26 .. This section should contain new features added in this release.
29 * **Add a title in the past tense with a full stop.**
31 Add a short 1-2 sentence description in the past tense.
32 The description should be enough to allow someone scanning
33 the release notes to understand the new feature.
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.
43 Suggested order in release notes items:
44 * Core libs (EAL, mempool, ring, mbuf, buses)
45 * Device abstraction libs and PMDs
47 - cryptodev (lib, PMDs)
48 - eventdev (lib, PMDs)
51 * Apps, Examples, Tools (if significant)

55 =========================================================
57 * **Updated KNI module and PMD.**
59 Updated the KNI kernel module to set the max_mtu according to the given
60 initial MTU size. Without it, the maximum MTU was 1500.
62 Updated the KNI PMD driver to set the mbuf_size and MTU based on
63 the given mb-pool. This provide the ability to pass jumbo frames
64 if the mb-pool contains suitable buffers' size.
66 * **Updated Solarflare network PMD.**
68 Updated the sfc_efx driver including the following changes:
70 * Added support for Rx descriptor status and related API in a secondary
72 * Added support for Tx descriptor status API in a secondary process.
73 * Added support for RSS RETA and hash configuration get API in a secondary
75 * Added support for Rx packet types list in a secondary process.
77 * **Updated Mellanox drivers.**
79 New features and improvements were done in mlx4 and mlx5 PMDs:
81 * Added firmware version reading.
83 * **Renamed avf to iavf.**
85 Renamed Intel Ethernet Adaptive Virtual Function driver ``avf`` to ``iavf``,
86 which includes the directory name, lib name, filenames, makefile, docs,
87 macros, functions, structs and any other strings in the code.
89 * **Updated the enic driver.**
91 * Fixed several flow (director) bugs related to MARK, SCTP, VLAN, VXLAN, and
92 inner packet matching.
93 * Added limited support for RAW.
94 * Added limited support for RSS.
95 * Added limited support for PASSTHRU.
97 * **Updated the ixgbe driver.**
101 * Added promiscuous mode support.
103 * **Updated the ice driver.**
105 * Added support of SSE and AVX2 instructions in Rx and Tx paths.
107 * **Updated the QuickAssist Technology PMD.**
109 Added support for AES-XTS with 128 and 256 bit AES keys.
111 * **Updated the IPsec library.**
113 The IPsec library has been updated with AES-CTR and 3DES-CBC cipher algorithms
114 support. The related ipsec-secgw test scripts have been added.
116 * **Updated the testpmd application.**
118 Improved testpmd application performance on ARM platform. For ``macswap``
119 forwarding mode, NEON intrinsics were used to do swap to save CPU cycles.
125 .. This section should contain removed items in this release. Sample format:
127 * Add a short 1-2 sentence description of the removed item

132 =========================================================
138 .. This section should contain API changes. Sample format:
140 * sample: Add a short 1-2 sentence description of the API change
141 which was announced in the previous releases and made in this release.
142 Start with a scope label like "ethdev:".
143 Use fixed width quotes for ``function_names`` or ``struct_names``.

147 Also, make sure to start the actual text at the margin.
148 =========================================================
150 * eal: the type of the ``attr_value`` parameter of the function
151 ``rte_service_attr_get()`` has been changed
152 from ``uint32_t *`` to ``uint64_t *``.
154 * vfio: Functions ``rte_vfio_container_dma_map`` and
155 ``rte_vfio_container_dma_unmap`` have been extended with an option to
156 request mapping or un-mapping to the default vfio container fd.
162 .. This section should contain ABI changes. Sample format:
164 * sample: Add a short 1-2 sentence description of the ABI change
165 which was announced in the previous releases and made in this release.
166 Start with a scope label like "ethdev:".
167 Use fixed width quotes for ``function_names`` or ``struct_names``.

172 =========================================================
174 * cryptodev: in 18.08 new structure ``rte_crypto_asym_op`` was introduced and
175 included into ``rte_crypto_op``. As ``rte_crypto_asym_op`` structure was
176 defined as cache-line aligned that caused unintended changes in
177 ``rte_crypto_op`` structure layout and alignment. Remove cache-line
178 alignment for ``rte_crypto_asym_op`` to restore expected ``rte_crypto_op``
179 layout and alignment.
