127 * **Add new vDPA PMD based on Mellanox devices**
129 Added a new Mellanox vDPA (``mlx5_vdpa``) PMD.
130 See the :doc:`../vdpadevs/mlx5` guide for more details on this driver.
132 * **Added support for virtio-PMD notification data.**
134 Added support for virtio-PMD notification data so that the driver
135 passes extra data (besides identifying the virtqueue) in its device
136 notifications, expanding the notifications to include the avail index and
137 avail wrap counter (When split ring is used, the avail wrap counter is not
138 included in the notification data).
140 * **Updated testpmd application.**
142 Added support for ESP and L2TPv3 over IP rte_flow patterns to the testpmd
145 * **Added algorithms to cryptodev API.**
147 * ECDSA (Elliptic Curve Digital Signature Algorithm) is added to
148 asymmetric crypto library specifications.
149 * ECPM (Elliptic Curve Point Multiplication) is added to
150 asymmetric crypto library specifications.
152 * **Added synchronous Crypto burst API.**
154 A new API is introduced in crypto library to handle synchronous cryptographic
155 operations allowing to achieve performance gain for cryptodevs which use
156 CPU based acceleration, such as Intel AES-NI. An implementation for aesni_gcm
157 cryptodev is provided. The IPsec example application and ipsec library itself
158 were changed to allow utilization of this new feature.
160 * **Added handling of mixed algorithms in encrypted digest requests in QAT PMD.**
162 Added handling of mixed algorithms in encrypted digest hash-cipher
163 (generation) and cipher-hash (verification) requests (e.g. SNOW3G + ZUC or
164 ZUC + AES CTR) in QAT PMD possible when running on GEN3 QAT hardware.
165 Such algorithm combinations are not supported on GEN1/GEN2 hardware
166 and executing the request returns RTE_CRYPTO_OP_STATUS_INVALID_SESSION.
168 * **Queue-pairs are now thread-safe on Intel QuickAssist Technology (QAT) PMD.**
170 Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within
171 a single queue-pair all enqueues to the TX queue must be done from one thread
172 and all dequeues from the RX queue must be done from one thread, but enqueues
173 and dequeues may be done in different threads.).
175 * **Updated the ZUC PMD.**
177 * Transistioned underlying library from libSSO ZUC to intel-ipsec-mb
178 library (minimum version required 0.53).
179 * Removed dynamic library limitation, so PMD can be built as a shared
182 * **Updated the KASUMI PMD.**
184 * Transistioned underlying library from libSSO KASUMI to intel-ipsec-mb
185 library (minimum version required 0.53).
187 * **Updated the SNOW3G PMD.**
189 * Transistioned underlying library from libSSO SNOW3G to intel-ipsec-mb
190 library (minimum version required 0.53).
192 * **Changed armv8 crypto PMD external dependency.**
194 armv8 crypto PMD now depends on Arm crypto library, and Marvell's
195 armv8 crypto library is not used anymore. Library name is changed
196 from armv8_crypto to AArch64crypto.
198 * **Added inline IPsec support to Marvell OCTEON TX2 PMD.**
200 Added inline IPsec support to Marvell OCTEON TX2 PMD. With the feature,
201 applications would be able to offload entire IPsec offload to the hardware.
202 For the configured sessions, hardware will do the lookup and perform
203 decryption and IPsec transformation. For the outbound path, application
204 can submit a plain packet to the PMD, and it would be sent out on wire
205 after doing encryption and IPsec transformation of the packet.
207 * **Added Marvell OCTEON TX2 End Point rawdev PMD.**
209 Added a new OCTEON TX2 rawdev PMD for End Point mode of operation.
210 See the :doc:`../rawdevs/octeontx2_ep` for more details on this new PMD.
212 * **Added event mode to l3fwd sample application.**
214 Add event device support for ``l3fwd`` sample application. It demonstrates
215 usage of poll and event mode IO mechanism under a single application.
217 * **Added cycle-count mode to the compression performance tool.**
219 Enhanced the compression performance tool by adding a cycle-count mode
220 which can be used to help measure and tune hardware and software PMDs.

233 =========================================================
235 * **Disabled building all the Linux kernel modules by default.**
237 In order to remove the build time dependency with Linux kernel,
238 the Technical Board decided to disable all the kernel modules
239 by default from 20.02 version.
241 * **Removed coalescing feature from Intel QuickAssist Technology (QAT) PMD.**
243 The internal tail write coalescing feature was removed as not compatible with
244 dual-thread feature. It was replaced with a threshold feature. At busy times
245 if only a small number of packets can be enqueued, each enqueue causes
246 an expensive MMIO write. These MMIO write occurrences can be optimised by using
247 the new threshold parameter on process start. Please see qat documentation for
