22 .. This section should contain new features added in this release. Sample format:
24 * **Add a title in the past tense with a full stop.**
26 Add a short 1-2 sentence description in the past tense. The description
27 should be enough to allow someone scanning the release notes to understand
30 If the feature adds a lot of sub-features you can use a bullet list like this.
32 * Added feature foo to do something.
33 * Enhanced feature bar to do something else.
35 Refer to the previous release notes for examples.
37 * **Removed mempool cache if not needed.**
39 The size of the mempool structure is reduced if the per-lcore cache is disabled.
41 * **Changed the memory allocation in mempool library.**
43 * Added ability to allocate a large mempool in virtually fragmented memory.
44 * Added new APIs to populate a mempool with memory.
45 * Added an API to free a mempool.
46 * Modified the API of rte_mempool_obj_iter() function.
47 * Dropped specific Xen Dom0 code.
48 * Dropped specific anonymous mempool code in testpmd.
50 * **Updated the i40e base driver.**
52 Updated the i40e base driver, which includes support for new devices IDs.
54 * **Supported virtio on IBM POWER8.**
56 The ioports are mapped in memory when using Linux UIO.
58 * **Virtio support for containers.**
60 Add a new virtual device, named virtio-user, to support virtio for containers.
64 * Control queue and multi-queue are not supported yet.
65 * Cannot work with --huge-unlink.
66 * Cannot work with --no-huge.
67 * Cannot work when there are more than VHOST_MEMORY_MAX_NREGIONS(8) hugepages.
68 * Root privilege is a must for sorting hugepages by physical address.
69 * Can only be used with vhost user backend.
71 * **Added vhost-user client mode.**
73 DPDK vhost-user could be the server as well as the client. It supports
74 server mode only before, now it also supports client mode. Client mode
75 is enabled when ``RTE_VHOST_USER_CLIENT`` flag is set while calling
76 ``rte_vhost_driver_register``.
78 When DPDK vhost-user restarts from normal or abnormal quit (say crash),
79 the client mode would allow DPDK to establish the connect again. Note
80 that a brand new QEMU version (v2.7 or above) is needed, otherwise, the
83 DPDK vhost-user will also try to reconnect by default when
85 * the first connect fails (when QEMU is not started yet)
86 * the connection is broken (when QEMU restarts)
88 It can be turned off if flag ``RTE_VHOST_USER_NO_RECONNECT`` is set.
90 * **Added NSH packet recognition in i40e.**
92 * **Added AES-CTR support to AESNI MB PMD.**
94 Now AESNI MB PMD supports 128/192/256-bit counter mode AES encryption and
97 * **Added support of AES counter mode for Intel QuickAssist devices.**
99 Enabled support for the AES CTR algorithm for Intel QuickAssist devices.
100 Provided support for algorithm-chaining operations.
102 * **Added KASUMI SW PMD.**
104 A new Crypto PMD has been added, which provides KASUMI F8 (UEA1) ciphering
105 and KASUMI F9 (UIA1) hashing.
107 * **Added multi-writer support for RTE Hash with Intel TSX.**
109 The following features/modifications have been added to rte_hash library:
111 * Enabled application developers to use an extra flag for rte_hash creation
112 to specify default behavior (multi-thread safe/unsafe) with rte_hash_add_key
114 * Changed Cuckoo search algorithm to breadth first search for multi-writer
115 routine and split Cuckoo Search and Move operations in order to reduce
116 transactional code region and improve TSX performance.
117 * Added a hash multi-writer test case for test app.
119 * **Improved IP Pipeline Application.**
121 The following features have been added to ip_pipeline application:
123 * Configure the MAC address in the routing pipeline and automatic routes
124 updates with change in link state.
125 * Enable RSS per network interface through the configuration file.
126 * Streamline the CLI code.
128 * **Added keepalive enhancements.**
130 Adds support for reporting of core states other than dead to
131 monitoring applications, enabling the support of broader liveness
132 reporting to external processes.
134 * **Added packet capture framework.**
136 * A new library ``librte_pdump`` is added to provide packet capture API.
137 * A new ``app/pdump`` tool is added to capture packets in DPDK.
143 .. This section should contain bug fixes added to the relevant sections. Sample format:
145 * **code/section Fixed issue in the past tense with a full stop.**
147 Add a short 1-2 sentence description of the resolved issue in the past tense.
148 The title should contain the code/lib section like a commit message.
149 Add the entries in alphabetic order in the relevant sections below.
159 * **i40e: Fixed vlan stripping from inner header.**
161 Previously, for tunnel packets, such as VXLAN/NVGRE, the vlan
162 tags of the inner header will be stripped without putting vlan
164 Now this issue is fixed by disabling vlan stripping from inner header.
170 * **mbuf: Fixed refcnt update when detaching.**
172 Fix the ``rte_pktmbuf_detach()`` function to decrement the direct
173 mbuf's reference counter. The previous behavior was not to affect
174 the reference counter. It lead a memory leak of the direct mbuf.
188 .. This section should contain new known issues in this release. Sample format:
190 * **Add title in present tense with full stop.**
192 Add a short 1-2 sentence description of the known issue in the present
193 tense. Add information on any known workarounds.
199 .. This section should contain API changes. Sample format:
201 * Add a short 1-2 sentence description of the API change. Use fixed width
202 quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
204 * The following counters are removed from ``rte_eth_stats`` structure:
205 ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
206 tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff.
208 * The extended statistics are fetched by ids with ``rte_eth_xstats_get``
209 after a lookup by name ``rte_eth_xstats_get_names``.
211 * The function ``rte_eth_dev_info_get`` fill the new fields ``nb_rx_queues``
212 and ``nb_tx_queues`` in the structure ``rte_eth_dev_info``.
214 * The vhost function ``rte_vring_available_entries`` is renamed to
215 ``rte_vhost_avail_entries``.
217 * All existing vhost APIs and callbacks with ``virtio_net`` struct pointer
218 as the parameter have been changed due to the ABI refactoring mentioned
219 below: it's replaced by ``int vid``.
221 * The function ``rte_vhost_enqueue_burst`` no longer supports concurrent enqueuing
222 packets to the same queue.
224 * The function ``rte_eth_dev_set_mtu`` adds a new return value ``-EBUSY``, which
225 indicates the operation is forbidden because the port is running.
231 .. * Add a short 1-2 sentence description of the ABI change that was announced in
232 the previous releases and made in this release. Use fixed width quotes for
233 ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
235 * The ``rte_port_source_params`` structure has new fields to support PCAP file.
236 It was already in release 16.04 with ``RTE_NEXT_ABI`` flag.
238 * The ``rte_eth_dev_info`` structure has new fields ``nb_rx_queues`` and ``nb_tx_queues``
239 to support number of queues configured by software.
241 * vhost ABI refactoring has been made: ``virtio_net`` structure is never
242 exported to application any more. Instead, a handle, ``vid``, has been
243 used to represent this structure internally.
