35 If the feature adds a lot of sub-features you can use a bullet list
38 * Added feature foo to do something.
39 * Enhanced feature bar to do something else.
41 Refer to the previous release notes for examples.

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 * **Updated KNI module and PMD.**
73 Updated the KNI kernel module to set the max_mtu according to the given
74 initial MTU size. Without it, the maximum MTU was 1500.
76 Updated the KNI PMD driver to set the mbuf_size and MTU based on
77 the given mb-pool. This provide the ability to pass jumbo frames
78 if the mb-pool contains suitable buffers' size.
80 * **Added the AF_XDP PMD.**
82 Added a Linux-specific PMD driver for AF_XDP, it can create the AF_XDP socket
83 and bind it to a specific netdev queue, it allows a DPDK application to send
84 and receive raw packets through the socket which would bypass the kernel
85 network stack to achieve high performance packet processing.
87 * **Added a net PMD NFB.**
89 Added the new ``nfb`` net driver for Netcope NFB cards. See
90 the :doc:`../nics/nfb` NIC guide for more details on this new driver.
92 * **Updated Solarflare network PMD.**
94 Updated the sfc_efx driver including the following changes:
96 * Added support for Rx descriptor status and related API in a secondary
98 * Added support for Tx descriptor status API in a secondary process.
99 * Added support for RSS RETA and hash configuration get API in a secondary
101 * Added support for Rx packet types list in a secondary process.
102 * Added Tx prepare to do Tx offloads checks.
103 * Added support for VXLAN and GENEVE encapsulated TSO.
105 * **Updated Mellanox drivers.**
107 New features and improvements were done in mlx4 and mlx5 PMDs:
109 * Added firmware version reading.
111 * **Renamed avf to iavf.**
113 Renamed Intel Ethernet Adaptive Virtual Function driver ``avf`` to ``iavf``,
114 which includes the directory name, lib name, filenames, makefile, docs,
115 macros, functions, structs and any other strings in the code.
117 * **Updated the enic driver.**
119 * Fixed several flow (director) bugs related to MARK, SCTP, VLAN, VXLAN, and
120 inner packet matching.
121 * Added limited support for RAW.
122 * Added limited support for RSS.
123 * Added limited support for PASSTHRU.
125 * **Updated the ixgbe driver.**
129 * Added promiscuous mode support.
131 * **Updated the ice driver.**
133 * Added support of SSE and AVX2 instructions in Rx and Tx paths.
134 * Added package download support.
135 * Added Safe Mode support.
136 * Supported RSS for UPD/TCP/SCTP+IPV4/IPV6 packets.
138 * **Updated the i40e driver.**
142 * Added support for VXLAN-GPE packet.
143 * Added support for VXLAN-GPE classification.
145 * **Updated the ENETC driver.**
149 * Added physical addressing mode support
150 * Added SXGMII interface support
152 * **Updated the QuickAssist Technology PMD.**
154 Added support for AES-XTS with 128 and 256 bit AES keys.
156 * **Updated AESNI-MB PMD.**
158 Added support for out-of-place operations.
160 * **Updated the IPsec library.**
162 The IPsec library has been updated with AES-CTR and 3DES-CBC cipher algorithms
163 support. The related ipsec-secgw test scripts have been added.
165 * **Updated the testpmd application.**
167 Improved testpmd application performance on ARM platform. For ``macswap``
168 forwarding mode, NEON intrinsics were used to do swap to save CPU cycles.
174 .. This section should contain removed items in this release. Sample format:
176 * Add a short 1-2 sentence description of the removed item
179 This section is a comment. Do not overwrite or remove it.
180 Also, make sure to start the actual text at the margin.
181 =========================================================
187 .. This section should contain API changes. Sample format:
189 * sample: Add a short 1-2 sentence description of the API change
190 which was announced in the previous releases and made in this release.
191 Start with a scope label like "ethdev:".
192 Use fixed width quotes for ``function_names`` or ``struct_names``.
195 This section is a comment. Do not overwrite or remove it.
196 Also, make sure to start the actual text at the margin.
197 =========================================================
199 * eal: the type of the ``attr_value`` parameter of the function
200 ``rte_service_attr_get()`` has been changed
201 from ``uint32_t *`` to ``uint64_t *``.
203 * meter: replace ``enum rte_meter_color`` in meter library with new
204 ``rte_color`` definition added in 19.02. To consolidate mulitple color
205 definitions replicated at many places such as: rte_mtr.h, rte_tm.h,
206 replacements with rte_color values are done.
208 * vfio: Functions ``rte_vfio_container_dma_map`` and
209 ``rte_vfio_container_dma_unmap`` have been extended with an option to
210 request mapping or un-mapping to the default vfio container fd.
216 .. This section should contain ABI changes. Sample format:
218 * sample: Add a short 1-2 sentence description of the ABI change
219 which was announced in the previous releases and made in this release.
220 Start with a scope label like "ethdev:".
221 Use fixed width quotes for ``function_names`` or ``struct_names``.
224 This section is a comment. Do not overwrite or remove it.
225 Also, make sure to start the actual text at the margin.
226 =========================================================
228 * ethdev: Additional fields in rte_eth_dev_info.
230 The ``rte_eth_dev_info`` structure has had two extra fields
231 added: ``min_mtu`` and ``max_mtu``. Each of these are of type ``uint16_t``.
232 The values of these fields can be set specifically by the PMD drivers as
233 supported values can vary from device to device.
235 * cryptodev: in 18.08 new structure ``rte_crypto_asym_op`` was introduced and
236 included into ``rte_crypto_op``. As ``rte_crypto_asym_op`` structure was
237 defined as cache-line aligned that caused unintended changes in
238 ``rte_crypto_op`` structure layout and alignment. Remove cache-line
239 alignment for ``rte_crypto_asym_op`` to restore expected ``rte_crypto_op``
240 layout and alignment.
