+ Scatter-gather elements is set to the maximum value the NIC supports.
+ Removed linearization logic, this decreases the memory consumption of the PMD.
+ * Improved jumbo frames support, by dynamically setting RX scatter gather elements
+ according to the MTU and mbuf size,
+ no need for compilation parameter ``MLX5_PMD_SGE_WR_N``
+
+* **Added support for virtio on IBM POWER8.**
+
+ The ioports are mapped in memory when using Linux UIO.

+
+ Known limitations:
+
+ * Control queue and multi-queue are not supported yet.
+ * Doesn't work with ``--huge-unlink``.
+ * Doesn't work with ``--no-huge``.
+ * Doesn't work when there are more than ``VHOST_MEMORY_MAX_NREGIONS(8)`` hugepages.
+ * Root privilege is required for sorting hugepages by physical address.
+ * Can only be used with the vhost user backend.
+
+* **Added vhost-user client mode.**
+
+ DPDK vhost-user now supports client mode as well as server mode. Client mode
+ is enabled when the ``RTE_VHOST_USER_CLIENT`` flag is set while calling
+ ``rte_vhost_driver_register``.
+
+ When DPDK vhost-user restarts from an normal or abnormal exit (such as a
+ crash), the client mode allows DPDK to establish the connection again. Note
+ that QEMU version v2.7 or above is required for this feature.
+
+ DPDK vhost-user will also try to reconnect by default when:
+
+ * The first connect fails (for example when QEMU is not started yet).
+ * The connection is broken (for example when QEMU restarts).
+
+ It can be turned off by setting the ``RTE_VHOST_USER_NO_RECONNECT`` flag.
+
+* **Added NSH packet recognition in i40e.**

+ and KASUMI F9 (UIA1) hashing.
+
+* **Added multi-writer support for RTE Hash with Intel TSX.**
+
+ The following features/modifications have been added to rte_hash library:
+
+ * Enabled application developers to use an extra flag for ``rte_hash``
+ creation to specify default behavior (multi-thread safe/unsafe) with the
+ ``rte_hash_add_key`` function.
+ * Changed the Cuckoo Hash Search algorithm to breadth first search for
+ multi-writer routines and split Cuckoo Hash Search and Move operations in
+ order to reduce transactional code region and improve TSX performance.
+ * Added a hash multi-writer test case to the test app.
+
+* **Improved IP Pipeline Application.**
+
+ The following features have been added to the ip_pipeline application:
+
+ * Configure the MAC address in the routing pipeline and automatic route
+ updates with change in link state.
+ * Enable RSS per network interface through the configuration file.
+ * Streamline the CLI code.
+
+* **Added keepalive enhancements.**
+
+ Added support for reporting of core states other than "dead" to
+ monitoring applications, enabling the support of broader liveness
+ reporting to external processes.
+
+* **Added packet capture framework.**
+
+ * A new library ``librte_pdump`` is added to provide a packet capture API.
+ * A new ``app/pdump`` tool is added to demonstrate capture packets in DPDK.
+
+
+* **Added floating VEB support for i40e PF driver.**
+
+ A "floating VEB" is a special Virtual Ethernet Bridge (VEB) which does not
+ have an upload port, but instead is used for switching traffic between
+ virtual functions (VFs) on a port.
+
+ For information on this feature, please see the "I40E Poll Mode Driver"
+ section of the "Network Interface Controller Drivers" document.
+
+* **Added support for live migration of a VM with SRIOV VF.**
+
+ Live migration of a VM with Virtio and VF PMD's using the bonding PMD.
Resolved Issues
EAL
~~~
+* **igb_uio: Fixed possible mmap failure for Linux >= 4.5.**
+
+ The mmaping of the iomem range of the PCI device fails for kernels that
+ enabled the ``CONFIG_IO_STRICT_DEVMEM`` option. The error seen by the
+ user is as similar to the following::
+
+ EAL: pci_map_resource():
+
+ cannot mmap(39, 0x7f1c51800000, 0x100000, 0x0):
+ Invalid argument (0xffffffffffffffff)
+
+ The ``CONFIG_IO_STRICT_DEVMEM`` kernel option was introduced in Linux v4.5.
+
+ The issues was resolve by updating ``igb_uio`` to stop reserving PCI memory
+ resources. From the kernel point of view the iomem region looks like idle
+ and mmap works again. This matches the ``uio_pci_generic`` usage.
+
Drivers
~~~~~~~
info to descriptor.
Now this issue is fixed by disabling vlan stripping from inner header.
+* **i40e: Fixed the type issue of a single VLAN type.**
+
+ Currently, if a single VLAN header is added in a packet, it's treated
+ as inner VLAN. But generally, a single VLAN header is treated as the
+ outer VLAN header.
+ This issue is fixed by changing corresponding register for single VLAN.
+
+* **enic: Fixed several issues when stopping then restarting ports and queues.**
+
+ Fixed several crashes related to stopping then restarting ports and queues.
+ Fixed possible crash when re-configuring the number of Rx queue descriptors.
+
+* **enic: Fixed Rx data mis-alignment if mbuf data offset modified.**
+
+ Fixed possible Rx corruption when mbufs were returned to a pool with data
+ offset other than RTE_PKTMBUF_HEADROOM.
+
+* **enic: Fixed Tx IP/UDP/TCP checksum offload and VLAN insertion.**
+
+* **enic: Fixed Rx error and missed counters.**
+
Libraries
~~~~~~~~~
* **mbuf: Fixed refcnt update when detaching.**
- Fix the ``rte_pktmbuf_detach()`` function to decrement the direct
- mbuf's reference counter. The previous behavior was not to affect
- the reference counter. It lead a memory leak of the direct mbuf.
+ Fix the ``rte_pktmbuf_detach()`` function to decrement the direct mbuf's
+ reference counter. The previous behavior was not to affect the reference
+ counter. This lead to a memory leak of the direct mbuf.
Examples
* Add a short 1-2 sentence description of the API change. Use fixed width
quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
-* The following counters are removed from ``rte_eth_stats`` structure:
- ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
- tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff.
+* The following counters are removed from the ``rte_eth_stats`` structure:
+
+ * ``ibadcrc``
+ * ``ibadlen``
+ * ``imcasts``
+ * ``fdirmatch``
+ * ``fdirmiss``
+ * ``tx_pause_xon``
+ * ``rx_pause_xon``
+ * ``tx_pause_xoff``
+ * ``rx_pause_xoff``
+
+* The extended statistics are fetched by ids with ``rte_eth_xstats_get``
+ after a lookup by name ``rte_eth_xstats_get_names``.
+
+* The function ``rte_eth_dev_info_get`` fill the new fields ``nb_rx_queues``
+ and ``nb_tx_queues`` in the structure ``rte_eth_dev_info``.
+
+* The vhost function ``rte_vring_available_entries`` is renamed to
+ ``rte_vhost_avail_entries``.
+
+* All existing vhost APIs and callbacks with ``virtio_net`` struct pointer
+ as the parameter have been changed due to the ABI refactoring described
+ below. It is replaced by ``int vid``.
+
+* The function ``rte_vhost_enqueue_burst`` no longer supports concurrent enqueuing
+ packets to the same queue.
+
+* The function ``rte_eth_dev_set_mtu`` adds a new return value ``-EBUSY``, which
+ indicates the operation is forbidden because the port is running.
+
+* The script ``dpdk_nic_bind.py`` is renamed to ``dpdk-devbind.py``.
+ And the script ``setup.sh`` is renamed to ``dpdk-setup.sh``.
ABI Changes
the previous releases and made in this release. Use fixed width quotes for
``rte_function_names`` or ``rte_struct_names``. Use the past tense.
-* The ``rte_port_source_params`` structure has new fields to support PCAP file.
+* The ``rte_port_source_params`` structure has new fields to support PCAP files.
It was already in release 16.04 with ``RTE_NEXT_ABI`` flag.
+* The ``rte_eth_dev_info`` structure has new fields ``nb_rx_queues`` and ``nb_tx_queues``
+ to support the number of queues configured by software.
+
+* A Vhost ABI refactoring has been made: the ``virtio_net`` structure is no
+ longer exported directly to the application. Instead, a handle, ``vid``, has
+ been used to represent this structure internally.
