11 * **Added function to check primary process state.**
13 A new function ``rte_eal_primary_proc_alive()`` has been added
14 to allow the user to detect if a primary process is running.
15 Use cases for this feature include fault detection, and monitoring
16 using secondary processes.
18 * **Enabled bulk allocation of mbufs.**
20 A new function ``rte_pktmbuf_alloc_bulk()`` has been added to allow the user
21 to bulk allocate mbufs.
23 * **Added device link speed capabilities.**
25 The structure ``rte_eth_dev_info`` now has a ``speed_capa`` bitmap, which
26 allows the application to determine the supported speeds of each device.
28 * **Added bitmap of link speeds to advertise.**
30 Added a feature to allow the definition of a set of advertised speeds for auto-negotiation,
31 explicitly disabling link auto-negotiation (single speed)
32 and full auto-negotiation.
34 * **Added new poll-mode driver for Amazon Elastic Network Adapters (ENA).**
36 The driver operates for a variety of ENA adapters through feature negotiation
37 with the adapter and upgradable commands set.
38 The ENA driver handles PCI Physical and Virtual ENA functions.
40 * **Restored vmxnet3 TX data ring.**
42 TX data ring has been shown to improve small packet forwarding performance
43 on the vSphere environment.
45 * **Added vmxnet3 TX L4 checksum offload.**
47 Added support for TCP/UDP checksum offload to vmxnet3.
49 * **Added vmxnet3 TSO support.**
51 Added support for TSO to vmxnet3.
53 * **Added vmxnet3 support for jumbo frames.**
55 Added support for linking multi-segment buffers together to
58 * **Enabled Virtio 1.0 support.**
60 Enabled Virtio 1.0 support for Virtio pmd driver.
62 * **Supported Virtio for ARM.**
64 Enabled Virtio support for ARMv7/v8. Tested for ARM64.
65 Virtio for ARM supports VFIO-noiommu mode only.
66 Virtio can work with other non-x86 architectures as well, like PowerPC.
68 * **Supported Virtio offload in vhost-user.**
70 Added the offload and negotiation of checksum and TSO between vhost-user and
71 vanilla Linux Virtio guest.
73 * **Added vhost-user live migration support.**
75 * **Added vhost driver.**
77 Added a virtual PMD that wraps ``librte_vhost``.
79 * **Added multicast promiscuous mode support on VF for ixgbe.**
81 Added multicast promiscuous mode support for the ixgbe VF driver so all VFs
82 can receive the multicast packets.
84 Please note if you want to use this promiscuous mode, you need both PF and VF
85 driver to support it. The reason is that this VF feature is configured in the PF.
86 If you use kernel PF driver and the dpdk VF driver, make sure the kernel PF driver supports
87 VF multicast promiscuous mode. If you use dpdk PF and dpdk VF ensure the PF
88 driver is the same version as the VF.
90 * **Added support for E-tag on X550.**
92 E-tag is defined in `802.1BR - Bridge Port Extension <http://www.ieee802.org/1/pages/802.1br.html>`_.
94 This feature is for the VF, but the settings are on the PF. It means
95 the CLIs should be used on the PF, but some of their effects will be shown on the VF.
96 The forwarding of E-tag packets based on GRP and E-CID_base will have an effect
97 on the PF. Theoretically, the E-tag packets can be forwarded to any pool/queue
98 but normally we'd like to forward the packets to the pools/queues belonging
99 to the VFs. And E-tag insertion and stripping will have an effect on VFs. When
100 a VF receives E-tag packets it should strip the E-tag. When the VF transmits
101 packets, it should insert the E-tag. Both actions can be offloaded.
103 When we want to use this E-tag support feature, the forwarding should be
104 enabled to forward the packets received by the PF to the indicated VFs. And insertion
105 and stripping should be enabled for VFs to offload the effort to hardware.
109 * Support E-tag offloading of insertion and stripping.
110 * Support Forwarding E-tag packets to pools based on
113 * **Added support for VxLAN and NVGRE checksum off-load on X550.**
115 * Added support for VxLAN and NVGRE RX/TX checksum off-load on
116 X550. RX/TX checksum off-load is provided on both inner and
117 outer IP header and TCP header.
118 * Added functions to support VxLAN port configuration. The
119 default VxLAN port number is 4789 but this can be updated
122 * **Added support for new X550EM_a devices.**
124 Added support for new X550EM_a devices and their MAC types, X550EM_a and X550EM_a_vf.
125 Updated the relevant PMD to use the new devices and MAC types.
127 * **Added x550em_x V2 device support.**
129 Added support for x550em_x V2 device. Only x550em_x V1 was supported before.
130 A mask for V1 and V2 is defined and used to support both.
132 * **Supported link speed auto-negotiation on X550EM_X**
134 Normally the auto-negotiation is supported by firmware and software doesn't care about
135 it. But on x550em_x, firmware doesn't support auto-negotiation. As the ports of x550em_x
136 are 10GbE, if we connect the port with a peer which is 1GbE, the link will always
138 We added the support for auto-negotiation by software to avoid this link down issue.
140 * **Added software-firmware sync on X550EM_a.**
142 Added support for software-firmware sync for resource sharing.
143 Use the PHY token, shared between software-firmware for PHY access on X550EM_a.
145 * **Updated the i40e base driver.**
147 The i40e base driver was updated with changes including the
150 * Use RX control AQ commands to read/write RX control registers.
151 * Add new X722 device IDs, and removed X710 one was never used.
152 * Expose registers for HASH/FD input set configuring.
154 * **Enabled PCI extended tag for i40e.**
156 Enabled extended tag for i40e by checking and writing corresponding PCI config
157 space bytes, to boost the performance.
158 The legacy method of reading/writing sysfile supported by kernel module igb_uio
161 * **Added i40e support for setting mac addresses.**
163 * **Added dump of i40e registers and EEPROM.**
165 * **Supported ether type setting of single and double VLAN for i40e**
167 * **Added VMDQ DCB mode in i40e.**
169 Added support for DCB in VMDQ mode to i40e driver.
171 * **Added i40e VEB switching support.**
173 * **Added Flow director enhancements in i40e.**
175 * **Added PF reset event reporting in i40e VF driver.**
177 * **Added fm10k RX interrupt support.**
179 * **Optimized fm10k TX.**
181 Optimized fm10k TX by freeing multiple mbufs at a time.
183 * **Handled error flags in fm10k vector RX.**
185 Parse error flags in RX descriptor and set error bits in mbuf with vector instructions.
187 * **Added fm10k FTAG based forwarding support.**
189 * **Added mlx5 flow director support.**
191 Added flow director support (``RTE_FDIR_MODE_PERFECT`` and
192 ``RTE_FDIR_MODE_PERFECT_MAC_VLAN``).
194 Only available with Mellanox OFED >= 3.2.
196 * **Added mlx5 RX VLAN stripping support.**
198 Added support for RX VLAN stripping.
200 Only available with Mellanox OFED >= 3.2.
202 * **Added mlx5 link up/down callbacks.**
204 Implemented callbacks to bring link up and down.
206 * **Added mlx5 support for operation in secondary processes.**
208 Implemented TX support in secondary processes (like mlx4).
210 * **Added mlx5 RX CRC stripping configuration.**
212 Until now, CRC was always stripped. It can now be configured.
214 Only available with Mellanox OFED >= 3.2.
216 * **Added mlx5 optional packet padding by HW.**
218 Added an option to make PCI bus transactions rounded to a multiple of a
219 cache line size for better alignment.
221 Only available with Mellanox OFED >= 3.2.
223 * **Added mlx5 TX VLAN insertion support.**
225 Added support for TX VLAN insertion.
227 Only available with Mellanox OFED >= 3.2.
229 * **Changed szedata2 driver type from vdev to pdev.**
231 Previously szedata2 device had to be added by ``--vdev`` option.
232 Now szedata2 PMD recognizes the device automatically during EAL
235 * **Added szedata2 functions for setting link up/down.**
237 * **Added szedata2 promiscuous and allmulticast modes.**
239 * **Added af_packet dynamic removal function.**
241 An af_packet device can now be detached using the API, like other PMD devices.
243 * **Increased number of next hops for LPM IPv4 to 2^24.**
245 The ``next_hop`` field has been extended from 8 bits to 24 bits for IPv4.
247 * **Added support of SNOW 3G (UEA2 and UIA2) for Intel Quick Assist devices.**
249 Enabled support for the SNOW 3G wireless algorithm for Intel Quick Assist devices.
250 Support for cipher-only and hash-only is also provided
251 along with algorithm-chaining operations.
253 * **Added SNOW3G SW PMD.**
255 A new Crypto PMD has been added, which provides SNOW 3G UEA2 ciphering
256 and SNOW3G UIA2 hashing.
258 * **Added AES GCM PMD.**
260 Added new Crypto PMD to support AES-GCM authenticated encryption and
261 authenticated decryption in software.
263 * **Added NULL Crypto PMD**
265 Added new Crypto PMD to support null crypto operations in software.
267 * **Improved IP Pipeline Application.**
269 The following features have been added to ip_pipeline application;
271 * Added CPU utilization measurement and idle cycle rate computation.
272 * Added link identification support through existing port-mask option or by
273 specifying PCI device in every LINK section in the configuration file.
274 * Added load balancing support in passthrough pipeline.
276 * **Added IPsec security gateway example.**
278 Added a new application implementing an IPsec Security Gateway.
287 * **ethdev: Fixed overflow for 100Gbps.**
289 100Gbps in Mbps (100000) was exceeding the 16-bit max value of ``link_speed``
292 * **ethdev: Fixed byte order consistency between fdir flow and mask.**
294 Fixed issue in ethdev library where the structure for setting
295 fdir's mask and flow entry was not consistent in byte ordering.
297 * **cxgbe: Fixed crash due to incorrect size allocated for RSS table.**
299 Fixed a segfault that occurs when accessing part of port 0's RSS
300 table that gets overwritten by subsequent port 1's part of the RSS
301 table due to incorrect size allocated for each entry in the table.
303 * **cxgbe: Fixed setting wrong device MTU.**
305 Fixed an incorrect device MTU being set due to the Ethernet header and
306 CRC lengths being added twice.
308 * **ixgbe: Fixed zeroed VF mac address.**
310 Resolved an issue where the VF MAC address is zeroed out in cases where the VF
311 driver is loaded while the PF interface is down.
312 The solution is to only set it when we get an ACK from the PF.
314 * **ixgbe: Fixed setting flow director flag twice.**
316 Resolved an issue where packets were being dropped when switching to perfect
319 * **ixgbe: Set MDIO speed after MAC reset.**
321 The MDIO clock speed must be reconfigured after the MAC reset. The MDIO clock
322 speed becomes invalid, therefore the driver reads invalid PHY register values.
323 The driver now set the MDIO clock speed prior to initializing PHY ops and
324 again after the MAC reset.
326 * **ixgbe: Fixed maximum number of available TX queues.**
328 In IXGBE, the maximum number of TX queues varies depending on the NIC operating
329 mode. This was not being updated in the device information, providing
330 an incorrect number in some cases.
332 * **i40e: Generated MAC address for each VFs.**
334 It generates a MAC address for each VFs during PF host initialization,
335 and keeps the VF MAC address the same among different VF launch.
337 * **i40e: Fixed failure of reading/writing RX control registers.**
339 Fixed i40e issue of failing to read/write rx control registers when
340 under stress with traffic, which might result in application launch
343 * **i40e: Enabled vector driver by default.**
345 Previously, vector driver was disabled by default as it couldn't fill packet type
346 info for l3fwd to work well. Now there is an option for l3fwd to analyze
347 the packet type so the vector driver is enabled by default.
349 * **i40e: Fixed link info of VF.**
351 Previously, the VF's link speed stayed at 10GbE and status always was up.
352 It did not change even when the physical link's status changed.
353 Now this issue is fixed to make VF's link info consistent with physical link.
355 * **mlx5: Fixed possible crash during initialization.**
357 A crash could occur when failing to allocate private device context.
359 * **mlx5: Added port type check.**
361 Added port type check to prevent port initialization on non-Ethernet link layers and
364 * **mlx5: Applied VLAN filtering to broadcast and IPv6 multicast flows.**
366 Prevented reception of multicast frames outside of configured VLANs.
368 * **mlx5: Fixed RX checksum offload in non L3/L4 packets.**
370 Fixed report of bad checksum for packets of unknown type.
372 * **aesni_mb: Fixed wrong return value when creating a device.**
374 The ``cryptodev_aesni_mb_init()`` function was returning the device id of the device created,
375 instead of 0 (on success) that ``rte_eal_vdev_init()`` expects.
376 This made it impossible to create more than one aesni_mb device
377 from the command line.
379 * **qat: Fixed AES GCM decryption.**
381 Allowed AES GCM on the cryptodev API, but in some cases gave invalid results
382 due to incorrect IV setting.
388 * **hash: Fixed CRC32c hash computation for non multiple of 4 bytes sizes.**
390 Fix crc32c hash functions to return a valid crc32c value for data lengths
391 not a multiple of 4 bytes.
393 * **hash: Fixed hash library to support multi-process mode.**
395 Fix hash library to support multi-process mode, using a jump table,
396 instead of storing a function pointer to the key compare function.
397 Multi-process mode only works with the built-in compare functions,
398 however a custom compare function (not in the jump table) can only
399 be used in single-process mode.
401 * **hash: Fixed return value when allocating an existing hash table.**
403 Changed the ``rte_hash*_create()`` functions to return ``NULL`` and set
404 ``rte_errno`` to ``EEXIST`` when the object name already exists. This is
405 the behavior described in the API documentation in the header file.
406 The previous behavior was to return a pointer to the existing object in
407 that case, preventing the caller from knowing if the object had to be freed
410 * **lpm: Fixed return value when allocating an existing object.**
412 Changed the ``rte_lpm*_create()`` functions to return ``NULL`` and set
413 ``rte_errno`` to ``EEXIST`` when the object name already exists. This is
414 the behavior described in the API documentation in the header file.
415 The previous behavior was to return a pointer to the existing object in
416 that case, preventing the caller from knowing if the object had to be freed
419 * **librte_port: Fixed segmentation fault for ring and ethdev writer nodrop.**
421 Fixed core dump issue on txq and swq when dropless is set to yes.
427 * **l3fwd-power: Fixed memory leak for non-IP packet.**
429 Fixed issue in l3fwd-power where, on receiving packets of types
430 other than IPv4 or IPv6, the mbuf was not released, and caused
433 * **l3fwd: Fixed using packet type blindly.**
435 l3fwd makes use of packet type information without querying if devices or PMDs
436 really set it. For those devices that don't set ptypes, add an option to parse it.
438 * **examples/vhost: Fixed frequent mbuf allocation failure.**
440 The vhost-switch often fails to allocate mbuf when dequeue from vring because it
441 wrongly calculates the number of mbufs needed.
447 * The ethdev statistics counter ``imissed`` is considered to be independent of ``ierrors``.
448 All drivers are now counting the missed packets only once, i.e. drivers will
449 not increment ierrors anymore for missed packets.
451 * The ethdev structure ``rte_eth_dev_info`` was changed to support device
454 * The ethdev structures ``rte_eth_link`` and ``rte_eth_conf`` were changed to
455 support the new link API.
457 * The functions ``rte_eth_dev_udp_tunnel_add`` and ``rte_eth_dev_udp_tunnel_delete``
458 have been renamed into ``rte_eth_dev_udp_tunnel_port_add`` and
459 ``rte_eth_dev_udp_tunnel_port_delete``.
461 * The ``outer_mac`` and ``inner_mac`` fields in structure
462 ``rte_eth_tunnel_filter_conf`` are changed from pointer to struct in order
463 to keep code's readability.
465 * The fields in ethdev structure ``rte_eth_fdir_masks`` were changed
468 * A parameter ``vlan_type`` has been added to the function
469 ``rte_eth_dev_set_vlan_ether_type``.
471 * The af_packet device init function is no longer public. The device should be attached
474 * The LPM ``next_hop`` field is extended from 8 bits to 24 bits for IPv4
475 while keeping ABI compatibility.
477 * A new ``rte_lpm_config`` structure is used so the LPM library will allocate
478 exactly the amount of memory which is necessary to hold application’s rules.
479 The previous ABI is kept for compatibility.
481 * The prototype for the pipeline input port, output port and table action
482 handlers are updated: the pipeline parameter is added,
483 the packets mask parameter has been either removed or made input-only.
489 * The RETA entry size in ``rte_eth_rss_reta_entry64`` has been increased
490 from 8-bit to 16-bit.
492 * The ethdev flow director structure ``rte_eth_fdir_flow`` structure was
493 changed. New fields were added to extend flow director's input set.
495 * The cmdline buffer size has been increase from 256 to 512.
