36     like this:
37
38     * Added feature foo to do something.

40
41     Refer to the previous release notes for examples.
42
43     Suggested order in release notes items:
44     * Core libs (EAL, mempool, ring, mbuf, buses)
45     * Device abstraction libs and PMDs
46       - ethdev (lib, PMDs)
47       - cryptodev (lib, PMDs)
48       - eventdev (lib, PMDs)

55     =========================================================
56
57* **Updated KNI module and PMD.**
58
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.
61
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.
65
66* **Updated Solarflare network PMD.**
67
68  Updated the sfc_efx driver including the following changes:
69
70  * Added support for Rx descriptor status and related API in a secondary
71    process.
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
74    process.
75  * Added support for Rx packet types list in a secondary process.
76
77* **Updated Mellanox drivers.**
78
79   New features and improvements were done in mlx4 and mlx5 PMDs:
80
81   * Added firmware version reading.
82
83* **Renamed avf to iavf.**
84
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.
88

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.

98
99  New features for VF:
100
101  * Added promiscuous mode support.
102
103* **Updated the ice driver.**
104
105  * Added support of SSE and AVX2 instructions in Rx and Tx paths.
106  * Added package download support.
107  * Added Safe Mode support.
108  * Supported RSS for UPD/TCP/SCTP+IPV4/IPV6 packets.
109
110* **Updated the QuickAssist Technology PMD.**
111
112  Added support for AES-XTS with 128 and 256 bit AES keys.
113
114* **Updated AESNI-MB PMD.**
115
116  Added support for out-of-place operations.
117
118* **Updated the IPsec library.**
119

121  support. The related ipsec-secgw test scripts have been added.
122
123* **Updated the testpmd application.**
124
125  Improved testpmd application performance on ARM platform. For ``macswap``
126  forwarding mode, NEON intrinsics were used to do swap to save CPU cycles.

139   =========================================================
140
141
142API Changes
143-----------
144
145.. This section should contain API changes. Sample format:
146
147   * sample: Add a short 1-2 sentence description of the API change
148     which was announced in the previous releases and made in this release.
149     Start with a scope label like "ethdev:".
150     Use fixed width quotes for ``function_names`` or ``struct_names``.
151     Use the past tense.
152
153   This section is a comment. Do not overwrite or remove it.
154   Also, make sure to start the actual text at the margin.
155   =========================================================
156
157* eal: the type of the ``attr_value`` parameter of the function
158  ``rte_service_attr_get()`` has been changed
159  from ``uint32_t *`` to ``uint64_t *``.
160
161* vfio: Functions ``rte_vfio_container_dma_map`` and
162  ``rte_vfio_container_dma_unmap`` have been extended with an option to
163  request mapping or un-mapping to the default vfio container fd.
164
165
166ABI Changes
167-----------
168
169.. This section should contain ABI changes. Sample format:
170
171   * sample: Add a short 1-2 sentence description of the ABI change
172     which was announced in the previous releases and made in this release.
173     Start with a scope label like "ethdev:".
174     Use fixed width quotes for ``function_names`` or ``struct_names``.
175     Use the past tense.

178   Also, make sure to start the actual text at the margin.
179   =========================================================
180
181* ethdev: Additional fields in rte_eth_dev_info.
182
183  The ``rte_eth_dev_info`` structure has had two extra fields
184  added: ``min_mtu`` and ``max_mtu``. Each of these are of type ``uint16_t``.
185  The values of these fields can be set specifically by the PMD drivers as
186  supported values can vary from device to device.
187
188* cryptodev: in 18.08 new structure ``rte_crypto_asym_op`` was introduced and
189  included into ``rte_crypto_op``. As ``rte_crypto_asym_op`` structure was
190  defined as cache-line aligned that caused unintended changes in
191  ``rte_crypto_op`` structure layout and alignment. Remove cache-line
192  alignment for ``rte_crypto_asym_op`` to restore expected ``rte_crypto_op``
193  layout and alignment.
194
195
