149 See the :doc:`../vdpadevs/mlx5` guide for more details on this driver.
151 * **Added support for virtio-PMD notification data.**
153 Added support for virtio-PMD notification data so that the driver
154 passes extra data (besides identifying the virtqueue) in its device
155 notifications, expanding the notifications to include the avail index and
156 avail wrap counter (When split ring is used, the avail wrap counter is not
157 included in the notification data).
159 * **Updated testpmd application.**
161 Added support for ESP and L2TPv3 over IP rte_flow patterns to the testpmd
164 * **Added algorithms to cryptodev API.**
166 Added new algorithms to the cryptodev API:
168 * ECDSA (Elliptic Curve Digital Signature Algorithm) is added to
169 asymmetric crypto library specifications.
170 * ECPM (Elliptic Curve Point Multiplication) is added to
171 asymmetric crypto library specifications.
173 * **Added synchronous Crypto burst API.**
175 A new API has been introduced in the crypto library to handle synchronous cryptographic
176 operations allowing it to achieve performance gains for cryptodevs which use
177 CPU based acceleration, such as Intel AES-NI. An implementation for aesni_gcm
178 cryptodev is provided. The IPsec example application and ipsec library itself
179 were changed to allow utilization of this new feature.
181 * **Added handling of mixed algorithms in encrypted digest requests in QAT PMD.**
183 Added handling of mixed algorithms in encrypted digest hash-cipher
184 (generation) and cipher-hash (verification) requests (e.g. SNOW3G + ZUC or
185 ZUC + AES CTR) in QAT PMD possible when running on GEN3 QAT hardware.
186 Such algorithm combinations are not supported on GEN1/GEN2 hardware
187 and executing the request returns ``RTE_CRYPTO_OP_STATUS_INVALID_SESSION``.
189 * **Queue-pairs are now thread-safe on Intel QuickAssist Technology (QAT) PMD.**
191 Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within
192 a single queue-pair all enqueues to the TX queue must be done from one thread
193 and all dequeues from the RX queue must be done from one thread, but enqueues
194 and dequeues may be done in different threads.).
196 * **Updated the ZUC PMD.**
198 * Transitioned underlying library from libSSO ZUC to intel-ipsec-mb
199 library (minimum version required 0.53).
200 * Removed dynamic library limitation, so PMD can be built as a shared
203 * **Updated the KASUMI PMD.**
205 * Transitioned underlying library from libSSO KASUMI to intel-ipsec-mb
206 library (minimum version required 0.53).
208 * **Updated the SNOW3G PMD.**
210 * Transitioned underlying library from libSSO SNOW3G to intel-ipsec-mb
211 library (minimum version required 0.53).
213 * **Changed armv8 crypto PMD external dependency.**
215 Changed armv8 crypto PMD external dependency. The
216 armv8 crypto PMD now depends on the Arm crypto library, and Marvell's
217 armv8 crypto library is not used anymore. The library name has been changed
218 from armv8_crypto to AArch64crypto.
220 * **Added inline IPsec support to Marvell OCTEON TX2 PMD.**
222 Added inline IPsec support to Marvell OCTEON TX2 PMD. With this feature,
223 applications will be able to offload entire IPsec offload to the hardware.
224 For the configured sessions, hardware will do the lookup and perform
225 decryption and IPsec transformation. For the outbound path, applications
226 can submit a plain packet to the PMD, and it will be sent out on the wire
227 after doing encryption and IPsec transformation of the packet.
229 * **Added Marvell OCTEON TX2 End Point rawdev PMD.**
231 Added a new OCTEON TX2 rawdev PMD for End Point mode of operation.
232 See the :doc:`../rawdevs/octeontx2_ep` for more details on this new PMD.
234 * **Added event mode to l3fwd sample application.**
236 Added event device support for the ``l3fwd`` sample application. It demonstrates
237 usage of poll and event mode IO mechanism under a single application.
239 * **Added cycle-count mode to the compression performance tool.**
241 Enhanced the compression performance tool by adding a cycle-count mode
242 which can be used to help measure and tune hardware and software PMDs.
244 * **Added OpenWrt howto guide.**
246 Added document which describes how to enable DPDK on OpenWrt in both virtual and

260 =========================================================
262 * **Disabled building all the Linux kernel modules by default.**
264 In order to remove the build time dependency on the Linux kernel,
265 the Technical Board decided to disable all the kernel modules
266 by default from 20.02 version.
268 * **Removed coalescing feature from Intel QuickAssist Technology (QAT) PMD.**
270 The internal tail write coalescing feature was removed as not compatible with
271 dual-thread feature. It was replaced with a threshold feature. At busy times
272 if only a small number of packets can be enqueued, each enqueue causes
273 an expensive MMIO write. These MMIO write occurrences can be optimized by using
274 the new threshold parameter on process start. Please see QAT documentation for
