+ * Added support for setting the link to specific speed.
+
* **Updated Intel i40e driver.**
Updated i40e PMD with new features and improvements, including:
* Added LLDP support.
* Extended PHY access AQ cmd.
* Added support for reading LPI counters.
- * Added support for Energy Efficient Ethernet
+ * Added support for Energy Efficient Ethernet.
+ * Added support for API rte_eth_tx_done_cleanup.
+ * Added support for VF multiple queues interrupt.
+ * Added support for setting the link to specific speed.
* **Updated Mellanox mlx5 driver.**
* Added support for RSS using L3/L4 source/destination only.
* Added support for matching on GTP tunnel header item.
+ * Removed limitation of matching on tagged/untagged packets (when using DV flow engine).
+
+* **Add new vDPA PMD based on Mellanox devices**
+
+ Added a new Mellanox vDPA (``mlx5_vdpa``) PMD.
+ See the :doc:`../vdpadevs/mlx5` guide for more details on this driver.
+
+* **Added support for virtio-PMD notification data.**
+
+ Added support for virtio-PMD notification data so that the driver
+ passes extra data (besides identifying the virtqueue) in its device
+ notifications, expanding the notifications to include the avail index and
+ avail wrap counter (When split ring is used, the avail wrap counter is not
+ included in the notification data).
* **Updated testpmd application.**
* ECPM (Elliptic Curve Point Multiplication) is added to
asymmetric crypto library specifications.
+* **Added synchronous Crypto burst API.**
+
+ A new API is introduced in crypto library to handle synchronous cryptographic
+ operations allowing to achieve performance gain for cryptodevs which use
+ CPU based acceleration, such as Intel AES-NI. An implementation for aesni_gcm
+ cryptodev is provided. The IPsec example application and ipsec library itself
+ were changed to allow utilization of this new feature.
+
* **Added handling of mixed algorithms in encrypted digest requests in QAT PMD.**
Added handling of mixed algorithms in encrypted digest hash-cipher
Such algorithm combinations are not supported on GEN1/GEN2 hardware
and executing the request returns RTE_CRYPTO_OP_STATUS_INVALID_SESSION.
+* **Queue-pairs are now thread-safe on Intel QuickAssist Technology (QAT) PMD.**
+
+ Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within
+ a single queue-pair all enqueues to the TX queue must be done from one thread
+ and all dequeues from the RX queue must be done from one thread, but enqueues
+ and dequeues may be done in different threads.).
+
+* **Updated the ZUC PMD.**
+
+ * Transistioned underlying library from libSSO ZUC to intel-ipsec-mb
+ library (minimum version required 0.53).
+ * Removed dynamic library limitation, so PMD can be built as a shared
+ object now.
+
+* **Updated the KASUMI PMD.**
+
+ * Transistioned underlying library from libSSO KASUMI to intel-ipsec-mb
+ library (minimum version required 0.53).
+
+* **Updated the SNOW3G PMD.**
+
+ * Transistioned underlying library from libSSO SNOW3G to intel-ipsec-mb
+ library (minimum version required 0.53).
+
+* **Changed armv8 crypto PMD external dependency.**
+
+ armv8 crypto PMD now depends on Arm crypto library, and Marvell's
+ armv8 crypto library is not used anymore. Library name is changed
+ from armv8_crypto to AArch64crypto.
+
+* **Added inline IPsec support to Marvell OCTEON TX2 PMD.**
+
+ Added inline IPsec support to Marvell OCTEON TX2 PMD. With the feature,
+ applications would be able to offload entire IPsec offload to the hardware.
+ For the configured sessions, hardware will do the lookup and perform
+ decryption and IPsec transformation. For the outbound path, application
+ can submit a plain packet to the PMD, and it would be sent out on wire
+ after doing encryption and IPsec transformation of the packet.
+
* **Added Marvell OCTEON TX2 End Point rawdev PMD.**
Added a new OCTEON TX2 rawdev PMD for End Point mode of operation.
Add event device support for ``l3fwd`` sample application. It demonstrates
usage of poll and event mode IO mechanism under a single application.
+* **Added cycle-count mode to the compression performance tool.**
+
+ Enhanced the compression performance tool by adding a cycle-count mode
+ which can be used to help measure and tune hardware and software PMDs.
+
Removed Items
-------------
the Technical Board decided to disable all the kernel modules
by default from 20.02 version.
+* **Removed coalescing feature from Intel QuickAssist Technology (QAT) PMD.**
+
+ The internal tail write coalescing feature was removed as not compatible with
+ dual-thread feature. It was replaced with a threshold feature. At busy times
+ if only a small number of packets can be enqueued, each enqueue causes
+ an expensive MMIO write. These MMIO write occurrences can be optimised by using
+ the new threshold parameter on process start. Please see qat documentation for
+ more details.
