Added support for new flow item to handle L2TPv3 over IP rte_flow patterns.
+* **Added IONIC net PMD.**
+
+ Added the new ``ionic`` net driver for Pensando Ethernet Network Adapters.
+ See the :doc:`../nics/ionic` NIC guide for more details on this new driver.
+
+* **Updated Broadcom bnxt driver**
+
+ Updated Broadcom bnxt driver with new features and improvements, including:
+
+ * Added support for MARK action.
+
* **Updated Hisilicon hns3 driver.**
Updated Hisilicon hns3 driver with new features and improvements, including:
Updated Mellanox mlx5 driver with new features and improvements, including:
* Added support for RSS using L3/L4 source/destination only.
+ * Added support for matching on GTP tunnel header item.
+
+* **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.
* **Updated testpmd application.**
* **Added algorithms to cryptodev API.**
- * Chacha20-Poly1305 AEAD algorithm can now be supported in cryptodev.
* ECDSA (Elliptic Curve Digital Signature Algorithm) is added to
asymmetric crypto library specifications.
* 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.
-* **Updated the Intel QuickAssist Technology (QAT) symmetric crypto PMD.**
+* **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.**
- Added Chacha20-Poly1305 AEAD algorithm.
+ * 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.
See the :doc:`../rawdevs/octeontx2_ep` for more details on this new PMD.
+* **Added event mode to l3fwd sample application.**
+
+ 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.
