10 * **Added function to check primary process state.**
12 A new function ``rte_eal_primary_proc_alive()`` has been added
13 to allow the user to detect if a primary process is running.
14 Use cases for this feature include fault detection, and monitoring
15 using secondary processes.
17 * **Enabled bulk allocation of mbufs.**
19 A new function ``rte_pktmbuf_alloc_bulk()`` has been added to allow the user
20 to bulk allocate mbufs.
22 * **Added device link speed capabilities.**
24 The structure ``rte_eth_dev_info`` now has a ``speed_capa`` bitmap, which
25 allows the application to determine the supported speeds of each device.
27 * **Added bitmap of link speeds to advertise.**
29 Added a feature to allow the definition of a set of advertised speeds for auto-negotiation,
30 explicitly disabling link auto-negotiation (single speed)
31 and full auto-negotiation.
33 * **Added new poll-mode driver for Amazon Elastic Network Adapters (ENA).**
35 The driver operates for a variety of ENA adapters through feature negotiation
36 with the adapter and upgradable commands set.
37 The ENA driver handles PCI Physical and Virtual ENA functions.
39 * **Restored vmxnet3 TX data ring.**
41 TX data ring has been shown to improve small packet forwarding performance
42 on the vSphere environment.
44 * **Added vmxnet3 TX L4 checksum offload.**
46 Added support for TCP/UDP checksum offload to vmxnet3.
48 * **Added vmxnet3 TSO support.**
50 Added support for TSO to vmxnet3.
52 * **Added vmxnet3 support for jumbo frames.**
54 Added support for linking multi-segment buffers together to
57 * **Enabled Virtio 1.0 support.**
59 Enabled Virtio 1.0 support for Virtio PMD.
61 * **Supported Virtio for ARM.**
63 Enabled Virtio support for ARMv7/v8. Tested for ARM64.
64 Virtio for ARM supports VFIO-noiommu mode only.
65 Virtio can work with other non-x86 architectures as well, like PowerPC.
67 * **Supported Virtio offload in vhost-user.**
69 Added the offload and negotiation of checksum and TSO between vhost-user and
70 vanilla Linux Virtio guest.
72 * **Added vhost-user live migration support.**
74 * **Added vhost driver.**
76 Added a virtual PMD that wraps ``librte_vhost``.
78 * **Added multicast promiscuous mode support on VF for ixgbe.**
80 Added multicast promiscuous mode support for the ixgbe VF driver so all VFs
81 can receive the multicast packets.
83 Please note if you want to use this promiscuous mode, you need both PF and VF
84 driver to support it. The reason is that this VF feature is configured in the PF.
85 If you use kernel PF driver and the dpdk VF driver, make sure the kernel PF driver supports
86 VF multicast promiscuous mode. If you use dpdk PF and dpdk VF ensure the PF
87 driver is the same version as the VF.
89 * **Added support for E-tag on X550.**
91 E-tag is defined in `802.1BR - Bridge Port Extension <http://www.ieee802.org/1/pages/802.1br.html>`_.
93 This feature is for the VF, but the settings are on the PF. It means
94 the CLIs should be used on the PF, but some of their effects will be shown on the VF.
95 The forwarding of E-tag packets based on GRP and E-CID_base will have an effect
96 on the PF. Theoretically, the E-tag packets can be forwarded to any pool/queue
97 but normally we'd like to forward the packets to the pools/queues belonging
98 to the VFs. And E-tag insertion and stripping will have an effect on VFs. When
99 a VF receives E-tag packets it should strip the E-tag. When the VF transmits
100 packets, it should insert the E-tag. Both actions can be offloaded.
102 When we want to use this E-tag support feature, the forwarding should be
103 enabled to forward the packets received by the PF to the indicated VFs. And insertion
104 and stripping should be enabled for VFs to offload the effort to hardware.
108 * Support E-tag offloading of insertion and stripping.
109 * Support Forwarding E-tag packets to pools based on
112 * **Added support for VxLAN and NVGRE checksum off-load on X550.**
114 * Added support for VxLAN and NVGRE RX/TX checksum off-load on
115 X550. RX/TX checksum off-load is provided on both inner and
116 outer IP header and TCP header.
117 * Added functions to support VxLAN port configuration. The
118 default VxLAN port number is 4789 but this can be updated
121 * **Added support for new X550EM_a devices.**
123 Added support for new X550EM_a devices and their MAC types, X550EM_a and X550EM_a_vf.
124 Updated the relevant PMD to use the new devices and MAC types.
126 * **Added x550em_x V2 device support.**
128 Added support for x550em_x V2 device. Only x550em_x V1 was supported before.
129 A mask for V1 and V2 is defined and used to support both.
131 * **Supported link speed auto-negotiation on X550EM_X**
133 Normally the auto-negotiation is supported by firmware and software doesn't care about
134 it. But on x550em_x, firmware doesn't support auto-negotiation. As the ports of x550em_x
135 are 10GbE, if we connect the port with a peer which is 1GbE, the link will always
137 We added the support for auto-negotiation by software to avoid this link down issue.
139 * **Added software-firmware sync on X550EM_a.**
141 Added support for software-firmware sync for resource sharing.
142 Use the PHY token, shared between software-firmware for PHY access on X550EM_a.
144 * **Updated the i40e base driver.**
146 The i40e base driver was updated with changes including the
149 * Use RX control AQ commands to read/write RX control registers.
150 * Add new X722 device IDs, and removed X710 one was never used.
151 * Expose registers for HASH/FD input set configuring.
153 * **Enabled PCI extended tag for i40e.**
155 Enabled extended tag for i40e by checking and writing corresponding PCI config
156 space bytes, to boost the performance.
157 The legacy method of reading/writing sysfile supported by kernel module igb_uio
160 * **Added i40e support for setting mac addresses.**
162 * **Added dump of i40e registers and EEPROM.**
164 * **Supported ether type setting of single and double VLAN for i40e**
166 * **Added VMDQ DCB mode in i40e.**
168 Added support for DCB in VMDQ mode to i40e driver.
170 * **Added i40e VEB switching support.**
172 * **Added Flow director enhancements in i40e.**
174 * **Added PF reset event reporting in i40e VF driver.**
176 * **Added fm10k RX interrupt support.**
178 * **Optimized fm10k TX.**
180 Optimized fm10k TX by freeing multiple mbufs at a time.
182 * **Handled error flags in fm10k vector RX.**
184 Parse error flags in RX descriptor and set error bits in mbuf with vector instructions.
186 * **Added fm10k FTAG based forwarding support.**
188 * **Added mlx5 flow director support.**
190 Added flow director support (``RTE_FDIR_MODE_PERFECT`` and
191 ``RTE_FDIR_MODE_PERFECT_MAC_VLAN``).
193 Only available with Mellanox OFED >= 3.2.
195 * **Added mlx5 RX VLAN stripping support.**
197 Added support for RX VLAN stripping.
199 Only available with Mellanox OFED >= 3.2.
201 * **Added mlx5 link up/down callbacks.**
203 Implemented callbacks to bring link up and down.
205 * **Added mlx5 support for operation in secondary processes.**
207 Implemented TX support in secondary processes (like mlx4).
209 * **Added mlx5 RX CRC stripping configuration.**
211 Until now, CRC was always stripped. It can now be configured.
213 Only available with Mellanox OFED >= 3.2.
215 * **Added mlx5 optional packet padding by HW.**
217 Added an option to make PCI bus transactions rounded to a multiple of a
218 cache line size for better alignment.
220 Only available with Mellanox OFED >= 3.2.
222 * **Added mlx5 TX VLAN insertion support.**
224 Added support for TX VLAN insertion.
226 Only available with Mellanox OFED >= 3.2.
228 * **Changed szedata2 driver type from vdev to pdev.**
230 Previously szedata2 device had to be added by ``--vdev`` option.
231 Now szedata2 PMD recognizes the device automatically during EAL
234 * **Added szedata2 functions for setting link up/down.**
236 * **Added szedata2 promiscuous and allmulticast modes.**
238 * **Added af_packet dynamic removal function.**
240 An af_packet device can now be detached using the API, like other PMD devices.
242 * **Increased number of next hops for LPM IPv4 to 2^24.**
244 The ``next_hop`` field has been extended from 8 bits to 24 bits for IPv4.
246 * **Added support of SNOW 3G (UEA2 and UIA2) for Intel Quick Assist devices.**
248 Enabled support for the SNOW 3G wireless algorithm for Intel Quick Assist devices.
249 Support for cipher-only and hash-only is also provided
250 along with algorithm-chaining operations.
252 * **Added SNOW3G SW PMD.**
254 A new Crypto PMD has been added, which provides SNOW 3G UEA2 ciphering
255 and SNOW3G UIA2 hashing.
257 * **Added AES GCM PMD.**
259 Added new Crypto PMD to support AES-GCM authenticated encryption and
260 authenticated decryption in software.
262 * **Added NULL Crypto PMD**
264 Added new Crypto PMD to support null crypto operations in software.
266 * **Improved IP Pipeline Application.**
268 The following features have been added to ip_pipeline application;
270 * Added CPU utilization measurement and idle cycle rate computation.
271 * Added link identification support through existing port-mask option or by
272 specifying PCI device in every LINK section in the configuration file.
273 * Added load balancing support in passthrough pipeline.
275 * **Added IPsec security gateway example.**
277 Added a new application implementing an IPsec Security Gateway.
286 * **ethdev: Fixed overflow for 100Gbps.**
288 100Gbps in Mbps (100000) was exceeding the 16-bit max value of ``link_speed``
291 * **ethdev: Fixed byte order consistency between fdir flow and mask.**
293 Fixed issue in ethdev library where the structure for setting
294 fdir's mask and flow entry was not consistent in byte ordering.
296 * **cxgbe: Fixed crash due to incorrect size allocated for RSS table.**
298 Fixed a segfault that occurs when accessing part of port 0's RSS
299 table that gets overwritten by subsequent port 1's part of the RSS
300 table due to incorrect size allocated for each entry in the table.
302 * **cxgbe: Fixed setting wrong device MTU.**
304 Fixed an incorrect device MTU being set due to the Ethernet header and
305 CRC lengths being added twice.
307 * **ixgbe: Fixed zeroed VF mac address.**
309 Resolved an issue where the VF MAC address is zeroed out in cases where the VF
310 driver is loaded while the PF interface is down.
311 The solution is to only set it when we get an ACK from the PF.
313 * **ixgbe: Fixed setting flow director flag twice.**
315 Resolved an issue where packets were being dropped when switching to perfect
318 * **ixgbe: Set MDIO speed after MAC reset.**
320 The MDIO clock speed must be reconfigured after the MAC reset. The MDIO clock
321 speed becomes invalid, therefore the driver reads invalid PHY register values.
322 The driver now set the MDIO clock speed prior to initializing PHY ops and
323 again after the MAC reset.
325 * **ixgbe: Fixed maximum number of available TX queues.**
327 In IXGBE, the maximum number of TX queues varies depending on the NIC operating
328 mode. This was not being updated in the device information, providing
329 an incorrect number in some cases.
331 * **i40e: Generated MAC address for each VFs.**
333 It generates a MAC address for each VFs during PF host initialization,
334 and keeps the VF MAC address the same among different VF launch.
336 * **i40e: Fixed failure of reading/writing RX control registers.**
338 Fixed i40e issue of failing to read/write rx control registers when
339 under stress with traffic, which might result in application launch
342 * **i40e: Enabled vector driver by default.**
344 Previously, vector driver was disabled by default as it couldn't fill packet type
345 info for l3fwd to work well. Now there is an option for l3fwd to analyze
346 the packet type so the vector driver is enabled by default.
348 * **i40e: Fixed link info of VF.**
350 Previously, the VF's link speed stayed at 10GbE and status always was up.
351 It did not change even when the physical link's status changed.
352 Now this issue is fixed to make VF's link info consistent with physical link.
354 * **mlx5: Fixed possible crash during initialization.**
356 A crash could occur when failing to allocate private device context.
358 * **mlx5: Added port type check.**
360 Added port type check to prevent port initialization on non-Ethernet link layers and
363 * **mlx5: Applied VLAN filtering to broadcast and IPv6 multicast flows.**
365 Prevented reception of multicast frames outside of configured VLANs.
367 * **mlx5: Fixed RX checksum offload in non L3/L4 packets.**
369 Fixed report of bad checksum for packets of unknown type.
371 * **aesni_mb: Fixed wrong return value when creating a device.**
373 The ``cryptodev_aesni_mb_init()`` function was returning the device id of the device created,
374 instead of 0 (on success) that ``rte_eal_vdev_init()`` expects.
375 This made it impossible to create more than one aesni_mb device
376 from the command line.
378 * **qat: Fixed AES GCM decryption.**
380 Allowed AES GCM on the cryptodev API, but in some cases gave invalid results
381 due to incorrect IV setting.
387 * **hash: Fixed CRC32c hash computation for non multiple of 4 bytes sizes.**
389 Fix crc32c hash functions to return a valid crc32c value for data lengths
390 not a multiple of 4 bytes.
392 * **hash: Fixed hash library to support multi-process mode.**
394 Fix hash library to support multi-process mode, using a jump table,
395 instead of storing a function pointer to the key compare function.
396 Multi-process mode only works with the built-in compare functions,
397 however a custom compare function (not in the jump table) can only
398 be used in single-process mode.
400 * **hash: Fixed return value when allocating an existing hash table.**
402 Changed the ``rte_hash*_create()`` functions to return ``NULL`` and set
403 ``rte_errno`` to ``EEXIST`` when the object name already exists. This is
404 the behavior described in the API documentation in the header file.
405 The previous behavior was to return a pointer to the existing object in
406 that case, preventing the caller from knowing if the object had to be freed
409 * **lpm: Fixed return value when allocating an existing object.**
411 Changed the ``rte_lpm*_create()`` functions to return ``NULL`` and set
412 ``rte_errno`` to ``EEXIST`` when the object name already exists. This is
413 the behavior described in the API documentation in the header file.
414 The previous behavior was to return a pointer to the existing object in
415 that case, preventing the caller from knowing if the object had to be freed
418 * **librte_port: Fixed segmentation fault for ring and ethdev writer nodrop.**
420 Fixed core dump issue on txq and swq when dropless is set to yes.
426 * **l3fwd-power: Fixed memory leak for non-IP packet.**
428 Fixed issue in l3fwd-power where, on receiving packets of types
429 other than IPv4 or IPv6, the mbuf was not released, and caused
432 * **l3fwd: Fixed using packet type blindly.**
434 l3fwd makes use of packet type information without querying if devices or PMDs
435 really set it. For those devices that don't set ptypes, add an option to parse it.
437 * **examples/vhost: Fixed frequent mbuf allocation failure.**
439 The vhost-switch often fails to allocate mbuf when dequeue from vring because it
440 wrongly calculates the number of mbufs needed.
446 * The ethdev statistics counter ``imissed`` is considered to be independent of ``ierrors``.
447 All drivers are now counting the missed packets only once, i.e. drivers will
448 not increment ierrors anymore for missed packets.
450 * The ethdev structure ``rte_eth_dev_info`` was changed to support device
453 * The ethdev structures ``rte_eth_link`` and ``rte_eth_conf`` were changed to
454 support the new link API.
456 * The functions ``rte_eth_dev_udp_tunnel_add`` and ``rte_eth_dev_udp_tunnel_delete``
457 have been renamed into ``rte_eth_dev_udp_tunnel_port_add`` and
458 ``rte_eth_dev_udp_tunnel_port_delete``.
460 * The ``outer_mac`` and ``inner_mac`` fields in structure
461 ``rte_eth_tunnel_filter_conf`` are changed from pointer to struct in order
462 to keep code's readability.
464 * The fields in ethdev structure ``rte_eth_fdir_masks`` were changed
467 * A parameter ``vlan_type`` has been added to the function
468 ``rte_eth_dev_set_vlan_ether_type``.
470 * The af_packet device init function is no longer public. The device should be attached
473 * The LPM ``next_hop`` field is extended from 8 bits to 24 bits for IPv4
474 while keeping ABI compatibility.
476 * A new ``rte_lpm_config`` structure is used so the LPM library will allocate
477 exactly the amount of memory which is necessary to hold application’s rules.
478 The previous ABI is kept for compatibility.
480 * The prototype for the pipeline input port, output port and table action
481 handlers are updated: the pipeline parameter is added,
482 the packets mask parameter has been either removed or made input-only.
488 * The RETA entry size in ``rte_eth_rss_reta_entry64`` has been increased
489 from 8-bit to 16-bit.
491 * The ethdev flow director structure ``rte_eth_fdir_flow`` structure was
492 changed. New fields were added to extend flow director's input set.
494 * The cmdline buffer size has been increase from 256 to 512.
