16 a ring if it was created with ``rte_ring_create()``.
18 * **Added keepalive support to EAL and example application.**
20 * **Added experimental cryptodev API**
22 The cryptographic processing of packets is provided as a preview
25 * Intel QuickAssist devices

28 Due to its experimental state, the API may change without prior notice.
30 * **Added ethdev APIs for additional IEEE1588 support.**
32 Added functions to read, write and adjust system time in the NIC.
33 Added client slave sample application to demonstrate the IEEE1588
36 * **Extended Statistics.**
38 Defined an extended statistics naming scheme to store metadata in the name
39 string of each statistic. Refer to the Extended Statistics section of the
40 Programmers Guide for more details.
42 Implemented the extended statistics API for the following PMDs:
51 * **Added API in ethdev to retrieve RX/TX queue information.**
53 * Added the ability for the upper layer to query RX/TX queue information.
54 * Added new fields in ``rte_eth_dev_info`` to represent information about
55 RX/TX descriptors min/max/align numbers, per queue, for the device.
57 * **Added RSS dynamic configuration to bonding.**
59 * **Updated the e1000 base driver.**
61 The e1000 base driver was updated with several features including the

90 * **Updated the i40e base driver.**
92 The i40e base driver was updated with several changes including the
95 * Added promiscuous on VLAN support
96 * Added a workaround to drop all flow control frames
97 * Added VF capabilities to virtual channel interface
98 * Added TX Scheduling related AQ commands

111 * **Added DCB support to i40e PF driver.**
113 * **Added RSS/FD input set granularity on Intel X710/XL710.**
115 * **Added different GRE key length for input set on Intel X710/XL710.**
117 * **Added flow director support in i40e VF.**
119 * **Added i40e support of early X722 series.**
121 Added early X722 support, for evaluation only, as the hardware is alpha.
123 * **Added fm10k vector RX/TX.**
125 * **Added fm10k TSO support for both PF and VF.**
127 * **Added fm10k VMDQ support.**
129 * **New NIC Boulder Rapid support.**

136 * Optimized forwarding performance for Chelsio T5 40GbE cards.
138 * **Improved enic TX packet rate.**
140 Reduced frequency of TX tail pointer updates to the NIC.
142 * **Added support for link status interrupts in mlx4.**
144 * **Added partial support (TX only) for secondary processes in mlx4.**
146 * **Added support for Mellanox ConnectX-4 adapters (mlx5).**
148 The mlx5 poll-mode driver implements support for Mellanox ConnectX-4 EN
149 and Mellanox ConnectX-4 Lx EN families of 10/25/40/50/100 Gb/s adapters.
151 Like mlx4, this PMD is only available for Linux and is disabled by default
152 due to external dependencies (libibverbs and libmlx5).
154 * **Added driver for Netronome nfp-6xxx card.**
156 Support for using Netronome nfp-6xxx with PCI VFs.
158 * **Added virtual szedata2 driver for COMBO cards.**
160 Added virtual PMD for COMBO-100G and COMBO-80G cards.
161 PMD is disabled in default configuration.
163 * **Enhanced support for virtio driver.**
165 * Virtio ring layout optimization (fixed avail ring)
169 * **Added vhost-user multiple queue support.**
171 * **Added port hotplug support to vmxnet3.**
173 * **Added port hotplug support to xenvirt.**
175 * **Added ethtool shim and sample application.**
177 * **Added experimental performance thread example application.**
179 The new sample application demonstrates L3 forwarding with different threading
180 models: pthreads, cgroups, or lightweight threads. The example includes
181 a simple cooperative scheduler.
183 Due to its experimental state this application may change without notice.
184 The application is supported only for Linux x86_64.
186 * **Enhancements to the IP pipeline application.**
188 The following features have been added to the ``ip_pipeline``
191 * Added Multiple Producers/Multiple Consumers (MPSC)
192 and fragmentation/reassembly support to software rings.
194 * Added a dynamic pipeline reconfiguration feature that
195 allows binding a pipeline to other threads at runtime
198 * Added enable/disable of ``promisc`` mode from ``ip_pipeline``
201 * Added check on RX queues and TX queues of each link
202 whether they are used correctly in the ``ip_pipeline``
205 * Added flow id parameters to the flow-classification
208 * Added more functions to the routing pipeline:
209 ARP table enable/disable, Q-in-Q and MPLS encapsulation,
210 add color (traffic-class for QoS) to the MPLS tag.
212 * Added flow-actions pipeline for traffic metering/marking
213 (for e.g. Two Rate Three Color Marker (trTCM)), policer etc.
215 * Modified the pass-through pipeline's actions-handler to
216 implement a generic approach to extract fields from the
217 packet's header and copy them to packet metadata.
226 * **eal/linux: Fixed epoll timeout.**
228 Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
229 underlying call to ``epoll_wait()`` timed out.
235 * **e1000/base: Synchronize PHY interface on non-ME systems.**
237 On power up, the MAC - PHY interface needs to be set to PCIe, even if the
238 cable is disconnected. In ME systems, the ME handles this on exit from the
239 Sx (Sticky mode) state. In non-ME, the driver handles it. Added a check for
240 non-ME system to the driver code that handles it.
242 * **e1000/base: Increased timeout of reset check.**
244 Previously, in ``check_reset_block`` RSPCIPHY was polled for 100 ms before
245 determining that the ME veto was set. This was not enough and it was
248 * **e1000/base: Disabled IPv6 extension header parsing on 82575.**
250 Disabled IPv6 options as per hardware limitation.
252 * **e1000/base: Prevent ULP flow if cable connected.**
254 Enabling ULP on link down when the cable is connected caused an infinite
255 loop of link up/down indications in the NDIS driver.
256 The driver now enables ULP only when the cable is disconnected.
258 * **e1000/base: Support different EEARBC for i210.**
260 EEARBC has changed on i210. It means EEARBC has a different address on
261 i210 than on other NICs. So, add a new entity named EEARBC_I210 to the
262 register list and make sure the right one is being used on i210.
264 * **e1000/base: Fix K1 configuration.**
266 Added fix for the following updates to the K1 configurations:
267 TX idle period for entering K1 should be 128 ns.
268 Minimum TX idle period in K1 should be 256 ns.
270 * **e1000/base: Fix link detect flow.**
272 Fix link detect flow in case where auto-negotiate is not enabled, by calling
273 ``e1000_setup_copper_link_generic`` instead of ``e1000_phy_setup_autoneg``.
275 * **e1000/base: Fix link check for i354 M88E1112 PHY.**
277 The ``e1000_check_for_link_media_swap()`` function is supposed to check PHY
278 page 0 for copper and PHY page 1 for "other" (fiber) links. The driver
279 switched back from page 1 to page 0 too soon, before
280 ``e1000_check_for_link_82575()`` is executed and was never finding the link
281 on the fiber (other).
283 If the link is copper, as the M88E1112 page address is set to 1, it should be
284 set back to 0 before checking this link.
286 * **e1000/base: Fix beacon duration for i217.**
288 Fix for I217 Packet Loss issue - The Management Engine sets the FEXTNVM4
289 Beacon Duration incorrectly. This fix ensures that the correct value will
290 always be set. Correct value for this field is 8 usec.
292 * **e1000/base: Fix TIPG for non 10 half duplex mode.**
294 TIPG value is increased when setting speed to 10 half duplex to prevent
295 packet loss. However, it was never decreased again when speed
296 changed. This caused performance issues in the NDIS driver.
297 Fix this to restore TIPG to default value on non 10 half duplex.
299 * **e1000/base: Fix reset of DH89XXCC SGMII.**
301 For DH89XXCC_SGMII, a write flush leaves registers of this device trashed
302 (0xFFFFFFFF). Add check for this device.
304 Also, after both Port SW Reset and Device Reset case, the platform should
305 wait at least 3ms before reading any registers. Remove this condition since
306 waiting is conditionally executed only for Device Reset.
308 * **e1000/base: Fix redundant PHY power down for i210.**
310 Bit 11 of PHYREG 0 is used to power down PHY. The use of PHYREG 16 is
313 * **e1000/base: fix jumbo frame CRC failures.**
315 Change the value of register 776.20[11:2] for jumbo mode from 0x1A to 0x1F.
316 This is to enlarge the gap between read and write pointers in the TX FIFO.
318 * **e1000/base: Fix link flap on 82579.**
320 Several customers have reported a link flap issue on 82579. The symptoms
321 are random and intermittent link losses when 82579 is connected to specific
322 switches. the Issue was root caused as an inter-operability problem between
323 the NIC and at least some Broadcom PHYs in the Energy Efficient Ethernet
326 To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M
327 Low Power Idle. This solution will cause an increase of power in 100M EEE
328 link. It may cost an additional 28mW in this specific mode.
330 * **igb: Fixed IEEE1588 frame identification in I210.**
332 Fixed issue where the flag ``PKT_RX_IEEE1588_PTP`` was not being set
333 in the Intel I210 NIC, as the EtherType in RX descriptor is in bits 8:10 of
334 Packet Type and not in the default bits 0:2.
336 * **igb: Fixed VF start with PF stopped.**
338 VF needs the PF interrupt support initialized even if not started.
340 * **igb: Fixed VF MAC address when using with DPDK PF.**
342 Assign a random MAC address in VF when not assigned by PF.
344 * **igb: Removed CRC bytes from byte counter statistics.**
346 * **ixgbe: Fixed issue with X550 DCB.**
348 Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
349 with user priority 6 or 7 was injected to the NIC, then the NIC would only
350 put 3 packets into the queue. There was also a similar issue for 4 TCs.
352 * **ixgbe: Removed burst size restriction of vector RX.**
354 Fixed issue where a burst size less than 32 didn't receive anything.
356 * **ixgbe: Fixed VF start with PF stopped.**
358 VF needs the PF interrupt support initialized even if not started.
360 * **ixgbe: Fixed TX hang when RS distance exceeds HW limit.**
362 Fixed an issue where the TX queue can hang when a lot of highly fragmented
363 packets have to be sent. As part of that fix, ``tx_rs_thresh`` for ixgbe PMD
364 is not allowed to be greater then to 32 to comply with HW restrictions.
366 * **ixgbe: Fixed rx error statistic counter.**
368 Fixed an issue that the rx error counter of ixgbe was not accurate. The
369 mac short packet discard count (mspdc) was added to the counter. Mac local
370 faults and mac remote faults are removed as they do not count packets but
371 errors, and jabber errors were removed as they are already accounted for
372 by the CRC error counter. Finally the XEC (l3 / l4 checksum error) counter
373 was removed due to errata, see commit 256ff05a9cae for details.
375 * **ixgbe: Removed CRC bytes from byte counter statistics.**
377 * **i40e: Fixed base driver allocation when not using first numa node.**
379 Fixed i40e issue that occurred when a DPDK application didn't initialize
380 ports if memory wasn't available on socket 0.
382 * **i40e: Fixed maximum of 64 queues per port.**
384 Fixed an issue in i40e where it would not support more than 64 queues per
385 port, even though the hardware actually supports it. The real number of
386 queues may vary, as long as the total number of queues used in PF, VFs, VMDq
387 and FD does not exceeds the hardware maximum.
389 * **i40e: Fixed statistics of packets.**
391 Added discarding packets on VSI to the stats and rectify the old statistics.
393 * **i40e: Fixed issue of not freeing memzone.**
395 Fixed an issue of not freeing a memzone in the call to free the memory for
398 * **i40e: Removed CRC bytes from byte counter statistics.**
400 * **mlx: Fixed driver loading.**
402 The mlx drivers were unable to load when built as a shared library,
403 due to a missing symbol in the mempool library.
405 * **mlx4: Performance improvements.**
407 Fixed bugs in TX and RX flows that improves mlx4 performance.
409 * **mlx4: Fixed TX loss after initialization.**
411 * **mlx4: Fixed scattered TX with too many segments.**
413 * **mlx4: Fixed memory registration for indirect mbuf data.**
415 * **vhost: Fixed Qemu shutdown.**
417 Fixed issue with libvirt ``virsh destroy`` not killing the VM.
419 * **virtio: Fixed crash after changing link state.**
421 Fixed IO permission in the interrupt handler.
423 * **virtio: Fixed crash when releasing queue.**
425 Fixed issue when releasing null control queue.
431 * **hash: Fixed memory allocation of Cuckoo Hash key table.**
433 Fixed issue where an incorrect Cuckoo Hash key table size could be
434 calculated limiting the size to 4GB.
436 * **hash: Fixed incorrect lookup if key is all zero.**
438 Fixed issue in hash library that occurred if an all zero
439 key was not added to the table and the key was looked up,
440 resulting in an incorrect hit.
442 * **hash: Fixed thread scaling by reducing contention.**
444 Fixed issue in the hash library where, using multiple cores with
445 hardware transactional memory support, thread scaling did not work,
446 due to the global ring that is shared by all cores.
452 * **l3fwd: Fixed crash with IPv6.**
454 * **vhost_xen: Fixed compile error.**
460 * This release drops compatibility with Linux kernel 2.6.33. The minimum
461 kernel requirement is now 2.6.34.
467 * Some drivers do not fill in the packet type when receiving.
468 As the l3fwd example application requires this info, the i40e vector
469 driver must be disabled to benefit of the packet type with i40e.
471 * Some (possibly all) VF drivers (e.g. i40evf) do not handle any PF reset
472 events/requests in the VF driver. This means that the VF driver may not work
473 after a PF reset in the host side. The workaround is to avoid triggering any
474 PF reset events/requests on the host side.
476 * 100G link report support is missing.
478 * **Mellanox PMDs (mlx4 & mlx5):**
480 * PMDs do not support CONFIG_RTE_BUILD_COMBINE_LIBS and
481 CONFIG_RTE_BUILD_SHARED_LIB simultaneously.
483 * There is performance degradation for small packets when the PMD is
484 compiled with ``SGE_WR_N = 4`` compared to the performance when ``SGE_WR_N
485 = 1``. If scattered packets are not used it is recommended to compile the
486 PMD with ``SGE_WR_N = 1``.
488 * When a Multicast or Broadcast packet is sent to the SR-IOV mlx4 VF,
489 it is returned back to the port.
491 * PMDs report "bad" L4 checksum when IP packet is received.
493 * mlx5 PMD reports "bad" checksum although the packet has "good" checksum.
494 Will be fixed in upcoming MLNX_OFED release.
500 * The deprecated flow director API is removed.
501 It was replaced by ``rte_eth_dev_filter_ctrl()``.
503 * The ``dcb_queue`` is renamed to ``dcb_tc`` in following dcb configuration
504 structures: ``rte_eth_dcb_rx_conf``, ``rte_eth_dcb_tx_conf``,
505 ``rte_eth_vmdq_dcb_conf``, ``rte_eth_vmdq_dcb_tx_conf``.
507 * The ``rte_eth_rx_queue_count()`` function now returns "int" instead of
508 "uint32_t" to allow the use of negative values as error codes on return.
510 * The function ``rte_eal_pci_close_one()`` is removed.
511 It was replaced by ``rte_eal_pci_detach()``.
513 * The deprecated ACL API ``ipv4vlan`` is removed.
515 * The deprecated hash function ``rte_jhash2()`` is removed.
516 It was replaced by ``rte_jhash_32b()``.
518 * The deprecated KNI functions are removed:
519 ``rte_kni_create()``, ``rte_kni_get_port_id()`` and ``rte_kni_info_get()``.
521 * The deprecated ring PMD functions are removed:
522 ``rte_eth_ring_pair_create()`` and ``rte_eth_ring_pair_attach()``.
524 * The devargs union field ``virtual`` is renamed to ``virt`` for C++
531 * The EAL and ethdev structures ``rte_intr_handle`` and ``rte_eth_conf`` were
532 changed to support RX interrupt. This was already included in 2.1 under the
533 ``CONFIG_RTE_NEXT_ABI`` #define.
535 * The ethdev flow director entries for SCTP were changed.
536 This was already included in 2.1 under the ``CONFIG_RTE_NEXT_ABI`` #define.
538 * The ethdev flow director structure ``rte_eth_fdir_flow_ext`` structure was
539 changed. New fields were added to support flow director filtering in VF.
541 * The size of the ethdev structure ``rte_eth_hash_filter_info`` is changed
542 by adding a new element ``rte_eth_input_set_conf`` in a union.
544 * New fields ``rx_desc_lim`` and ``tx_desc_lim`` are added into
545 ``rte_eth_dev_info`` structure.
547 * For debug builds, the functions ``rte_eth_rx_burst()``, ``rte_eth_tx_burst()``
548 ``rte_eth_rx_descriptor_done()`` and ``rte_eth_rx_queue_count()`` will
549 no longer be separate functions in the DPDK libraries. Instead, they will
550 only be present in the ``rte_ethdev.h`` header file.
552 * The maximum number of queues per port ``CONFIG_RTE_MAX_QUEUES_PER_PORT`` is
555 * The mbuf structure was changed to support the unified packet type.
556 This was already included in 2.1 under the ``CONFIG_RTE_NEXT_ABI`` #define.
558 * The dummy malloc library is removed. The content was moved into EAL in 2.1.
560 * The LPM structure is changed. The deprecated field ``mem_location`` is
563 * librte_table LPM: A new parameter to hold the table name will be added to
564 the LPM table parameter structure.
566 * librte_table hash: The key mask parameter is added to the hash table
567 parameter structure for 8-byte key and 16-byte key extendable bucket
570 * librte_port: Macros to access the packet meta-data stored within the packet
571 buffer has been adjusted to cover the packet mbuf structure.
573 * librte_cfgfile: Allow longer names and values by increasing the constants
574 ``CFG_NAME_LEN`` and ``CFG_VALUE_LEN`` to 64 and 256 respectively.
576 * vhost: a new field enabled is added to the ``vhost_virtqueue`` structure.
578 * vhost: a new field ``virt_qp_nb`` is added to ``virtio_net`` structure, and
579 the ``virtqueue`` field is moved to the end of virtio_net structure.
581 * vhost: a new operation ``vring_state_changed`` is added to
582 ``virtio_net_device_ops`` structure.
584 * vhost: a few spaces are reserved both at ``vhost_virtqueue`` and
585 ``virtio_net`` structure for future extension.
