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
* 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
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
~~~~~
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.
+
Removed Items
-------------
* KNI vhost support removed.
+* dpdk_qat sample application removed.
