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. + + +Examples +~~~~~~~~ + + +Other +~~~~~ + + +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. + + +Shared Library Versions +----------------------- + +..
