+
+New Features
+------------
+
+.. This section should contain new features added in this release. Sample format:
+
+ * **Add a title in the past tense with a full stop.**
+
+ Add a short 1-2 sentence description in the past tense. The description
+ should be enough to allow someone scanning the release notes to understand
+ the new feature.
+
+ If the feature adds a lot of sub-features you can use a bullet list like this.
+
+ * Added feature foo to do something.
+ * Enhanced feature bar to do something else.
+
+ Refer to the previous release notes for examples.
+
+* **Removed mempool cache if not needed.**
+
+ The size of the mempool structure is reduced if the per-lcore cache is disabled.
+
+* **Added mempool external cache for non-EAL thread.**
+
+ Added new functions to create, free or flush a user-owned mempool
+ cache for non-EAL threads. Previously, cache was always disabled
+ on these threads.
+
+* **Changed the memory allocation in mempool library.**
+
+ * Added ability to allocate a large mempool in virtually fragmented memory.
+ * Added new APIs to populate a mempool with memory.
+ * Added an API to free a mempool.
+ * Modified the API of rte_mempool_obj_iter() function.
+ * Dropped specific Xen Dom0 code.
+ * Dropped specific anonymous mempool code in testpmd.
+
+* **Added new driver for Broadcom NetXtreme-C devices.**
+
+ Added the new bnxt driver for Broadcom NetXtreme-C devices. See the
+ "Network Interface Controller Drivers" document for more details on this
+ new driver.
+
+* **Added new driver for ThunderX nicvf device.**
+
+* **Added mailbox interrupt support for ixgbe and igb VFs.**
+
+ When the physical NIC link comes down or up, the PF driver will send a
+ mailbox message to notify each VF. To handle this link up/down event,
+ add mailbox interrupts support to receive the message and allow the app to
+ register a callback for it.
+
+* **Updated the ixgbe base driver.**
+
+ The ixgbe base driver was updated with changes including the
+ following:
+
+ * Added sgmii link for X550.
+ * Added mac link setup for X550a SFP and SFP+.
+ * Added KR support for X550em_a.
+ * Added new phy definitions for M88E1500.
+ * Added support for the VLVF to be bypassed when adding/removing a VFTA entry.
+ * Added X550a flow control auto negotiation support.
+
+* **Updated the i40e base driver.**
+
+ Updated the i40e base driver, which includes support for new devices IDs.
+
+* **Supported virtio on IBM POWER8.**
+
+ The ioports are mapped in memory when using Linux UIO.
+
+* **Virtio support for containers.**
+
+ Add a new virtual device, named virtio-user, to support virtio for containers.
+
+ Known limitations:
+
+ * Control queue and multi-queue are not supported yet.
+ * Cannot work with --huge-unlink.
+ * Cannot work with --no-huge.
+ * Cannot work when there are more than VHOST_MEMORY_MAX_NREGIONS(8) hugepages.
+ * Root privilege is a must for sorting hugepages by physical address.
+ * Can only be used with vhost user backend.
+
+* **Added vhost-user client mode.**
+
+ DPDK vhost-user could be the server as well as the client. It supports
+ server mode only before, now it also supports client mode. Client mode
+ is enabled when ``RTE_VHOST_USER_CLIENT`` flag is set while calling
+ ``rte_vhost_driver_register``.
+
+ When DPDK vhost-user restarts from normal or abnormal quit (say crash),
+ the client mode would allow DPDK to establish the connect again. Note
+ that a brand new QEMU version (v2.7 or above) is needed, otherwise, the
+ reconnect won't work.
+
+ DPDK vhost-user will also try to reconnect by default when
+
+ * the first connect fails (when QEMU is not started yet)
+ * the connection is broken (when QEMU restarts)
+
+ It can be turned off if flag ``RTE_VHOST_USER_NO_RECONNECT`` is set.
+
+* **Added NSH packet recognition in i40e.**
+
+* **Added AES-CTR support to AESNI MB PMD.**
+
+ Now AESNI MB PMD supports 128/192/256-bit counter mode AES encryption and
+ decryption.
+
+* **Added support of AES counter mode for Intel QuickAssist devices.**
+
+ Enabled support for the AES CTR algorithm for Intel QuickAssist devices.
+ Provided support for algorithm-chaining operations.
+
+* **Added KASUMI SW PMD.**
+
+ A new Crypto PMD has been added, which provides KASUMI F8 (UEA1) ciphering
+ 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 rte_hash_add_key
+ function.
+ * Changed Cuckoo search algorithm to breadth first search for multi-writer
+ routine and split Cuckoo Search and Move operations in order to reduce
+ transactional code region and improve TSX performance.
+ * Added a hash multi-writer test case for test app.
+
+* **Improved IP Pipeline Application.**
+
+ The following features have been added to ip_pipeline application:
+
+ * Configure the MAC address in the routing pipeline and automatic routes
+ updates with change in link state.
+ * Enable RSS per network interface through the configuration file.
+ * Streamline the CLI code.
+
+* **Added keepalive enhancements.**
+
+ Adds 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 packet capture API.
+ * A new ``app/pdump`` tool is added to 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.
+
+
+Resolved Issues
+---------------
+
+.. This section should contain bug fixes added to the relevant sections. Sample format:
+
+ * **code/section Fixed issue in the past tense with a full stop.**
+
+ Add a short 1-2 sentence description of the resolved issue in the past tense.
+ The title should contain the code/lib section like a commit message.
+ Add the entries in alphabetic order in the relevant sections below.
+
+
+EAL
+~~~
+
+
+Drivers
+~~~~~~~
+
+* **i40e: Fixed vlan stripping from inner header.**
+
+ Previously, for tunnel packets, such as VXLAN/NVGRE, the vlan
+ tags of the inner header will be stripped without putting vlan
+ 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.
+
+
+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.
+

+
+Known Issues
+------------
+
+.. This section should contain new known issues in this release. Sample format:
+
+ * **Add title in present tense with full stop.**
+
+ Add a short 1-2 sentence description of the known issue in the present
+ tense. Add information on any known workarounds.
+
+
+API Changes
+-----------
+
+.. This section should contain API changes. Sample format:
+
+ * 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 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 mentioned
+ below: it's 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.
+
+
+ABI Changes
+-----------
+
+.. * Add a short 1-2 sentence description of the ABI change that was announced in
+ 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.
+ 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 number of queues configured by software.
+
+* vhost ABI refactoring has been made: ``virtio_net`` structure is never
+ exported to application any more. Instead, a handle, ``vid``, has been
+ used to represent this structure internally.
+
