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