetch instructions, and so on) to minimize the number of CPU
+ *   cycles per packet.
+ *
+ * To summarize, the proposed receive API enables many
+ * burst-oriented optimizations in both synchronous and asynchronous
+ * packet processing environments with no overhead in both cases.
+ *
+ * The rte_eth_rx_burst() function does not provide any error
+ * notification to avoid the corresponding overhead. As a hint, the

+ * being systematically returned a 0 value for a given number of tries.

+ * Send a burst of output packets on a transmit queue of an Ethernet device.
+ *
+ * The rte_eth_tx_burst() function is invoked to transmit output packets
+ * on the output queue *queue_id* of the Ethernet device designated by its
+ * *port_id*.
+ * The *nb_pkts* parameter is the number of packets to send which are
+ * supplied in the *tx_pkts* array of *rte_mbuf* structures.
+ * The rte_eth_tx_burst() function loops, sending *nb_pkts* packets,
+ * up to the number of transmit descriptors available in the TX ring of the
+ * transmit queue.
+ * For each packet to send, the rte_eth_tx_burst() function performs
+ * the following operations:
+ *
+ * - Pick up the next available descriptor in the transmit ring.
+ *
+ * - Free the network buffer previously sent with that descriptor, if any.
+ *
+ * - Initialize the transmit descriptor with the information provided
+ *   in the *rte_mbuf data structure.
+ *
+ * In the case of a segmented packet composed of a list of *rte_mbuf* buffers,
+ * the rte_eth_tx_burst() function uses several transmit descriptors
+ * of the ring.
+ *
+ * The rte_eth_tx_burst() function returns the number of packets it
+ * actually sent. A return value equal to *nb_pkts* means that all packets
+ * have been sent, and this is likely to signify that other output packets
+ * could be immediately transmitted again. Applications that implement a
+ * "send as many packets to transmit as possible" policy can check this
+ * specific case and keep invoking the rte_eth_tx_burst() function until
+ * a value less than *nb_pkts* is returned.
+ *
+ * It is the responsibility of the rte_eth_tx_burst() function to
+ * transparently free the memory buffers of packets previously sent.
+ * This feature is driven by the *tx_free_thresh* value supplied to the
+ * rte_eth_dev_configure() function at device configuration time.
+ * When the number of free TX descriptors drops below this threshold, the
+ * rte_eth_tx_burst() function must [attempt to] free the *rte_mbuf*  buffers
+ * of those packets whose transmission was effectively completed.
+ *
+ * @param port_id
+ *   The port identifier of the Ethernet device.
+ * @param queue_id
+ *   The index of the transmit queue through which output packets must be
+ *   sent.
+ *   The value must be in the range [0, nb_tx_queue - 1] previously supplied
+ *   to rte_eth_dev_configure().
+ * @param tx_pkts
+ *   The address of an array of *nb_pkts* pointers to *rte_mbuf* structures
+ *   which contain the output packets.
+ * @param nb_pkts
+ *   The maximum number of packets to transmit.
+ * @return
+ *   The number of output packets actually stored in transmit descriptors of
+ *   the transmit ring. The return value can be less than the value of the
+ *   *tx_pkts* parameter when the transmit ring is full or has been filled up.
