=========================================================
+* **Reorganized the mbuf structure.**
+
+ * Align fields to facilitate the writing of ``data_off``, ``refcnt``, and
+ ``nb_segs`` in one operation.
+ * Use 2 bytes for port and number of segments.
+ * Move the sequence number in the second cache line.
+ * Add a timestamp field.
+ * Set default value for ``refcnt``, ``next`` and ``nb_segs`` at mbuf free.
+
+* **Added mbuf raw free API**
+
+ Moved ``rte_mbuf_raw_free()`` and ``rte_pktmbuf_prefree_seg()`` functions to
+ the public API.
+
* **Added free Tx mbuf on demand API.**
Added a new function ``rte_eth_tx_done_cleanup()`` which allows an application
to request the driver to release mbufs from their Tx ring that are no longer
in use, independent of whether or not the ``tx_rs_thresh`` has been crossed.
+* **Added device removal interrupt.**
+
+ Added a new ethdev event ``RTE_ETH_DEV_INTR_RMV`` to signify
+ the sudden removal of a device.
+ This event can be advertized by PCI drivers and enabled accordingly.
+
+* **Added EAL dynamic log framework.**
+
+ Added new APIs to dynamically register named log types, and control
+ the level of each type independently.
+
* **Added descriptor status ethdev API.**
Added a new API to get the status of a descriptor.
* Added dynamic device personalization processing to i40e FW.
-* **Added TSO support for tunneled and non-tunneled packets on mlx5 driver.**
+* **Added Cloud Filter for QinQ steering to i40e.**
+
+ * Added a QinQ cloud filter on the i40e PMD, for steering traffic to a VM
+ using both VLAN tags.
+ * QinQ is not supported in Vector Mode on the i40e PMD.
+ * Vector Mode must be disabled when using the QinQ Cloud Filter.
+
+* **Updated mlx5 PMD.**
- Added support for Hardware TSO for tunneled and non-tunneled packets.
- Tunneling protocols supported are GRE and VXLAN.
+ * Supported ether type in flow item.
+ * Extended IPv6 flow item with Vtc flow, Protocol and Hop limit.
+ * Supported flag flow action.
+ * Supported RSS action flow rule.
+ * Supported TSO for tunneled and non-tunneled packets.
+ * Supported hardware checksum offloads for tunneled packets.
+ * Supported user space Rx interrupt event.
+ * Enhanced multi-packet send function for ConnectX-5.
-* **Added support for Rx interrupts on mlx5 driver.**
+* **Updated mlx4 PMD.**
- Rx queues can be armed with an interrupt which will trigger on the
- next packet arrival.
+ * Supported basic flow items and actions.
+ * Supported device removal event.
* **Updated the sfc_efx driver.**
Added poll mode driver support for Cavium LiquidIO II server adapter VFs.
+* **Added Atomic Rules Arkville PMD.**
+
+ Added a new poll mode driver for the Arkville family of
+ devices from Atomic Rules. The net/ark PMD supports line-rate
+ agnostic, multi-queue data movement on Arkville core FPGA instances.
+
+* **Added support for NXP DPAA2 - FSLMC bus.**
+
+ Added the new bus "fslmc" driver for NXP DPAA2 devices. See the
+ "Network Interface Controller Drivers" document for more details on this new
+ driver.
+
+* **Added support for NXP DPAA2 Network PMD.**
+
+ Added the new "dpaa2" net driver for NXP DPAA2 devices. See the
+ "Network Interface Controller Drivers" document for more details on this new
+ driver.
+
* **Added support for the Wind River Systems AVP PMD.**
Added a new networking driver for the AVP device type. Theses devices are
* Rxq interrupt for virtio-user + vhost-kernel as the backend.
* LSC interrupt for virtio-user + vhost-user as the backend.
+* **Added event driven programming model library (rte_eventdev).**
+
+ This API introduces event driven programming model.
+
+ In a polling model, lcores poll ethdev ports and associated
+ rx queues directly to look for packet. In an event driven model,
+ by contrast, lcores call the scheduler that selects packets for
+ them based on programmer-specified criteria. Eventdev library
+ added support for event driven programming model, which offer
+ applications automatic multicore scaling, dynamic load balancing,
+ pipelining, packet ingress order maintenance and
+ synchronization services to simplify application packet processing.
+
+ By introducing event driven programming model, DPDK can support
+ both polling and event driven programming models for packet processing,
+ and applications are free to choose whatever model
+ (or combination of the two) that best suits their needs.
+
+* **Added Software Eventdev PMD.**
+
+ Added support for the software eventdev PMD. The software eventdev is a
+ software based scheduler device that implements the eventdev API. This
+ PMD allows an application to configure a pipeline using the eventdev
+ library, and run the scheduling workload on a CPU core.
+
+* **Added Cavium OCTEONTX Eventdev PMD.**
+
+ Added the new octeontx ssovf eventdev driver for OCTEONTX devices. See the
+ "Event Device Drivers" document for more details on this new driver.
+
+* **Added information metric library.**
+
+ A library that allows information metrics to be added and updated
+ by producers, typically other libraries, for later retrieval by
+ consumers such as applications. It is intended to provide a
+ reporting mechanism that is independent of other libraries such
+ as ethdev.
+
+* **Added bit-rate calculation library.**
+
+ A library that can be used to calculate device bit-rates. Calculated
+ bitrates are reported using the metrics library.
+
+* **Added latency stats library.**
+
+ A library that measures packet latency. The collected statistics are jitter
+ and latency. For latency the minimum, average, and maximum is measured.
+
+* **Added NXP DPAA2 SEC crypto PMD.**
+
+ A new "dpaa2_sec" hardware based crypto PMD for NXP DPAA2 devices has been
+ added. See the "Crypto Device Drivers" document for more details on this
+ driver.
+
+* **Updated the Cryptodev Scheduler PMD.**
+
+ * Added packet-size based distribution mode, which distributes the enqueued
+ crypto operations among two slaves, based on their data lengths.
+ * Added fail-over scheduling mode, which enqueues crypto operations to a
+ primary slave first. Then, any operation that cannot be enqueued is
+ enqueued to a secondary slave.
+ * Added mode specific option support, so each scheduleing mode can
+ now be configured individually by the new added API.
+
+* **Updated the QAT PMD.**
+
+ The QAT PMD has been updated with additional support for:
+
+ * AES DOCSIS BPI algorithm.
+ * DES DOCSIS BPI algorithm.
+ * ZUC EEA3/EIA3 algorithms.
+
+* **Updated the AESNI MB PMD.**
+
+ The AESNI MB PMD has been updated with additional support for:
+
+ * AES DOCSIS BPI algorithm.
+
+* **Updated the OpenSSL PMD.**
+
+ The OpenSSL PMD has been updated with additional support for:
+
+ * DES DOCSIS BPI algorithm.
+
Resolved Issues
---------------
Examples
~~~~~~~~
+* **l2fwd-keepalive: Fixed unclean shutdowns.**
+
+ Added clean shutdown to l2fwd-keepalive so that it can free up
+ stale resources used for inter-process communication.
+
Other
~~~~~
``rte_vhost_driver_start`` should be used, and no need to create a
thread to call it.
+ * The vhost public header file ``rte_virtio_net.h`` is renamed to
+ ``rte_vhost.h``
+
ABI Changes

=========================================================
+* **Reorganized the mbuf structure.**
+
+ The order and size of the fields in the ``mbuf`` structure changed,
+ as described in the `New Features`_ section.
+
+* The ``rte_cryptodev_info.sym`` structure has new field ``max_nb_sessions_per_qp``
+ to support drivers which may support limited number of sessions per queue_pair.
+
