57 =========================================================

62 16-bit, 32-bit, 64-bit value.
64 * **Updated rte_flow api to support L2TPv3 over IP flows.**
66 Added support for new flow item to handle L2TPv3 over IP rte_flow patterns.
68 * **Added IONIC net PMD.**

77 * Added support for Rx interrupt.
78 * Added support setting VF MAC address by PF driver.
80 * **Updated the Intel ice driver.**
82 Updated the Intel ice driver with new features and improvements, including:
84 * Added support for MAC rules on specific port.
85 * Added support for MAC/VLAN with TCP/UDP in switch rule.
86 * Added support for 1/10G device.
88 * **Updated Intel iavf driver.**
90 Updated iavf PMD with new features and improvements, including:
92 * Added more supported device IDs.
93 * Updated virtual channel to latest AVF spec.
95 * **Updated Intel i40e driver.**
97 Updated i40e PMD with new features and improvements, including:
99 * Added support for L2TPv3 over IP profiles which can be programmed by the
100 dynamic device personalization (DDP) process.
101 * Added support for ESP-AH profiles which can be programmed by the
102 dynamic device personalization (DDP) process.
103 * Added PF support Malicious Device Drive event catch and notify.
104 * Added LLDP support.
105 * Extended PHY access AQ cmd.
106 * Added support for reading LPI counters.
107 * Added support for Energy Efficient Ethernet
109 * **Updated Mellanox mlx5 driver.**
111 Updated Mellanox mlx5 driver with new features and improvements, including:
113 * Added support for RSS using L3/L4 source/destination only.
114 * Added support for matching on GTP tunnel header item.
116 * **Add new vDPA PMD based on Mellanox devices**
118 Added a new Mellanox vDPA (``mlx5_vdpa``) PMD.
119 See the :doc:`../vdpadevs/mlx5` guide for more details on this driver.
121 * **Updated testpmd application.**
123 Added support for ESP and L2TPv3 over IP rte_flow patterns to the testpmd
126 * **Added algorithms to cryptodev API.**
128 * ECDSA (Elliptic Curve Digital Signature Algorithm) is added to
129 asymmetric crypto library specifications.
130 * ECPM (Elliptic Curve Point Multiplication) is added to
131 asymmetric crypto library specifications.
133 * **Added synchronous Crypto burst API.**
135 A new API is introduced in crypto library to handle synchronous cryptographic
136 operations allowing to achieve performance gain for cryptodevs which use
137 CPU based acceleration, such as Intel AES-NI. An implementation for aesni_gcm
138 cryptodev is provided. The IPsec example application and ipsec library itself
139 were changed to allow utilization of this new feature.
141 * **Added handling of mixed algorithms in encrypted digest requests in QAT PMD.**
143 Added handling of mixed algorithms in encrypted digest hash-cipher
144 (generation) and cipher-hash (verification) requests (e.g. SNOW3G + ZUC or
145 ZUC + AES CTR) in QAT PMD possible when running on GEN3 QAT hardware.
146 Such algorithm combinations are not supported on GEN1/GEN2 hardware
147 and executing the request returns RTE_CRYPTO_OP_STATUS_INVALID_SESSION.
149 * **Updated the ZUC PMD.**
151 * Transistioned underlying library from libSSO ZUC to intel-ipsec-mb
152 library (minimum version required 0.53).
153 * Removed dynamic library limitation, so PMD can be built as a shared
156 * **Updated the KASUMI PMD.**
158 * Transistioned underlying library from libSSO KASUMI to intel-ipsec-mb
159 library (minimum version required 0.53).
161 * **Updated the SNOW3G PMD.**
163 * Transistioned underlying library from libSSO SNOW3G to intel-ipsec-mb
164 library (minimum version required 0.53).
166 * **Changed armv8 crypto PMD external dependency.**
168 armv8 crypto PMD now depends on Arm crypto library, and Marvell's
169 armv8 crypto library is not used anymore. Library name is changed
170 from armv8_crypto to AArch64crypto.
172 * **Added inline IPsec support to Marvell OCTEON TX2 PMD.**
174 Added inline IPsec support to Marvell OCTEON TX2 PMD. With the feature,
175 applications would be able to offload entire IPsec offload to the hardware.
176 For the configured sessions, hardware will do the lookup and perform
177 decryption and IPsec transformation. For the outbound path, application
178 can submit a plain packet to the PMD, and it would be sent out on wire
179 after doing encryption and IPsec transformation of the packet.
181 * **Added Marvell OCTEON TX2 End Point rawdev PMD.**
183 Added a new OCTEON TX2 rawdev PMD for End Point mode of operation.
184 See the :doc:`../rawdevs/octeontx2_ep` for more details on this new PMD.
186 * **Added event mode to l3fwd sample application.**
188 Add event device support for ``l3fwd`` sample application. It demonstrates
189 usage of poll and event mode IO mechanism under a single application.
