+ =========================================================
+
+* **Reworked memory subsystem.**
+
+ Memory subsystem has been reworked to support new functionality.
+
+ On Linux, support for reserving/unreserving hugepage memory at runtime has been
+ added, so applications no longer need to pre-reserve memory at startup. Due to
+ reorganized internal workings of memory subsystem, any memory allocated
+ through ``rte_malloc()`` or ``rte_memzone_reserve()`` is no longer guaranteed
+ to be IOVA-contiguous.
+
+ This functionality has introduced the following changes:
+
+ * ``rte_eal_get_physmem_layout()`` was removed.
+ * A new flag for memzone reservation (``RTE_MEMZONE_IOVA_CONTIG``) was added
+ to ensure reserved memory will be IOVA-contiguous, for use with device
+ drivers and other cases requiring such memory.
+ * New callbacks for memory allocation/deallocation events, allowing users (or
+ drivers) to be notified of new memory being allocated or deallocated
+ * New callbacks for validating memory allocations above a specified limit,
+ allowing user to permit or deny memory allocations.
+ * A new command-line switch ``--legacy-mem`` to enable EAL behavior similar to
+ how older versions of DPDK worked (memory segments that are IOVA-contiguous,
+ but hugepages are reserved at startup only, and can never be released).
+ * A new command-line switch ``--single-file-segments`` to put all memory
+ segments within a segment list in a single file.
+ * A set of convenience function calls to look up and iterate over allocated
+ memory segments.
+ * ``-m`` and ``--socket-mem`` command-line arguments now carry an additional
+ meaning and mark pre-reserved hugepages as "unfree-able", thereby acting as
+ a mechanism guaranteeing minimum availability of hugepage memory to the
+ application.
+
+ Reserving/unreserving memory at runtime is not currently supported on FreeBSD.
+
+* **Added bucket mempool driver.**
+
+ Added a bucket mempool driver which provides a way to allocate contiguous
+ block of objects.
+ The number of objects in the block depends on how many objects fit in the
+ ``RTE_DRIVER_MEMPOOL_BUCKET_SIZE_KB`` memory chunk which is a build time option.
+ The number may be obtained using ``rte_mempool_ops_get_info()`` API.
+ Contiguous blocks may be allocated using ``rte_mempool_get_contig_blocks()`` API.
+
+* **Added support for port representors.**
+
+ Added DPDK port representors (also known as "VF representors" in the specific
+ context of VFs), which are to DPDK what the Ethernet switch device driver
+ model (**switchdev**) is to Linux, and which can be thought as a software
+ "patch panel" front-end for applications. DPDK port representors are
+ implemented as additional virtual Ethernet device (**ethdev**) instances,
+ spawned on an as-needed basis through configuration parameters passed to the
+ driver of the underlying device using devargs.
+
+* **Added support for VXLAN and NVGRE tunnel endpoint.**
+
+ New actions types have been added to support encapsulation and decapsulation
+ operations for a tunnel endpoint. The new action types are
+ ``RTE_FLOW_ACTION_TYPE_[VXLAN/NVGRE]_ENCAP``, ``RTE_FLOW_ACTION_TYPE_[VXLAN/NVGRE]_DECAP``,
+ ``RTE_FLOW_ACTION_TYPE_JUMP``. A new item type ``RTE_FLOW_ACTION_TYPE_MARK`` has been
+ added to match a flow against a previously marked flow. A shared counter has also been
+ introduced to the flow API to count a group of flows.
+
+* **Added PMD-recommended Tx and Rx parameters.**
+
+ Applications can now query drivers for device-tuned values of
+ ring sizes, burst sizes, and number of queues.
+
+* **Added RSS hash and key update to CXGBE PMD.**
+
+ Added support for updating the RSS hash and key to the CXGBE PMD.
+
+* **Added CXGBE VF PMD.**
+
+ CXGBE VF Poll Mode Driver has been added to run DPDK over Chelsio
+ T5/T6 NIC VF instances.
+
+* **Updated mlx5 driver.**
+
+ Updated the mlx5 driver including the following changes:
+
+ * Introduced Multi-packet Rx to enable 100Gb/sec with 64B frames.
+ * Support for being run by non-root users given a reduced set of capabilities
+ ``CAP_NET_ADMIN``, ``CAP_NET_RAW`` and ``CAP_IPC_LOCK``.
+ * Support for TSO and checksum for generic UDP and IP tunnels.
+ * Support for inner checksum and RSS for GRE, VXLAN-GPE, MPLSoGRE
+ and MPLSoUDP tunnels.
+ * Accommodate the new memory hotplug model.
+ * Support for non virtually contiguous mempools.
+ * Support for MAC adding along with allmulti and promiscuous modes from VF.
+ * Support for Mellanox BlueField SoC device.
+ * Support for PMD defaults for queue number and depth to improve the out
+ of the box performance.
+
+* **Updated mlx4 driver.**
+
+ Updated the mlx4 driver including the following changes:
+
+ * Support for to being run by non-root users given a reduced set of capabilities
+ ``CAP_NET_ADMIN``, ``CAP_NET_RAW`` and ``CAP_IPC_LOCK``.
+ * Supported CRC strip toggling.
+ * Accommodate the new memory hotplug model.
+ * Support non virtually contiguous mempools.
+ * Dropped support for Mellanox OFED 4.2.
+
+* **Updated Solarflare network PMD.**
+
+ Updated the sfc_efx driver including the following changes:
+
+ * Added support for Solarflare XtremeScale X2xxx family adapters.
+ * Added support for NVGRE, VXLAN and GENEVE filters in flow API.
+ * Added support for DROP action in flow API.
+ * Added support for equal stride super-buffer Rx mode (X2xxx only).
+ * Added support for MARK and FLAG actions in flow API (X2xxx only).
+
+* **Added Ethernet poll mode driver for AMD XGBE devices.**
+
+ Added the new ``axgbe`` ethernet poll mode driver for AMD XGBE devices.
+ See the :doc:`../nics/axgbe` nic driver guide for more details on this
+ new driver.
+
+* **Updated szedata2 PMD.**
+
+ Added support for new NFB-200G2QL card.
+ A new API was introduced in the libsze2 library which the szedata2 PMD depends
+ on, thus the new version of the library was needed.
+ New versions of the packages are available and the minimum required version
+ is 4.4.1.
+
+* **Added support for Broadcom NetXtreme-S (BCM58800) family of controllers (aka Stingray).**
+
+ Added support for the Broadcom NetXtreme-S (BCM58800) family of controllers
+ (aka Stingray). The BCM58800 devices feature a NetXtreme E-Series advanced
+ network controller, a high-performance ARM CPU block, PCI Express (PCIe)
+ Gen3 interfaces, key accelerators for compute offload and a high-speed
+ memory subsystem including L3 cache and DDR4 interfaces, all interconnected
+ by a coherent Network-on-chip (NOC) fabric.
+
+ The ARM CPU subsystem features eight ARMv8 Cortex-A72 CPUs at 3.0 GHz,
+ arranged in a multi-cluster configuration.
+
+* **Added vDPA in vhost-user lib.**
+
+ Added support for selective datapath in the vhost-user lib. vDPA stands for vhost
+ Data Path Acceleration. It supports virtio ring compatible devices to serve
+ the virtio driver directly to enable datapath acceleration.
+
+* **Added IFCVF vDPA driver.**
+
+ Added IFCVF vDPA driver to support Intel FPGA 100G VF devices. IFCVF works
+ as a HW vhost data path accelerator, it supports live migration and is
+ compatible with virtio 0.95 and 1.0. This driver registers the ifcvf vDPA driver
+ to vhost lib, when virtio connects. With the help of the registered vDPA
+ driver the assigned VF gets configured to Rx/Tx directly to VM's virtio
+ vrings.
+
+* **Added support for vhost dequeue interrupt mode.**
+
+ Added support for vhost dequeue interrupt mode to release CPUs to others
+ when there is no data to transmit. Applications can register an epoll event
+ file descriptor to associate Rx queues with interrupt vectors.
+
+* **Added support for virtio-user server mode.**
+
+ In a container environment if the vhost-user backend restarts, there's no way
+ for it to reconnect to virtio-user. To address this, support for server mode
+ has been added. In this mode the socket file is created by virtio-user, which the
+ backend connects to. This means that if the backend restarts, it can reconnect
+ to virtio-user and continue communications.
+
+* **Added crypto workload support to vhost library.**
+
+ New APIs have been introduced in the vhost library to enable virtio crypto support
+ including session creation/deletion handling and translating virtio-crypto
+ requests into DPDK crypto operations. A sample application has also been introduced.
+
+* **Added virtio crypto PMD.**
+
+ Added a new Poll Mode Driver for virtio crypto devices, which provides
+ AES-CBC ciphering and AES-CBC with HMAC-SHA1 algorithm-chaining. See the
+ :doc:`../cryptodevs/virtio` crypto driver guide for more details on
+ this new driver.
+
+* **Added AMD CCP Crypto PMD.**
+
+ Added the new ``ccp`` crypto driver for AMD CCP devices. See the
+ :doc:`../cryptodevs/ccp` crypto driver guide for more details on
+ this new driver.
+
+* **Updated AESNI MB PMD.**
+
+ The AESNI MB PMD has been updated with additional support for:
+
+ * AES-CMAC (128-bit key).
+
+* **Added the Compressdev Library, a generic compression service library.**
+
+ Added the Compressdev library which provides an API for offload of compression and
+ decompression operations to hardware or software accelerator devices.
+
+* **Added a new compression poll mode driver using Intels ISA-L.**
+
+ Added the new ``ISA-L`` compression driver, for compression and decompression
+ operations in software. See the :doc:`../compressdevs/isal` compression driver
+ guide for details on this new driver.
+
+* **Added the Event Timer Adapter Library.**
+
+ The Event Timer Adapter Library extends the event-based model by introducing
+ APIs that allow applications to arm/cancel event timers that generate
+ timer expiry events. This new type of event is scheduled by an event device
+ along with existing types of events.
+
+* **Added OcteonTx TIM Driver (Event timer adapter).**
+
+ The OcteonTx Timer block enables software to schedule events for a future
+ time, it is exposed to an application via the Event timer adapter library.
+
+ See the :doc:`../eventdevs/octeontx` guide for more details
+
+* **Added Event Crypto Adapter Library.**
+
+ Added the Event Crypto Adapter Library. This library extends the
+ event-based model by introducing APIs that allow applications to
+ enqueue/dequeue crypto operations to/from cryptodev as events scheduled
+ by an event device.
+
+* **Added Ifpga Bus, a generic Intel FPGA Bus library.**
+
+ Added the Ifpga Bus library which provides support for integrating any Intel
+ FPGA device with the DPDK framework. It provides Intel FPGA Partial Bit
+ Stream AFU (Accelerated Function Unit) scan and drivers probe.
+
+* **Added IFPGA (Intel FPGA) Rawdev Driver.**
+
+ Added a new Rawdev driver called IFPGA (Intel FPGA) Rawdev Driver, which cooperates
+ with OPAE (Open Programmable Acceleration Engine) shared code to provide common FPGA
+ management ops for FPGA operation.
+
+ See the :doc:`../rawdevs/ifpga_rawdev` programmer's guide for more details.
+
+* **Added DPAA2 QDMA Driver (in rawdev).**
+
+ The DPAA2 QDMA is an implementation of the rawdev API, that provide a means
+ of initiating a DMA transaction from CPU. The initiated DMA is performed
+ without the CPU being involved in the actual DMA transaction.
+
+ See the :doc:`../rawdevs/dpaa2_qdma` guide for more details.
+
+* **Added DPAA2 Command Interface Driver (in rawdev).**
+
+ The DPAA2 CMDIF is an implementation of the rawdev API, that provides
+ communication between the GPP and NXP's QorIQ based AIOP Block (Firmware).
+ Advanced IO Processor i.e. AIOP are clusters of programmable RISC engines
+ optimized for flexible networking and I/O operations. The communication
+ between GPP and AIOP is achieved via using DPCI devices exposed by MC for
+ GPP <--> AIOP interaction.
+
+ See the :doc:`../rawdevs/dpaa2_cmdif` guide for more details.
+
+* **Added device event monitor framework.**
+
+ Added a general device event monitor framework to EAL, for device dynamic
+ management to facilitate device hotplug awareness and associated
+ actions. The list of new APIs is:
+
+ * ``rte_dev_event_monitor_start`` and ``rte_dev_event_monitor_stop`` for
+ the event monitor enabling and disabling.
+ * ``rte_dev_event_callback_register`` and ``rte_dev_event_callback_unregister``
+ for registering and un-registering user callbacks.
+
+ Linux uevent is supported as a backend of this device event notification framework.
+
+* **Added support for procinfo and pdump on eth vdev.**
+
+ For ethernet virtual devices (like TAP, PCAP, etc.), with this feature, we can get
+ stats/xstats on shared memory from a secondary process, and also pdump packets on
+ those virtual devices.
+
+* **Enhancements to the Packet Framework Library.**
+
+ Design and development of new API functions for Packet Framework library that
+ implement a common set of actions such as traffic metering, packet
+ encapsulation, network address translation, TTL update, etc., for pipeline
+ table and input ports to speed up application development. The API functions
+ includes creating action profiles, registering actions to the profiles,
+ instantiating action profiles for pipeline table and input ports, etc.
+
+* **Added the BPF Library.**
+
+ The BPF Library provides the ability to load and execute
+ Enhanced Berkeley Packet Filters (eBPF) within user-space DPDK applications.
+ It also introduces a basic framework to load/unload BPF-based filters
+ on Eth devices (right now only via SW RX/TX callbacks).
+ It also adds a dependency on libelf.
+
+
+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.
+
+ This section is a comment. Do not overwrite or remove it.
+ Also, make sure to start the actual text at the margin.
+ =========================================================
+
+* service cores: No longer marked as experimental.
+
+ The service cores functions are no longer marked as experimental, and have
+ become part of the normal DPDK API and ABI. Any future ABI changes will be
+ announced at least one release before the ABI change is made. There are no
+ ABI breaking changes planned.
+
+* eal: The ``rte_lcore_has_role()`` return value changed.
+
+ This function now returns true or false, respectively,
+ rather than 0 or < 0 for success or failure.
+ It makes use of the function more intuitive.
+
+* mempool: The capability flags and related functions have been removed.
+
+ Flags ``MEMPOOL_F_CAPA_PHYS_CONTIG`` and
+ ``MEMPOOL_F_CAPA_BLK_ALIGNED_OBJECTS`` were used by octeontx mempool
+ driver to customize generic mempool library behavior.
+ Now the new driver callbacks ``calc_mem_size`` and ``populate`` may be
+ used to achieve it without specific knowledge in the generic code.
+
+* mempool: The following xmem functions have been deprecated:
+
+ - ``rte_mempool_xmem_create``
+ - ``rte_mempool_xmem_size``
+ - ``rte_mempool_xmem_usage``
+ - ``rte_mempool_populate_iova_tab``
+
+* mbuf: The control mbuf API has been removed in v18.05. The impacted
+ functions and macros are:
+
+ - ``rte_ctrlmbuf_init()``
+ - ``rte_ctrlmbuf_alloc()``
+ - ``rte_ctrlmbuf_free()``
+ - ``rte_ctrlmbuf_data()``
+ - ``rte_ctrlmbuf_len()``
+ - ``rte_is_ctrlmbuf()``
+ - ``CTRL_MBUF_FLAG``
+
+ The packet mbuf API should be used as a replacement.
+
+* meter: API updated to accommodate configuration profiles.
+
+ The meter API has been changed to support meter configuration profiles. The
+ configuration profile represents the set of configuration parameters
+ for a given meter object, such as the rates and sizes for the token
+ buckets. These configuration parameters were previously part of the meter
+ object internal data structure. The separation of the configuration
+ parameters from the meter object data structure results in reducing its
+ memory footprint which helps in better cache utilization when a large number
+ of meter objects are used.
+
+* ethdev: The function ``rte_eth_dev_count()``, often mis-used to iterate
+ over ports, is deprecated and replaced by ``rte_eth_dev_count_avail()``.
+ There is also a new function ``rte_eth_dev_count_total()`` to get the
+ total number of allocated ports, available or not.
+ The hotplug-proof applications should use ``RTE_ETH_FOREACH_DEV`` or
+ ``RTE_ETH_FOREACH_DEV_OWNED_BY`` as port iterators.
+
+* ethdev: In struct ``struct rte_eth_dev_info``, field ``rte_pci_device *pci_dev``
+ has been replaced with field ``struct rte_device *device``.
+
+* ethdev: Changes to the semantics of ``rte_eth_dev_configure()`` parameters.
+
+ If both the ``nb_rx_q`` and ``nb_tx_q`` parameters are zero,
+ ``rte_eth_dev_configure()`` will now use PMD-recommended queue sizes, or if
+ recommendations are not provided by the PMD the function will use ethdev
+ fall-back values. Previously setting both of the parameters to zero would
+ have resulted in ``-EINVAL`` being returned.
+
+* ethdev: Changes to the semantics of ``rte_eth_rx_queue_setup()`` parameters.
+
+ If the ``nb_rx_desc`` parameter is zero, ``rte_eth_rx_queue_setup`` will
+ now use the PMD-recommended Rx ring size, or in the case where the PMD
+ does not provide a recommendation, will use an ethdev-provided
+ fall-back value. Previously, setting ``nb_rx_desc`` to zero would have
+ resulted in an error.
+
+* ethdev: Changes to the semantics of ``rte_eth_tx_queue_setup()`` parameters.
+
+ If the ``nb_tx_desc`` parameter is zero, ``rte_eth_tx_queue_setup`` will
+ now use the PMD-recommended Tx ring size, or in the case where the PMD
+ does not provide a recommendation, will use an ethdev-provided
+ fall-back value. Previously, setting ``nb_tx_desc`` to zero would have
+ resulted in an error.
+
+* ethdev: Several changes were made to the flow API.
+
+ * The unused DUP action was removed.
+ * Actions semantics in flow rules: list order now matters ("first
+ to last" instead of "all simultaneously"), repeated actions are now
+ all performed, and they do not individually have (non-)terminating
+ properties anymore.
+ * Flow rules are now always terminating unless a ``PASSTHRU`` action is
+ present.
+ * C99-style flexible arrays were replaced with standard pointers in RSS
+ action and in RAW pattern item structures due to compatibility issues.
+ * The RSS action was modified to not rely on external
+ ``struct rte_eth_rss_conf`` anymore to instead expose its own and more
+ appropriately named configuration fields directly
+ (``rss_conf->rss_key`` => ``key``,
+ ``rss_conf->rss_key_len`` => ``key_len``,
+ ``rss_conf->rss_hf`` => ``types``,
+ ``num`` => ``queue_num``), and the addition of missing RSS parameters
+ (``func`` for RSS hash function to apply and ``level`` for the
+ encapsulation level).
+ * The VLAN pattern item (``struct rte_flow_item_vlan``) was modified to
+ include inner EtherType instead of outer TPID. Its default mask was also
+ modified to cover the VID part (lower 12 bits) of TCI only.
+ * A new transfer attribute was added to ``struct rte_flow_attr`` in order
+ to clarify the behavior of some pattern items.
+ * PF and VF pattern items are now only accepted by PMDs that implement
+ them (bnxt and i40e) when the transfer attribute is also present, for
+ consistency.
+ * Pattern item PORT was renamed PHY_PORT to avoid confusion with DPDK port
+ IDs.
+ * An action counterpart to the PHY_PORT pattern item was added in order to
+ redirect matching traffic to a specific physical port.
+ * PORT_ID pattern item and actions were added to match and target DPDK
+ port IDs at a higher level than PHY_PORT.
+ * ``RTE_FLOW_ACTION_TYPE_[VXLAN/NVGRE]_ENCAP`` action items were added to support
+ tunnel encapsulation operation for VXLAN and NVGRE type tunnel endpoint.
+ * ``RTE_FLOW_ACTION_TYPE_[VXLAN/NVGRE]_DECAP`` action items were added to support
+ tunnel decapsulation operation for VXLAN and NVGRE type tunnel endpoint.
+ * ``RTE_FLOW_ACTION_TYPE_JUMP`` action item was added to support a matched flow
+ to be redirected to the specific group.
+ * ``RTE_FLOW_ACTION_TYPE_MARK`` item type has been added to match a flow against
+ a previously marked flow.
+
+* ethdev: Change flow APIs regarding count action:
+
+ * ``rte_flow_create()`` API count action now requires the ``struct rte_flow_action_count``.
+ * ``rte_flow_query()`` API parameter changed from action type to action structure.
+
+* ethdev: Changes to offload API
+
+ A pure per-port offloading isn't requested to be repeated in [rt]x_conf->offloads to
+ ``rte_eth_[rt]x_queue_setup()``. Now any offloading enabled in ``rte_eth_dev_configure()``
+ can't be disabled by ``rte_eth_[rt]x_queue_setup()``. Any new added offloading which has
+ not been enabled in ``rte_eth_dev_configure()`` and is requested to be enabled in
+ ``rte_eth_[rt]x_queue_setup()`` must be per-queue type, or otherwise trigger an error log.
+
+* ethdev: Runtime queue setup
+
+ ``rte_eth_rx_queue_setup`` and ``rte_eth_tx_queue_setup`` can be called after
+ ``rte_eth_dev_start`` if the device supports runtime queue setup. The device driver can
+ expose this capability through ``rte_eth_dev_info_get``. A Rx or Tx queue
+ set up at runtime need to be started explicitly by ``rte_eth_dev_rx_queue_start``
+ or ``rte_eth_dev_tx_queue_start``.
+
+
+ABI Changes
+-----------
+
+.. This section should contain ABI changes. Sample format:
+
+ * 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.
+
+ This section is a comment. Do not overwrite or remove it.
+ Also, make sure to start the actual text at the margin.
+ =========================================================
+
+* ring: The alignment constraints on the ring structure has been relaxed
+ to one cache line instead of two, and an empty cache line padding is
+ added between the producer and consumer structures. The size of the
+ structure and the offset of the fields remains the same on platforms
+ with 64B cache line, but changes on other platforms.
+
+* mempool: Some ops have changed.
+
+ A new callback ``calc_mem_size`` has been added to ``rte_mempool_ops``
+ to allow customization of the required memory size calculation.
+ A new callback ``populate`` has been added to ``rte_mempool_ops``
+ to allow customized object population.
+ Callback ``get_capabilities`` has been removed from ``rte_mempool_ops``
+ since its features are covered by ``calc_mem_size`` and ``populate``
+ callbacks.
+ Callback ``register_memory_area`` has been removed from ``rte_mempool_ops``
+ since the new callback ``populate`` may be used instead of it.
+
+* ethdev: Additional fields in rte_eth_dev_info.
+
+ The ``rte_eth_dev_info`` structure has had two extra entries appended to the
+ end of it: ``default_rxportconf`` and ``default_txportconf``. Each of these
+ in turn are ``rte_eth_dev_portconf`` structures containing three fields of
+ type ``uint16_t``: ``burst_size``, ``ring_size``, and ``nb_queues``. These
+ are parameter values recommended for use by the PMD.
+
+* ethdev: ABI for all flow API functions was updated.
+
+ This includes functions ``rte_flow_copy``, ``rte_flow_create``,
+ ``rte_flow_destroy``, ``rte_flow_error_set``, ``rte_flow_flush``,
+ ``rte_flow_isolate``, ``rte_flow_query`` and ``rte_flow_validate``, due to
+ changes in error type definitions (``enum rte_flow_error_type``), removal
+ of the unused DUP action (``enum rte_flow_action_type``), modified
+ behavior for flow rule actions (see API changes), removal of C99 flexible
+ array from RAW pattern item (``struct rte_flow_item_raw``), complete
+ rework of the RSS action definition (``struct rte_flow_action_rss``),
+ sanity fix in the VLAN pattern item (``struct rte_flow_item_vlan``) and
+ new transfer attribute (``struct rte_flow_attr``).
+
+* bbdev: New parameter added to rte_bbdev_op_cap_turbo_dec.
+
+ A new parameter ``max_llr_modulus`` has been added to
+ ``rte_bbdev_op_cap_turbo_dec`` structure to specify maximal LLR (likelihood
+ ratio) absolute value.
+
+* bbdev: Queue Groups split into UL/DL Groups.
+
+ Queue Groups have been split into UL/DL Groups in the Turbo Software Driver.
+ They are independent for Decode/Encode. ``rte_bbdev_driver_info`` reflects
+ introduced changes.
+
+
+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.
+
+ This section is a comment. Do not overwrite or remove it.
+ Also, make sure to start the actual text at the margin.
+ =========================================================
+
+* **Secondary process launch is not reliable.**
+
+ Recent memory hotplug patches have made multiprocess startup less reliable
+ than it was in past releases. A number of workarounds are known to work depending
+ on the circumstances. As such it isn't recommended to use the secondary
+ process mechanism for critical systems. The underlying issues will be
+ addressed in upcoming releases.
+
+ The issue is explained in more detail, including potential workarounds,
+ in the Bugzilla entry referenced below.
+
+ Bugzilla entry: https://dpdk.org/tracker/show_bug.cgi?id=50
+
+* **pdump is not compatible with old applications.**
+
+ As we changed to use generic multi-process communication for pdump
+ negotiation instead of previous dedicated unix socket way, pdump
+ applications, including the dpdk-pdump example and any other applications
+ using ``librte_pdump``, will not work with older version DPDK primary
+ applications.
+
+* **rte_abort takes a long time on FreeBSD.**
+
+ DPDK processes now allocates a large area of virtual memory address space.
+ As a result ``rte_abort`` on FreeBSD now dumps the contents of the
+ whole reserved memory range, not just the used portion, to a core dump file.
+ Writing this large core file can take a significant amount of time, causing
+ processes to appear to hang on the system.
+
+ The work around for the issue is to set the system resource limits for core
+ dumps before running any tests, e.g. ``limit coredumpsize 0``. This will
+ effectively disable core dumps on FreeBSD. If they are not to be completely
+ disabled, a suitable limit, e.g. 1G might be specified instead of 0. This
+ needs to be run per-shell session, or before every test run. This change
+ can also be made persistent by adding ``kern.coredump=0`` to ``/etc/sysctl.conf``.

+
+* **ixgbe PMD crash on hotplug detach when no VF created.**
+
+ ixgbe PMD uninit path cause null pointer dereference because of port representor
+ cleanup when number of VF is zero.

+* **Bonding PMD may fail to accept new slave ports in certain conditions.**
+
+ In certain conditions when using testpmd,
+ bonding may fail to register new slave ports.

+
+* **Unexpected performance regression in Vhost library.**
+
+ Patches fixing CVE-2018-1059 were expected to introduce a small performance
+ drop. However, in some setups, bigger performance drops have been measured
+ when running micro-benchmarks.
