+ * . Writes to memory are not reordered with other writes,
+ *   with the following exceptions:
+ *   . streaming stores (writes) executed with the non-temporal move
+ *     instructions (MOVNTI, MOVNTQ, MOVNTDQ, MOVNTPS, and MOVNTPD); and
+ *   . string operations (see Section 8.2.4.1).
+ *  ...
+ * . Reads may be reordered with older writes to different locations but not
+ * with older writes to the same location.
+ * . Reads or writes cannot be reordered with I/O instructions,
+ * locked instructions, or serializing instructions.
+ * . Reads cannot pass earlier LFENCE and MFENCE instructions.
+ * . Writes ... cannot pass earlier LFENCE, SFENCE, and MFENCE instructions.
+ * . LFENCE instructions cannot pass earlier reads.
+ * . SFENCE instructions cannot pass earlier writes ...
+ * . MFENCE instructions cannot pass earlier reads, writes ...
+ *
+ * As pointed by Java guys, that makes possible to use lock-prefixed
+ * instructions to get the same effect as mfence and on most modern HW
+ * that gives a better perfomance then using mfence:
+ * https://shipilev.net/blog/2014/on-the-fence-with-dependencies/

- *
- * Retrieve a burst of input packets from a receive queue of an Ethernet
- * device. The retrieved packets are stored in *rte_mbuf* structures whose
- * pointers are supplied in the *rx_pkts* array.
- *
- * 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 caller
- *   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
- * upper-level application might check the status of the device link once
- * being systematically returned a 0 value for a given number of tries.
- *
- * @param port_id
- *   The port identifier of the Ethernet device.
- * @param queue_id
- *   The index of the receive queue from which to retrieve input packets.
- *   The value must be in the range [0, nb_rx_queue - 1] previously supplied
- *   to rte_eth_dev_configure().
- * @param rx_pkts
- *   The address of an array of pointers to *rte_mbuf* structures that
- *   must be large enough to store *nb_pkts* pointers in it.
- * @param nb_pkts
- *   The maximum number of packets to retrieve.
- * @return
- *   The number of packets actually retrieved, which is the number
- *   of pointers to *rte_mbuf* structures effectively supplied to the
- *   *rx_pkts* array.

- * 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, each of them
- * allocated from a pool created with rte_pktmbuf_pool_create().
- * 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.
- *
- * If the PMD is DEV_TX_OFFLOAD_MT_LOCKFREE capable, multiple threads can
- * invoke this function concurrently on the same tx queue without SW lock.
- * @see rte_eth_dev_info_get, struct rte_eth_txconf::txq_flags

- *   to rte_eth_dev_configure().
- * @param tx_pkts
- *   The address of an array of *nb_pkts* pointers to *rte_mbuf* structures

+ * Retrieve a burst of input packets from a receive queue of an Ethernet
+ * device. The retrieved packets are stored in *rte_mbuf* structures whose
+ * pointers are supplied in the *rx_pkts* array.
+ *
+ * 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 caller
+ *   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
+ * upper-level application might check the status of the device link once
+ * being systematically returned a 0 value for a given number of tries.
+ *
+ * @param port_id
+ *   The port identifier of the Ethernet device.

+ *   The index of the receive queue from which to retrieve input packets.

+ *   to rte_eth_dev_configure().
+ * @param rx_pkts
+ *   The address of an array of pointers to *rte_mbuf* structures that
+ *   must be large enough to store *nb_pkts* pointers in it.
+ * @param nb_pkts

+ * 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, each of them
+ * allocated from a pool created with rte_pktmbuf_pool_create().
+ * 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.
+ *
+ * If the PMD is DEV_TX_OFFLOAD_MT_LOCKFREE capable, multiple threads can
+ * invoke this function concurrently on the same tx queue without SW lock.
