11 The text in the sections below explains how to update the release notes.
13 Use proper spelling, capitalization and punctuation in all sections.
15 Variable and config names should be quoted as fixed width text:

27 .. This section should contain new features added in this release.
30 * **Add a title in the past tense with a full stop.**
32 Add a short 1-2 sentence description in the past tense.
33 The description should be enough to allow someone scanning
34 the release notes to understand the new feature.
36 If the feature adds a lot of sub-features you can use a bullet list
39 * Added feature foo to do something.
40 * Enhanced feature bar to do something else.
42 Refer to the previous release notes for examples.
44 Suggested order in release notes items:
45 * Core libs (EAL, mempool, ring, mbuf, buses)
46 * Device abstraction libs and PMDs
48 - cryptodev (lib, PMDs)
49 - eventdev (lib, PMDs)
52 * Apps, Examples, Tools (if significant)

56 =======================================================
58 * **Updated Cisco enic driver.**
60 * Added support for VF representors with single-queue Tx/Rx and flow API
61 * Added support for egress PORT_ID action
62 * Added support for non-zero priorities for group 0 flows
64 * **Extended flow-perf application.**
66 * Started supporting user order instead of bit mask:
67 Now the user can create any structure of rte_flow
68 using flow performance application with any order,
69 moreover the app also now starts to support inner
70 items matching as well.
71 * Added header modify actions.
73 * Added raw encap/decap actions.
74 * Added VXLAN encap/decap actions.
75 * Added ICMP and ICMP6 matching items.
76 * Added option to set port mask for insertion/deletion:
78 where N represents the hexadecimal bitmask of ports used.
84 .. This section should contain removed items in this release. Sample format:
86 * Add a short 1-2 sentence description of the removed item

91 =======================================================
97 .. This section should contain API changes. Sample format:
99 * sample: Add a short 1-2 sentence description of the API change
100 which was announced in the previous releases and made in this release.
101 Start with a scope label like "ethdev:".
102 Use fixed width quotes for ``function_names`` or ``struct_names``.

107 =======================================================
109 * eal: The ``rte_logs`` struct and global symbol was made private
110 and is no longer part of the API.
112 * eal: Made the ``rte_dev_event`` structure private to the EAL as no public API
115 * mem: Removed the unioned field ``phys_addr`` from
116 the structures ``rte_memseg`` and ``rte_memzone``.
117 The field ``iova`` is remaining from the old unions.
119 * mempool: Removed the unioned fields ``phys_addr`` and ``physaddr`` from
120 the structures ``rte_mempool_memhdr`` and ``rte_mempool_objhdr``.
121 The field ``iova`` is remaining from the old unions.
122 The flag name ``MEMPOOL_F_NO_PHYS_CONTIG`` is removed,
123 while the aliased flag ``MEMPOOL_F_NO_IOVA_CONTIG`` is kept.
125 * mbuf: Removed the functions ``rte_mbuf_data_dma_addr*``
126 and the macros ``rte_pktmbuf_mtophys*``.
127 The same functionality is still available with the functions and macros
128 having ``iova`` in their names instead of ``dma_addr`` or ``mtophys``.
130 * mbuf: Removed the unioned field ``buf_physaddr`` from ``rte_mbuf``.
131 The field ``buf_iova`` is remaining from the old union.
133 * mbuf: Removed the unioned field ``refcnt_atomic`` from
134 the structures ``rte_mbuf`` and ``rte_mbuf_ext_shared_info``.
135 The field ``refcnt`` is remaining from the old unions.
137 * pci: Removed the ``rte_kernel_driver`` enum defined in rte_dev.h and
138 replaced with a private enum in the PCI subsystem.
140 * pci: Removed the PCI resources map API from the public API
141 (``pci_map_resource`` and ``pci_unmap_resource``) and moved it to the
142 PCI bus driver along with the PCI resources lists and associated structures
143 (``pci_map``, ``pci_msix_table``, ``mapped_pci_resource`` and
144 ``mapped_pci_res_list``).
146 * ethdev: Removed the ``kdrv`` field in the ethdev ``rte_eth_dev_data``
147 structure as it gave no useful abstracted information to the applications.
149 * ethdev: ``rte_eth_rx_descriptor_done()`` API has been deprecated.
151 * Renamed internal ethdev APIs:
153 * ``_rte_eth_dev_callback_process()`` -> ``rte_eth_dev_callback_process()``
154 * ``_rte_eth_dev_reset`` -> ``rte_eth_dev_internal_reset()``
156 * rawdev: Added a structure size parameter to the functions
157 ``rte_rawdev_queue_setup()``, ``rte_rawdev_queue_conf_get()``,
158 ``rte_rawdev_info_get()`` and ``rte_rawdev_configure()``,
159 allowing limited driver type-checking and ABI compatibility.
161 * rawdev: Changed the return type of the function ``rte_dev_info_get()``
162 and the function ``rte_rawdev_queue_conf_get()``
163 from ``void`` to ``int`` allowing the return of error codes from drivers.
165 * bpf: ``RTE_BPF_XTYPE_NUM`` has been dropped from ``rte_bpf_xtype``.
171 .. This section should contain ABI changes. Sample format:
173 * sample: Add a short 1-2 sentence description of the ABI change
174 which was announced in the previous releases and made in this release.
175 Start with a scope label like "ethdev:".
176 Use fixed width quotes for ``function_names`` or ``struct_names``.

180 Also, make sure to start the actual text at the margin.
181 =======================================================
185 * Following device operation function pointers moved
186 from ``struct eth_dev_ops`` to ``struct rte_eth_dev``:
188 * ``eth_rx_queue_count_t rx_queue_count;``
189 * ``eth_rx_descriptor_done_t rx_descriptor_done;``
190 * ``eth_rx_descriptor_status_t rx_descriptor_status;``
191 * ``eth_tx_descriptor_status_t tx_descriptor_status;``
193 * ``struct eth_dev_ops`` is no more accessible by applications,
194 which was already internal data structure.
196 * ``ethdev`` internal functions are marked with ``__rte_internal`` tag.
202 .. This section should contain new known issues in this release. Sample format:
204 * **Add title in present tense with full stop.**
206 Add a short 1-2 sentence description of the known issue
207 in the present tense. Add information on any known workarounds.
209 This section is a comment. Do not overwrite or remove it.
210 Also, make sure to start the actual text at the margin.
211 =======================================================
217 .. This section should contain a list of platforms that were tested
222 * <vendor> platform with <vendor> <type of devices> combinations
227 * Other relevant details...
