25 .. This section should contain new features added in this release. Sample format:
27 * **Add a title in the past tense with a full stop.**
29 Add a short 1-2 sentence description in the past tense. The description
30 should be enough to allow someone scanning the release notes to understand
33 If the feature adds a lot of sub-features you can use a bullet list like this.
35 * Added feature foo to do something.
36 * Enhanced feature bar to do something else.
38 Refer to the previous release notes for examples.
40 This section is a comment. Make sure to start the actual text at the margin.
43 * **Added software parser for packet type.**
45 * Added a new function ``rte_pktmbuf_read()`` to read the packet data from an
46 mbuf chain, linearizing if required.
47 * Added a new function ``rte_net_get_ptype()`` to parse an Ethernet packet
48 in an mbuf chain and retrieve its packet type from software.
49 * Added new functions ``rte_get_ptype_*()`` to dump a packet type as a string.
51 * **Improved offloads support in mbuf.**
53 * Added a new function ``rte_raw_cksum_mbuf()`` to process the checksum of
54 data embedded in an mbuf chain.
55 * Added new Rx checksum flags in mbufs to describe more states: unknown,
56 good, bad, or not present (useful for virtual drivers). This modification
57 was done for IP and L4.
58 * Added a new Rx LRO mbuf flag, used when packets are coalesced. This
59 flag indicates that the segment size of original packets is known.
61 * **Added vhost-user dequeue zero copy support.**
63 The copy in the dequeue path is avoided in order to improve the performance.
64 In the VM2VM case, the boost is quite impressive. The bigger the packet size,
65 the bigger performance boost you may get. However, for the VM2NIC case, there
66 are some limitations, so the boost is not as impressive as the VM2VM case.
67 It may even drop quite a bit for small packets.
69 For that reason, this feature is disabled by default. It can be enabled when
70 the ``RTE_VHOST_USER_DEQUEUE_ZERO_COPY`` flag is set. Check the VHost section
71 of the Programming Guide for more information.
73 * **Added vhost-user indirect descriptors support.**
75 If the indirect descriptor feature is enabled, each packet sent by the guest
76 will take exactly one slot in the enqueue virtqueue. Without this feature, as in
77 the current version, even 64 bytes packets take two slots with Virtio PMD on guest
80 The main impact is better performance for 0% packet loss use-cases, as it
81 behaves as if the virtqueue size was enlarged, so more packets can be buffered
82 in the case of system perturbations. On the downside, small performance degradations
83 were measured when running micro-benchmarks.
85 * **Added vhost PMD xstats.**
87 Added extended statistics to vhost PMD from a per port perspective.
89 * **Supported offloads with virtio.**
91 Added support for the following offloads in virtio:
97 * **Added virtio NEON support for ARM.**
99 Added NEON support for ARM based virtio.
101 * **Updated the ixgbe base driver.**
103 Updated the ixgbe base driver, including the following changes:
105 * Added X550em_a 10G PHY support.
106 * Added support for flow control auto negotiation for X550em_a 1G PHY.
107 * Added X550em_a FW ALEF support.
108 * Increased mailbox version to ``ixgbe_mbox_api_13``.
109 * Added two MAC operations for Hyper-V support.
111 * **Added APIs for VF management to the ixgbe PMD.**
113 Eight new APIs have been added to the ixgbe PMD for VF management from the PF.
114 The declarations for the API's can be found in ``rte_pmd_ixgbe.h``.
116 * **Updated the enic driver.**
118 * Added update to use interrupt for link status checking instead of polling.
119 * Added more flow director modes on UCS Blade with firmware version >= 2.0(13e).
120 * Added full support for MTU update.
121 * Added support for the ``rte_eth_rx_queue_count`` function.
123 * **Updated the mlx5 driver.**
125 * Added support for RSS hash results.
126 * Added several performance improvements.
127 * Added several bug fixes.
129 * **Updated the QAT PMD.**
131 The QAT PMD was updated with additional support for:
133 * MD5_HMAC algorithm.
134 * SHA224-HMAC algorithm.
135 * SHA384-HMAC algorithm.
137 * KASUMI (F8 and F9) algorithm.
143 * **Added openssl PMD.**
145 A new crypto PMD has been added, which provides several ciphering and hashing algorithms.
146 All cryptography operations use the Openssl library crypto API.
148 * **Updated the IPsec example.**
150 Updated the IPsec example with the following support:
152 * Configuration file support.
153 * AES CBC IV generation with cipher forward function.
156 * **Added support for new gcc -march option.**
158 The GCC 4.9 ``-march`` option supports the Intel processor code names.
159 The config option ``RTE_MACHINE`` can be used to pass code names to the compiler via the ``-march`` flag.
165 .. This section should contain bug fixes added to the relevant sections. Sample format:
167 * **code/section Fixed issue in the past tense with a full stop.**
169 Add a short 1-2 sentence description of the resolved issue in the past tense.
170 The title should contain the code/lib section like a commit message.
171 Add the entries in alphabetic order in the relevant sections below.
173 This section is a comment. Make sure to start the actual text at the margin.
179 * **enic: Fixed several flow director issues.**
181 * **enic: Fixed inadvertent setting of L4 checksum ptype on ICMP packets.**
183 * **enic: Fixed high driver overhead when servicing Rx queues beyond the first.**
190 .. This section should contain new known issues in this release. Sample format:
192 * **Add title in present tense with full stop.**
194 Add a short 1-2 sentence description of the known issue in the present
195 tense. Add information on any known workarounds.
197 This section is a comment. Make sure to start the actual text at the margin.
199 * **L3fwd-power app does not work properly when Rx vector is enabled.**
201 The L3fwd-power app doesn't work properly with some drivers in vector mode
202 since the queue monitoring works differently between scalar and vector modes
203 leading to incorrect frequency scaling. In addition, L3fwd-power application
204 requires the mbuf to have correct packet type set but in some drivers the
205 vector mode must be disabled for this.
207 Therefore, in order to use L3fwd-power, vector mode should be disabled
210 * **Digest address must be supplied for crypto auth operation on QAT PMD.**
212 The cryptodev API specifies that if the rte_crypto_sym_op.digest.data field,
213 and by inference the digest.phys_addr field which points to the same location,
214 is not set for an auth operation the driver is to understand that the digest
215 result is located immediately following the region over which the digest is
216 computed. The QAT PMD doesn't correctly handle this case and reads and writes
217 to an incorrect location.
219 Callers can workaround this by always supplying the digest virtual and
220 physical address fields in the rte_crypto_sym_op for an auth operation.
226 .. This section should contain API changes. Sample format:
228 * Add a short 1-2 sentence description of the API change. Use fixed width
229 quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
231 This section is a comment. Make sure to start the actual text at the margin.
233 * The driver naming convention has been changed to make them more
234 consistent. It especially impacts ``--vdev`` arguments. For example
235 ``eth_pcap`` becomes ``net_pcap`` and ``cryptodev_aesni_mb_pmd`` becomes
238 For backward compatibility an alias feature has been enabled to support the
241 * The log history has been removed.
243 * The ``rte_ivshmem`` feature (including library and EAL code) has been removed
244 in 16.11 because it had some design issues which were not planned to be fixed.
246 * The ``file_name`` data type of ``struct rte_port_source_params`` and
247 ``struct rte_port_sink_params`` is changed from ``char *`` to ``const char *``.
249 * **Improved device/driver hierarchy and generalized hotplugging.**
251 The device and driver relationship has been restructured by introducing generic
252 classes. This paves the way for having PCI, VDEV and other device types as
253 instantiated objects rather than classes in themselves. Hotplugging has also
254 been generalized into EAL so that Ethernet or crypto devices can use the
255 common infrastructure.
257 * Removed ``pmd_type`` as a way of segregation of devices.
258 * Moved ``numa_node`` and ``devargs`` into ``rte_driver`` from
259 ``rte_pci_driver``. These can now be used by any instantiated object of
261 * Added ``rte_device`` class and all PCI and VDEV devices inherit from it
262 * Renamed devinit/devuninit handlers to probe/remove to make it more
263 semantically correct with respect to the device <=> driver relationship.
264 * Moved hotplugging support to EAL. Hereafter, PCI and vdev can use the
265 APIs ``rte_eal_dev_attach`` and ``rte_eal_dev_detach``.
266 * Renamed helpers and support macros to make them more synonymous
267 with their device types
268 (e.g. ``PMD_REGISTER_DRIVER`` => ``RTE_PMD_REGISTER_PCI``).
269 * Device naming functions have been generalized from ethdev and cryptodev
270 to EAL. ``rte_eal_pci_device_name`` has been introduced for obtaining
271 unique device name from PCI Domain-BDF description.
272 * Virtual device registration APIs have been added: ``rte_eal_vdrv_register``
273 and ``rte_eal_vdrv_unregister``.
279 .. This section should contain ABI changes. Sample format:
281 * Add a short 1-2 sentence description of the ABI change that was announced in
282 the previous releases and made in this release. Use fixed width quotes for
283 ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
