RTE Ethernet Device API
The Ethernet Device API is composed of two parts:
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:
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 transmit and receive functions should not be invoked when the device or the queue 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:
- MTU - flow control settings - receive mode configuration (promiscuous mode, all-multicast mode, hardware checksum mode, RSS/VMDQ settings etc.) - VLAN filtering configuration - default MAC address - 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 before 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:
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.

int rte_eth_dev_reset | ( | uint16_t | port_id | ) |
Reset a Ethernet device and keep its port id.
When a port has to be reset passively, the DPDK application can invoke this function. For example when a PF is reset, all its VFs should also be reset. Normally a DPDK application can invoke this function when RTE_ETH_EVENT_INTR_RESET event is detected, but can also use it to start a port reset in other circumstances.
When this function is called, it first stops the port and then calls the PMD specific dev_uninit( ) and dev_init( ) to return the port to initial state, in which no Tx and Rx queues are setup, as if the port has been reset and not started. The port keeps the port id it had before the function call.
After calling rte_eth_dev_reset( ), the application should use rte_eth_dev_configure( ), rte_eth_rx_queue_setup( ), rte_eth_tx_queue_setup( ), and rte_eth_dev_start( ) to reconfigure the device as appropriate.
Note: To avoid unexpected behavior, the application should stop calling Tx and Rx functions before calling rte_eth_dev_reset( ). For thread safety, all these controlling functions should be called from the same thread.

__rte_experimental int rte_eth_read_clock | ( | uint16_t | port_id, |
uint64_t * | clock | ||
) |
Read the current clock counter of an Ethernet device
This returns the current raw clock value of an Ethernet device. It is a raw amount of ticks, with no given time reference. The value returned here is from the same clock than the one filling timestamp field of Rx packets when using hardware timestamp offload. Therefore it can be used to compute a precise conversion of the device clock to the real time.
E.g, a simple heuristic to derivate the frequency would be: uint64_t start, end; rte_eth_read_clock(port, start); rte_delay_ms(100); rte_eth_read_clock(port, end); double freq = (end - start) * 10;
Compute a common reference with: uint64_t base_time_sec = current_time(); uint64_t base_clock; rte_eth_read_clock(port, base_clock);
Then, convert the raw mbuf timestamp with: base_time_sec + (double)(*timestamp_dynfield(mbuf) - base_clock) / freq;
This simple example will not provide a very good accuracy. One must at least measure multiple times the frequency and do a regression. To avoid deviation from the system time, the common reference can be repeated from time to time. The integer division can also be converted by a multiplication and a shift for better performance.

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:
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:
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.

Check the status of a Rx descriptor in the queue

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:
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.

Process a burst of output packets on a transmit queue of an Ethernet device.
The rte_eth_tx_prepare() function is invoked to prepare output packets to be transmitted 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 be prepared 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(). For each packet to send, the rte_eth_tx_prepare() function performs the following operations:
Since this function can modify packet data, provided mbufs must be safely writable (e.g. modified data cannot be in shared segment).
The rte_eth_tx_prepare() function returns the number of packets ready to be sent. A return value equal to nb_pkts means that all packets are valid and ready to be sent, otherwise stops processing on the first invalid packet and leaves the rest packets untouched.
When this functionality is not implemented in the driver, all packets are are returned untouched.

Send any packets queued up for transmission on a port and HW queue
This causes an explicit flush of packets previously buffered via the rte_eth_tx_buffer() function. It returns the number of packets successfully sent to the NIC, and calls the error callback for any unsent packets. Unless explicitly set up otherwise, the default callback simply frees the unsent packets back to the owning mempool.

Buffer a single packet for future transmission on a port and queue
This function takes a single mbuf/packet and buffers it for later transmission on the particular port and queue specified. Once the buffer is full of packets, an attempt will be made to transmit all the buffered packets. In case of error, where not all packets can be transmitted, a callback is called with the unsent packets as a parameter. If no callback is explicitly set up, the unsent packets are just freed back to the owning mempool. The function returns the number of packets actually sent i.e. 0 if no buffer flush occurred, otherwise the number of packets successfully flushed
