This patch changes it, and use uint16_t as port identifier. This patch only changes ethdev library. ABI of the library will be kept even after applying it. Also, this patch involves following fixes. - Use "port_id" as variable name instead of "port".

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 + +#include +#include +#include +#include +#include "rte_ether.h" +#include "rte_eth_ctrl.h" + +/** + * A structure used to retrieve statistics for an Ethernet port. + */ +struct rte_eth_stats { + uint64_t ipackets;
