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. - */ - -#ifdef __cplusplus -extern "C" { -#endif - -#include <stdint.h> - -#include <rte_dev.h> - -/* Use this macro to check if LRO API is supported */ -#define RTE_ETHDEV_HAS_LRO_SUPPORT - -#include <rte_log.h> -#include <rte_interrupts.h> -#include <rte_pci.h> -#include <rte_dev.h> -#include <rte_devargs.h> -#include "rte_ether.h" -#include "rte_eth_ctrl.h" -#include "rte_dev_info.h" - -struct rte_mbuf;

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.
