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
63 * Added support for VXLAN decap combined with VLAN pop
65 * **Extended flow-perf application.**
67 * Started supporting user order instead of bit mask:
68 Now the user can create any structure of rte_flow
69 using flow performance application with any order,
70 moreover the app also now starts to support inner
71 items matching as well.
72 * Added header modify actions.
74 * Added raw encap/decap actions.
75 * Added VXLAN encap/decap actions.
76 * Added ICMP and ICMP6 matching items.
77 * Added option to set port mask for insertion/deletion:
79 where N represents the hexadecimal bitmask of ports used.
85 .. This section should contain removed items in this release. Sample format:

92 =======================================================
98 .. This section should contain API changes. Sample format:
100 * sample: Add a short 1-2 sentence description of the API change
101 which was announced in the previous releases and made in this release.
102 Start with a scope label like "ethdev:".
103 Use fixed width quotes for ``function_names`` or ``struct_names``.

108 =======================================================
110 * build macros: The macros defining ``RTE_MACHINE_CPUFLAG_*`` are removed.
111 The information provided by these macros is available through standard
114 * eal: The ``rte_logs`` struct and global symbol was made private
115 and is no longer part of the API.
117 * eal: Made the ``rte_dev_event`` structure private to the EAL as no public API
120 * eal: ``rte_cio_rmb()`` and ``rte_cio_wmb()`` were deprecated since 20.08
121 and are removed in this release.
123 * mem: Removed the unioned field ``phys_addr`` from
124 the structures ``rte_memseg`` and ``rte_memzone``.
125 The field ``iova`` is remaining from the old unions.
127 * mempool: Removed the unioned fields ``phys_addr`` and ``physaddr`` from
128 the structures ``rte_mempool_memhdr`` and ``rte_mempool_objhdr``.
129 The field ``iova`` is remaining from the old unions.
130 The flag name ``MEMPOOL_F_NO_PHYS_CONTIG`` is removed,
131 while the aliased flag ``MEMPOOL_F_NO_IOVA_CONTIG`` is kept.
133 * mbuf: Removed the functions ``rte_mbuf_data_dma_addr*``
134 and the macros ``rte_pktmbuf_mtophys*``.
135 The same functionality is still available with the functions and macros
136 having ``iova`` in their names instead of ``dma_addr`` or ``mtophys``.
138 * mbuf: Removed the unioned field ``buf_physaddr`` from ``rte_mbuf``.
139 The field ``buf_iova`` is remaining from the old union.
141 * mbuf: Removed the unioned field ``refcnt_atomic`` from
142 the structures ``rte_mbuf`` and ``rte_mbuf_ext_shared_info``.
143 The field ``refcnt`` is remaining from the old unions.
145 * pci: Removed the ``rte_kernel_driver`` enum defined in rte_dev.h and
146 replaced with a private enum in the PCI subsystem.
148 * pci: Removed the PCI resources map API from the public API
149 (``pci_map_resource`` and ``pci_unmap_resource``) and moved it to the
150 PCI bus driver along with the PCI resources lists and associated structures
151 (``pci_map``, ``pci_msix_table``, ``mapped_pci_resource`` and
152 ``mapped_pci_res_list``).
154 * ethdev: Removed the ``kdrv`` field in the ethdev ``rte_eth_dev_data``
155 structure as it gave no useful abstracted information to the applications.
157 * ethdev: ``rte_eth_rx_descriptor_done()`` API has been deprecated.
159 * Renamed internal ethdev APIs:
161 * ``_rte_eth_dev_callback_process()`` -> ``rte_eth_dev_callback_process()``
162 * ``_rte_eth_dev_reset`` -> ``rte_eth_dev_internal_reset()``
164 * rawdev: Added a structure size parameter to the functions
165 ``rte_rawdev_queue_setup()``, ``rte_rawdev_queue_conf_get()``,
166 ``rte_rawdev_info_get()`` and ``rte_rawdev_configure()``,
167 allowing limited driver type-checking and ABI compatibility.
169 * rawdev: Changed the return type of the function ``rte_dev_info_get()``
170 and the function ``rte_rawdev_queue_conf_get()``
171 from ``void`` to ``int`` allowing the return of error codes from drivers.
173 * bpf: ``RTE_BPF_XTYPE_NUM`` has been dropped from ``rte_bpf_xtype``.
179 .. This section should contain ABI changes. Sample format:
181 * sample: Add a short 1-2 sentence description of the ABI change
182 which was announced in the previous releases and made in this release.
183 Start with a scope label like "ethdev:".
184 Use fixed width quotes for ``function_names`` or ``struct_names``.

188 Also, make sure to start the actual text at the margin.
189 =======================================================
193 * Following device operation function pointers moved
194 from ``struct eth_dev_ops`` to ``struct rte_eth_dev``:
196 * ``eth_rx_queue_count_t rx_queue_count;``
197 * ``eth_rx_descriptor_done_t rx_descriptor_done;``
198 * ``eth_rx_descriptor_status_t rx_descriptor_status;``
199 * ``eth_tx_descriptor_status_t tx_descriptor_status;``
201 * ``struct eth_dev_ops`` is no more accessible by applications,
202 which was already internal data structure.
204 * ``ethdev`` internal functions are marked with ``__rte_internal`` tag.
210 .. This section should contain new known issues in this release. Sample format:
212 * **Add title in present tense with full stop.**
214 Add a short 1-2 sentence description of the known issue
215 in the present tense. Add information on any known workarounds.

230 * <vendor> platform with <vendor> <type of devices> combinations
235 * Other relevant details...
