41 * RTE Ethernet Device API
43 * The Ethernet Device API is composed of two parts:
45 * - The application-oriented Ethernet API that includes functions to setup
46 * an Ethernet device (configure it, setup its RX and TX queues and start it),
47 * to get its MAC address, the speed and the status of its physical link,
48 * to receive and to transmit packets, and so on.
50 * - The driver-oriented Ethernet API that exports a function allowing
51 * an Ethernet Poll Mode Driver (PMD) to simultaneously register itself as
52 * an Ethernet device driver and as a PCI driver for a set of matching PCI
53 * [Ethernet] devices classes.
55 * By default, all the functions of the Ethernet Device API exported by a PMD
56 * are lock-free functions which assume to not be invoked in parallel on
57 * different logical cores to work on the same target object. For instance,
58 * the receive function of a PMD cannot be invoked in parallel on two logical
59 * cores to poll the same RX queue [of the same port]. Of course, this function
60 * can be invoked in parallel by different logical cores on different RX queues.
61 * It is the responsibility of the upper level application to enforce this rule.
63 * If needed, parallel accesses by multiple logical cores to shared queues
64 * shall be explicitly protected by dedicated inline lock-aware functions
65 * built on top of their corresponding lock-free functions of the PMD API.
67 * In all functions of the Ethernet API, the Ethernet device is
68 * designated by an integer >= 0 named the device port identifier.
70 * At the Ethernet driver level, Ethernet devices are represented by a generic
71 * data structure of type *rte_eth_dev*.
73 * Ethernet devices are dynamically registered during the PCI probing phase
74 * performed at EAL initialization time.
75 * When an Ethernet device is being probed, an *rte_eth_dev* structure and
76 * a new port identifier are allocated for that device. Then, the eth_dev_init()
77 * function supplied by the Ethernet driver matching the probed PCI
78 * device is invoked to properly initialize the device.
80 * The role of the device init function consists of resetting the hardware,
81 * checking access to Non-volatile Memory (NVM), reading the MAC address
84 * If the device init operation is successful, the correspondence between
85 * the port identifier assigned to the new device and its associated
86 * *rte_eth_dev* structure is effectively registered.
87 * Otherwise, both the *rte_eth_dev* structure and the port identifier are
90 * The functions exported by the application Ethernet API to setup a device
91 * designated by its port identifier must be invoked in the following order:
92 * - rte_eth_dev_configure()
93 * - rte_eth_tx_queue_setup()
94 * - rte_eth_rx_queue_setup()
95 * - rte_eth_dev_start()
97 * Then, the network application can invoke, in any order, the functions
98 * exported by the Ethernet API to get the MAC address of a given device, to
99 * get the speed and the status of a device physical link, to receive/transmit
100 * [burst of] packets, and so on.
102 * If the application wants to change the configuration (i.e. call
103 * rte_eth_dev_configure(), rte_eth_tx_queue_setup(), or
104 * rte_eth_rx_queue_setup()), it must call rte_eth_dev_stop() first to stop the
105 * device and then do the reconfiguration before calling rte_eth_dev_start()
106 * again. The tramsit and receive functions should not be invoked when the
109 * Please note that some configuration is not stored between calls to
110 * rte_eth_dev_stop()/rte_eth_dev_start(). The following configuration will
113 * - flow control settings
114 * - receive mode configuration (promiscuous mode, hardware checksum mode,
115 * RSS/VMDQ settings etc.)
116 * - VLAN filtering configuration
117 * - MAC addresses supplied to MAC address array
118 * - flow director filtering mode (but not filtering rules)
119 * - NIC queue statistics mappings
121 * Any other configuration will not be stored and will need to be re-entered
122 * after a call to rte_eth_dev_start().
124 * Finally, a network application can close an Ethernet device by invoking the
125 * rte_eth_dev_close() function.
127 * Each function of the application Ethernet API invokes a specific function
128 * of the PMD that controls the target device designated by its port
130 * For this purpose, all device-specific functions of an Ethernet driver are
131 * supplied through a set of pointers contained in a generic structure of type
133 * The address of the *eth_dev_ops* structure is stored in the *rte_eth_dev*
134 * structure by the device init function of the Ethernet driver, which is
135 * invoked during the PCI probing phase, as explained earlier.
137 * In other words, each function of the Ethernet API simply retrieves the
138 * *rte_eth_dev* structure associated with the device port identifier and
139 * performs an indirect invocation of the corresponding driver function
140 * supplied in the *eth_dev_ops* structure of the *rte_eth_dev* structure.
142 * For performance reasons, the address of the burst-oriented RX and TX
143 * functions of the Ethernet driver are not contained in the *eth_dev_ops*
144 * structure. Instead, they are directly stored at the beginning of the
145 * *rte_eth_dev* structure to avoid an extra indirect memory access during
148 * RTE ethernet device drivers do not use interrupts for transmitting or
149 * receiving. Instead, Ethernet drivers export Poll-Mode receive and transmit
150 * functions to applications.
151 * Both receive and transmit functions are packet-burst oriented to minimize
152 * their cost per packet through the following optimizations:
154 * - Sharing among multiple packets the incompressible cost of the
155 * invocation of receive/transmit functions.
157 * - Enabling receive/transmit functions to take advantage of burst-oriented
158 * hardware features (L1 cache, prefetch instructions, NIC head/tail
159 * registers) to minimize the number of CPU cycles per packet, for instance,
160 * by avoiding useless read memory accesses to ring descriptors, or by
161 * systematically using arrays of pointers that exactly fit L1 cache line
162 * boundaries and sizes.
164 * The burst-oriented receive function does not provide any error notification,
165 * to avoid the corresponding overhead. As a hint, the upper-level application
166 * might check the status of the device link once being systematically returned
167 * a 0 value by the receive function of the driver for a given number of tries.

1657 * approach, avoiding the overhead of unnecessary intermediate packet
1658 * queue/dequeue operations.
1660 * - Conversely, it also allows an asynchronous-oriented processing
1661 * method to retrieve bursts of received packets and to immediately
1662 * queue them for further parallel processing by another logical core,
1663 * for instance. However, instead of having received packets being
1664 * individually queued by the driver, this approach allows the invoker
1665 * of the rte_eth_rx_burst() function to queue a burst of retrieved
1666 * packets at a time and therefore dramatically reduce the cost of
1667 * enqueue/dequeue operations per packet.
1669 * - It allows the rte_eth_rx_burst() function of the driver to take
1670 * advantage of burst-oriented hardware features (CPU cache,
1671 * prefetch instructions, and so on) to minimize the number of CPU
1672 * cycles per packet.

1676 * packet processing environments with no overhead in both cases.
