55 =========================================================
57 * **Added Stack API.**
59 Added a new stack API for configuration and use of a bounded stack of
60 pointers. The API provides MT-safe push and pop operations that can operate
61 on one or more pointers per operation.
63 The library supports two stack implementations: standard (lock-based) and lock-free.
64 The lock-free implementation is currently limited to x86-64 platforms.
66 * **Added Lock-Free Stack Mempool Handler.**
68 Added a new lock-free stack handler, which uses the newly added stack
71 * **Added RCU library.**
73 Added RCU library supporting quiescent state based memory reclamation method.
74 This library helps identify the quiescent state of the reader threads so
75 that the writers can free the memory associated with the lock free data
78 * **Updated KNI module and PMD.**
80 Updated the KNI kernel module to set the max_mtu according to the given
81 initial MTU size. Without it, the maximum MTU was 1500.
83 Updated the KNI PMD driver to set the mbuf_size and MTU based on
84 the given mb-pool. This provide the ability to pass jumbo frames
85 if the mb-pool contains suitable buffers' size.
87 * **Added the AF_XDP PMD.**
89 Added a Linux-specific PMD driver for AF_XDP, it can create the AF_XDP socket
90 and bind it to a specific netdev queue, it allows a DPDK application to send
91 and receive raw packets through the socket which would bypass the kernel
92 network stack to achieve high performance packet processing.
94 * **Added a net PMD NFB.**
96 Added the new ``nfb`` net driver for Netcope NFB cards. See
97 the :doc:`../nics/nfb` NIC guide for more details on this new driver.
99 * **Added IPN3KE net PMD.**
101 Added the new ``ipn3ke`` net driver for IntelĀ® FPGA PAC(Programmable
102 Acceleration Card) N3000. See the :doc:`../nics/ipn3ke` NIC guide for more
103 details on this new driver.
105 Aside from this, ifpga_rawdev is also updated to support IntelĀ® FPGA PAC
106 N3000 with SPI interface access, I2C Read/Write and Ethernet PHY configuration.
108 * **Updated Solarflare network PMD.**
110 Updated the sfc_efx driver including the following changes:
112 * Added support for Rx descriptor status and related API in a secondary
114 * Added support for Tx descriptor status API in a secondary process.
115 * Added support for RSS RETA and hash configuration get API in a secondary
117 * Added support for Rx packet types list in a secondary process.
118 * Added Tx prepare to do Tx offloads checks.
119 * Added support for VXLAN and GENEVE encapsulated TSO.
121 * **Updated Mellanox drivers.**
123 New features and improvements were done in mlx4 and mlx5 PMDs:
125 * Added firmware version reading.
127 * **Renamed avf to iavf.**
129 Renamed Intel Ethernet Adaptive Virtual Function driver ``avf`` to ``iavf``,
130 which includes the directory name, lib name, filenames, makefile, docs,
131 macros, functions, structs and any other strings in the code.
133 * **Updated the enic driver.**
135 * Fixed several flow (director) bugs related to MARK, SCTP, VLAN, VXLAN, and
136 inner packet matching.
137 * Added limited support for RAW.
138 * Added limited support for RSS.
139 * Added limited support for PASSTHRU.

183 * **Added Intel QuickAssist Technology PMD for asymmetric crypto.**
185 A new QAT Crypto PMD has been added, which provides asymmetric cryptography
186 algorithms, in this release modular exponentiation and modular multiplicative
187 inverse algorithms were added.
189 * **Updated AESNI-MB PMD.**
191 Added support for out-of-place operations.
193 * **Updated the IPsec library.**
195 The IPsec library has been updated with AES-CTR and 3DES-CBC cipher algorithms
196 support. The related ipsec-secgw test scripts have been added.
198 * **Updated the testpmd application.**
200 Improved testpmd application performance on ARM platform. For ``macswap``
201 forwarding mode, NEON intrinsics were used to do swap to save CPU cycles.
203 * **Updated power management library.**
205 Added support for Intel Speed Select Technology - Base Frequency (SST-BF).
206 ``rte_power_get_capabilities`` now has a bit in it's returned mask
207 indicating it's a high frequency core.
209 * **Updated distributor sample application.**
211 Added support for Intel SST-BF feature so that the distributor core is
212 pinned to a high frequency core if available.
218 .. This section should contain removed items in this release. Sample format:

225 =========================================================
231 .. This section should contain API changes. Sample format:
233 * sample: Add a short 1-2 sentence description of the API change
234 which was announced in the previous releases and made in this release.
235 Start with a scope label like "ethdev:".
236 Use fixed width quotes for ``function_names`` or ``struct_names``.
239 This section is a comment. Do not overwrite or remove it.
240 Also, make sure to start the actual text at the margin.
241 =========================================================
243 * eal: the type of the ``attr_value`` parameter of the function
244 ``rte_service_attr_get()`` has been changed
245 from ``uint32_t *`` to ``uint64_t *``.
247 * meter: replace ``enum rte_meter_color`` in meter library with new
248 ``rte_color`` definition added in 19.02. To consolidate mulitple color
249 definitions replicated at many places such as: rte_mtr.h, rte_tm.h,
250 replacements with rte_color values are done.
252 * vfio: Functions ``rte_vfio_container_dma_map`` and
253 ``rte_vfio_container_dma_unmap`` have been extended with an option to
254 request mapping or un-mapping to the default vfio container fd.
256 * power: ``rte_power_set_env`` and ``rte_power_unset_env`` functions
257 have been modified to be thread safe.
263 .. This section should contain ABI changes. Sample format:
265 * sample: Add a short 1-2 sentence description of the ABI change
266 which was announced in the previous releases and made in this release.
267 Start with a scope label like "ethdev:".
268 Use fixed width quotes for ``function_names`` or ``struct_names``.

272 Also, make sure to start the actual text at the margin.
273 =========================================================
275 * ethdev: Additional fields in rte_eth_dev_info.
277 The ``rte_eth_dev_info`` structure has had two extra fields
278 added: ``min_mtu`` and ``max_mtu``. Each of these are of type ``uint16_t``.
279 The values of these fields can be set specifically by the PMD drivers as
280 supported values can vary from device to device.
282 * cryptodev: in 18.08 new structure ``rte_crypto_asym_op`` was introduced and
283 included into ``rte_crypto_op``. As ``rte_crypto_asym_op`` structure was
284 defined as cache-line aligned that caused unintended changes in
285 ``rte_crypto_op`` structure layout and alignment. Remove cache-line
286 alignment for ``rte_crypto_asym_op`` to restore expected ``rte_crypto_op``
287 layout and alignment.
