35 * **Added a new driver for ThunderX nicvf devices.**
37 Added the new thunderx net driver for ThunderX nicvf devices. See the
38 "Network Interface Controller Drivers" document for more details on this new
41 * **Added mailbox interrupt support for ixgbe and igb VFs.**
43 When the physical NIC link comes up or down, the PF driver will send a
44 mailbox message to notify each VF. To handle this link up/down event,
45 support have been added for a mailbox interrupt to receive the message and
46 allow the application to register a callback for it.
48 * **Updated the ixgbe base driver.**
50 The ixgbe base driver was updated with changes including the
53 * Added sgmii link for X550.

64 * **Updated the enic driver.**
66 The enic driver was updated with changes including the following:
68 * Optimized the Tx function.
69 * Added Scattered Rx capability.
70 * Improved packet type identification.
71 * Added MTU update in non Scattered Rx mode and enabled MTU of up to 9208
72 with UCS Software release 2.2 on 1300 series VICs.
74 * **Updated the mlx5 driver.**
76 The mlx5 driver was updated with changes including the following:
78 * Data path was refactored to bypass Verbs to improve RX and TX performance.
79 * Removed compilation parameters for inline send, ``MLX5_MAX_INLINE``, and
80 added command line parameter instead, ``txq_inline``.
81 * Improved TX scatter gather support:
82 Removed compilation parameter ``MLX5_PMD_SGE_WR_N``.
83 Scatter-gather elements is set to the maximum value the NIC supports.
84 Removed linearization logic, this decreases the memory consumption of the PMD.
85 * Improved jumbo frames support, by dynamically setting RX scatter gather elements
86 according to the MTU and mbuf size,
87 no need for compilation parameter ``MLX5_PMD_SGE_WR_N``
89 * **Added support for virtio on IBM POWER8.**
91 The ioports are mapped in memory when using Linux UIO.
93 * **Added support for Virtio in containers.**
95 Add a new virtual device, named virtio_user, to support virtio for containers.
99 * Control queue and multi-queue are not supported yet.
100 * Doesn't work with ``--huge-unlink``.
101 * Doesn't work with ``--no-huge``.
102 * Doesn't work when there are more than ``VHOST_MEMORY_MAX_NREGIONS(8)`` hugepages.
103 * Root privilege is required for sorting hugepages by physical address.
104 * Can only be used with the vhost user backend.
106 * **Added vhost-user client mode.**
108 DPDK vhost-user now supports client mode as well as server mode. Client mode
109 is enabled when the ``RTE_VHOST_USER_CLIENT`` flag is set while calling
110 ``rte_vhost_driver_register``.
112 When DPDK vhost-user restarts from an normal or abnormal exit (such as a
113 crash), the client mode allows DPDK to establish the connection again. Note
114 that QEMU version v2.7 or above is required for this feature.
116 DPDK vhost-user will also try to reconnect by default when:
118 * The first connect fails (for example when QEMU is not started yet).
119 * The connection is broken (for example when QEMU restarts).
121 It can be turned off by setting the ``RTE_VHOST_USER_NO_RECONNECT`` flag.
123 * **Added NSH packet recognition in i40e.**
125 * **Added AES-CTR support to AESNI MB PMD.**
127 Now AESNI MB PMD supports 128/192/256-bit counter mode AES encryption and
130 * **Added AES counter mode support for Intel QuickAssist devices.**
132 Enabled support for the AES CTR algorithm for Intel QuickAssist devices.
133 Provided support for algorithm-chaining operations.
135 * **Added KASUMI SW PMD.**
137 A new Crypto PMD has been added, which provides KASUMI F8 (UEA1) ciphering
138 and KASUMI F9 (UIA1) hashing.
140 * **Added multi-writer support for RTE Hash with Intel TSX.**
142 The following features/modifications have been added to rte_hash library:
144 * Enabled application developers to use an extra flag for ``rte_hash``
145 creation to specify default behavior (multi-thread safe/unsafe) with the
146 ``rte_hash_add_key`` function.
147 * Changed the Cuckoo Hash Search algorithm to breadth first search for
148 multi-writer routines and split Cuckoo Hash Search and Move operations in
149 order to reduce transactional code region and improve TSX performance.
150 * Added a hash multi-writer test case to the test app.
152 * **Improved IP Pipeline Application.**
154 The following features have been added to the ip_pipeline application:
156 * Configure the MAC address in the routing pipeline and automatic route
157 updates with change in link state.
158 * Enable RSS per network interface through the configuration file.
159 * Streamline the CLI code.
161 * **Added keepalive enhancements.**
163 Added support for reporting of core states other than "dead" to
164 monitoring applications, enabling the support of broader liveness
165 reporting to external processes.
167 * **Added packet capture framework.**
169 * A new library ``librte_pdump`` is added to provide a packet capture API.
170 * A new ``app/pdump`` tool is added to demonstrate capture packets in DPDK.
173 * **Added floating VEB support for i40e PF driver.**
175 A "floating VEB" is a special Virtual Ethernet Bridge (VEB) which does not
176 have an upload port, but instead is used for switching traffic between
177 virtual functions (VFs) on a port.
179 For information on this feature, please see the "I40E Poll Mode Driver"
180 section of the "Network Interface Controller Drivers" document.
182 * **Added support for live migration of a VM with SRIOV VF.**
184 Live migration of a VM with Virtio and VF PMD's using the bonding PMD.
193 * **igb_uio: Fixed possible mmap failure for Linux >= 4.5.**
195 The mmapping of the iomem range of the PCI device fails for kernels that
196 enabled the ``CONFIG_IO_STRICT_DEVMEM`` option. The error seen by the
197 user is as similar to the following::
199 EAL: pci_map_resource():
201 cannot mmap(39, 0x7f1c51800000, 0x100000, 0x0):
202 Invalid argument (0xffffffffffffffff)
204 The ``CONFIG_IO_STRICT_DEVMEM`` kernel option was introduced in Linux v4.5.
206 The issues was resolve by updating ``igb_uio`` to stop reserving PCI memory
207 resources. From the kernel point of view the iomem region looks like idle
208 and mmap works again. This matches the ``uio_pci_generic`` usage.
214 * **i40e: Fixed vlan stripping from inner header.**
216 Previously, for tunnel packets, such as VXLAN/NVGRE, the vlan
217 tags of the inner header will be stripped without putting vlan
219 Now this issue is fixed by disabling vlan stripping from inner header.
221 * **i40e: Fixed the type issue of a single VLAN type.**
223 Currently, if a single VLAN header is added in a packet, it's treated
224 as inner VLAN. But generally, a single VLAN header is treated as the
226 This issue is fixed by changing corresponding register for single VLAN.
228 * **enic: Fixed several issues when stopping then restarting ports and queues.**
230 Fixed several crashes related to stopping then restarting ports and queues.
231 Fixed possible crash when re-configuring the number of Rx queue descriptors.
233 * **enic: Fixed Rx data mis-alignment if mbuf data offset modified.**
235 Fixed possible Rx corruption when mbufs were returned to a pool with data
236 offset other than RTE_PKTMBUF_HEADROOM.
238 * **enic: Fixed Tx IP/UDP/TCP checksum offload and VLAN insertion.**
240 * **enic: Fixed Rx error and missed counters.**
246 * **mbuf: Fixed refcnt update when detaching.**
248 Fix the ``rte_pktmbuf_detach()`` function to decrement the direct mbuf's
249 reference counter. The previous behavior was not to affect the reference
250 counter. This lead to a memory leak of the direct mbuf.
256 * The following counters are removed from the ``rte_eth_stats`` structure:
268 * The extended statistics are fetched by ids with ``rte_eth_xstats_get``
269 after a lookup by name ``rte_eth_xstats_get_names``.
271 * The function ``rte_eth_dev_info_get`` fill the new fields ``nb_rx_queues``
272 and ``nb_tx_queues`` in the structure ``rte_eth_dev_info``.
274 * The vhost function ``rte_vring_available_entries`` is renamed to
275 ``rte_vhost_avail_entries``.
277 * All existing vhost APIs and callbacks with ``virtio_net`` struct pointer
278 as the parameter have been changed due to the ABI refactoring described
279 below. It is replaced by ``int vid``.
281 * The function ``rte_vhost_enqueue_burst`` no longer supports concurrent enqueuing
282 packets to the same queue.
284 * The function ``rte_eth_dev_set_mtu`` adds a new return value ``-EBUSY``, which
285 indicates the operation is forbidden because the port is running.
287 * The script ``dpdk_nic_bind.py`` is renamed to ``dpdk-devbind.py``.
288 And the script ``setup.sh`` is renamed to ``dpdk-setup.sh``.
294 * The ``rte_port_source_params`` structure has new fields to support PCAP files.
295 It was already in release 16.04 with ``RTE_NEXT_ABI`` flag.
297 * The ``rte_eth_dev_info`` structure has new fields ``nb_rx_queues`` and ``nb_tx_queues``
298 to support the number of queues configured by software.
300 * A Vhost ABI refactoring has been made: the ``virtio_net`` structure is no
301 longer exported directly to the application. Instead, a handle, ``vid``, has
302 been used to represent this structure internally.
