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 * **Removed the mempool cache memory if caching is not being used.**

68 "Network Interface Controller Drivers" document for more details on this new
71 * **Added mailbox interrupt support for ixgbe and igb VFs.**
73 When the physical NIC link comes up or down, the PF driver will send a
74 mailbox message to notify each VF. To handle this link up/down event,
75 support have been added for a mailbox interrupt to receive the message and
76 allow the application to register a callback for it.
78 * **Updated the ixgbe base driver.**
80 The ixgbe base driver was updated with changes including the
83 * Added sgmii link for X550.

98 * Optimized the Tx function.
99 * Added Scattered Rx capability.
100 * Improved packet type identification.
101 * Added MTU update in non Scattered Rx mode and enabled MTU of up to 9208
102 with UCS Software release 2.2 on 1300 series VICs.
104 * **Updated the mlx5 driver.**
106 The mlx5 driver was updated with changes including the following:
108 * Data path was refactored to bypass Verbs to improve RX and TX performance.
109 * Removed compilation parameters for inline send, ``MLX5_MAX_INLINE``, and
110 added command line parameter instead, ``txq_inline``.
111 * Improved TX scatter gather support:
112 Removed compilation parameter ``MLX5_PMD_SGE_WR_N``.
113 Scatter-gather elements is set to the maximum value the NIC supports.
114 Removed linearization logic, this decreases the memory consumption of the PMD.
115 * Improved jumbo frames support, by dynamically setting RX scatter gather elements
116 according to the MTU and mbuf size,
117 no need for compilation parameter ``MLX5_PMD_SGE_WR_N``
119 * **Added support for virtio on IBM POWER8.**
121 The ioports are mapped in memory when using Linux UIO.
123 * **Added support for Virtio in containers.**
125 Add a new virtual device, named virtio_user, to support virtio for containers.
129 * Control queue and multi-queue are not supported yet.
130 * Doesn't work with ``--huge-unlink``.
131 * Doesn't work with ``--no-huge``.
132 * Doesn't work when there are more than ``VHOST_MEMORY_MAX_NREGIONS(8)`` hugepages.
133 * Root privilege is required for sorting hugepages by physical address.
134 * Can only be used with the vhost user backend.
136 * **Added vhost-user client mode.**
138 DPDK vhost-user now supports client mode as well as server mode. Client mode
139 is enabled when the ``RTE_VHOST_USER_CLIENT`` flag is set while calling
140 ``rte_vhost_driver_register``.
142 When DPDK vhost-user restarts from an normal or abnormal exit (such as a
143 crash), the client mode allows DPDK to establish the connection again. Note
144 that QEMU version v2.7 or above is required for this feature.
146 DPDK vhost-user will also try to reconnect by default when:
148 * The first connect fails (for example when QEMU is not started yet).
149 * The connection is broken (for example when QEMU restarts).
151 It can be turned off by setting the ``RTE_VHOST_USER_NO_RECONNECT`` flag.
153 * **Added NSH packet recognition in i40e.**
155 * **Added AES-CTR support to AESNI MB PMD.**
157 Now AESNI MB PMD supports 128/192/256-bit counter mode AES encryption and
160 * **Added AES counter mode support for Intel QuickAssist devices.**
162 Enabled support for the AES CTR algorithm for Intel QuickAssist devices.
163 Provided support for algorithm-chaining operations.
165 * **Added KASUMI SW PMD.**
167 A new Crypto PMD has been added, which provides KASUMI F8 (UEA1) ciphering
168 and KASUMI F9 (UIA1) hashing.
170 * **Added multi-writer support for RTE Hash with Intel TSX.**
172 The following features/modifications have been added to rte_hash library:
174 * Enabled application developers to use an extra flag for ``rte_hash``
175 creation to specify default behavior (multi-thread safe/unsafe) with the
176 ``rte_hash_add_key`` function.
177 * Changed the Cuckoo Hash Search algorithm to breadth first search for
178 multi-writer routines and split Cuckoo Hash Search and Move operations in
179 order to reduce transactional code region and improve TSX performance.
180 * Added a hash multi-writer test case to the test app.
182 * **Improved IP Pipeline Application.**
184 The following features have been added to the ip_pipeline application:
186 * Configure the MAC address in the routing pipeline and automatic route
187 updates with change in link state.
188 * Enable RSS per network interface through the configuration file.
189 * Streamline the CLI code.
191 * **Added keepalive enhancements.**
193 Added support for reporting of core states other than "dead" to
194 monitoring applications, enabling the support of broader liveness
195 reporting to external processes.
197 * **Added packet capture framework.**
199 * A new library ``librte_pdump`` is added to provide a packet capture API.
200 * A new ``app/pdump`` tool is added to demonstrate capture packets in DPDK.
203 * **Added floating VEB support for i40e PF driver.**
205 A "floating VEB" is a special Virtual Ethernet Bridge (VEB) which does not
206 have an upload port, but instead is used for switching traffic between
207 virtual functions (VFs) on a port.
209 For information on this feature, please see the "I40E Poll Mode Driver"
210 section of the "Network Interface Controller Drivers" document.
212 * **Added support for live migration of a VM with SRIOV VF.**
214 Live migration of a VM with Virtio and VF PMD's using the bonding PMD.
220 .. This section should contain bug fixes added to the relevant sections. Sample format:
222 * **code/section Fixed issue in the past tense with a full stop.**
224 Add a short 1-2 sentence description of the resolved issue in the past tense.
225 The title should contain the code/lib section like a commit message.
226 Add the entries in alphabetic order in the relevant sections below.
232 * **igb_uio: Fixed possible mmap failure for Linux >= 4.5.**
234 The mmaping of the iomem range of the PCI device fails for kernels that
235 enabled the ``CONFIG_IO_STRICT_DEVMEM`` option. The error seen by the
236 user is as similar to the following::
238 EAL: pci_map_resource():
240 cannot mmap(39, 0x7f1c51800000, 0x100000, 0x0):
241 Invalid argument (0xffffffffffffffff)
243 The ``CONFIG_IO_STRICT_DEVMEM`` kernel option was introduced in Linux v4.5.
245 The issues was resolve by updating ``igb_uio`` to stop reserving PCI memory
246 resources. From the kernel point of view the iomem region looks like idle
247 and mmap works again. This matches the ``uio_pci_generic`` usage.
253 * **i40e: Fixed vlan stripping from inner header.**
255 Previously, for tunnel packets, such as VXLAN/NVGRE, the vlan
256 tags of the inner header will be stripped without putting vlan
258 Now this issue is fixed by disabling vlan stripping from inner header.
260 * **i40e: Fixed the type issue of a single VLAN type.**
262 Currently, if a single VLAN header is added in a packet, it's treated
263 as inner VLAN. But generally, a single VLAN header is treated as the
265 This issue is fixed by changing corresponding register for single VLAN.
267 * **enic: Fixed several issues when stopping then restarting ports and queues.**
269 Fixed several crashes related to stopping then restarting ports and queues.
270 Fixed possible crash when re-configuring the number of Rx queue descriptors.
272 * **enic: Fixed Rx data mis-alignment if mbuf data offset modified.**
274 Fixed possible Rx corruption when mbufs were returned to a pool with data
275 offset other than RTE_PKTMBUF_HEADROOM.
277 * **enic: Fixed Tx IP/UDP/TCP checksum offload and VLAN insertion.**
279 * **enic: Fixed Rx error and missed counters.**
285 * **mbuf: Fixed refcnt update when detaching.**
287 Fix the ``rte_pktmbuf_detach()`` function to decrement the direct mbuf's
288 reference counter. The previous behavior was not to affect the reference
289 counter. This lead to a memory leak of the direct mbuf.
303 .. This section should contain new known issues in this release. Sample format:
305 * **Add title in present tense with full stop.**
307 Add a short 1-2 sentence description of the known issue in the present
308 tense. Add information on any known workarounds.
314 .. This section should contain API changes. Sample format:
316 * Add a short 1-2 sentence description of the API change. Use fixed width
317 quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
319 * The following counters are removed from the ``rte_eth_stats`` structure:
331 * The extended statistics are fetched by ids with ``rte_eth_xstats_get``
332 after a lookup by name ``rte_eth_xstats_get_names``.
334 * The function ``rte_eth_dev_info_get`` fill the new fields ``nb_rx_queues``
335 and ``nb_tx_queues`` in the structure ``rte_eth_dev_info``.
337 * The vhost function ``rte_vring_available_entries`` is renamed to
338 ``rte_vhost_avail_entries``.
340 * All existing vhost APIs and callbacks with ``virtio_net`` struct pointer
341 as the parameter have been changed due to the ABI refactoring described
342 below. It is replaced by ``int vid``.
344 * The function ``rte_vhost_enqueue_burst`` no longer supports concurrent enqueuing
345 packets to the same queue.
347 * The function ``rte_eth_dev_set_mtu`` adds a new return value ``-EBUSY``, which
348 indicates the operation is forbidden because the port is running.
350 * The script ``dpdk_nic_bind.py`` is renamed to ``dpdk-devbind.py``.
351 And the script ``setup.sh`` is renamed to ``dpdk-setup.sh``.
357 .. * Add a short 1-2 sentence description of the ABI change that was announced in
358 the previous releases and made in this release. Use fixed width quotes for
359 ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
361 * The ``rte_port_source_params`` structure has new fields to support PCAP files.
362 It was already in release 16.04 with ``RTE_NEXT_ABI`` flag.
364 * The ``rte_eth_dev_info`` structure has new fields ``nb_rx_queues`` and ``nb_tx_queues``
365 to support the number of queues configured by software.
367 * A Vhost ABI refactoring has been made: the ``virtio_net`` structure is no
368 longer exported directly to the application. Instead, a handle, ``vid``, has
369 been used to represent this structure internally.
