264 Also, make sure to start the actual text at the margin.
265 =======================================================
267 * Removed support for Intel DLB V1 hardware. This is not a broad market device,
268 and existing customers already obtain the source code directly from Intel.
274 .. This section should contain API changes. Sample format:
276 * sample: Add a short 1-2 sentence description of the API change
277 which was announced in the previous releases and made in this release.
278 Start with a scope label like "ethdev:".
279 Use fixed width quotes for ``function_names`` or ``struct_names``.
282 This section is a comment. Do not overwrite or remove it.
283 Also, make sure to start the actual text at the margin.
284 =======================================================
286 * eal: The experimental TLS API added in ``rte_thread.h`` has been renamed
287 from ``rte_thread_tls_*`` to ``rte_thread_*`` to avoid naming redundancy
288 and confusion with the transport layer security term.
290 * pci: The value ``PCI_ANY_ID`` is marked as deprecated
291 and can be replaced with ``RTE_PCI_ANY_ID``.
293 * ethdev: Added a ``rte_flow`` pointer parameter to the function
294 ``rte_flow_dev_dump()`` allowing dump for single flow.
296 * cryptodev: The experimental raw data path API for dequeue
297 ``rte_cryptodev_raw_dequeue_burst`` got a new parameter
298 ``max_nb_to_dequeue`` to provide flexible control on dequeue.
300 * ethdev: The experimental flow API for shared action has been generalized
301 as a flow action handle used in rules through an indirect action.
302 The functions ``rte_flow_shared_action_*`` manipulating the action object
303 are replaced with ``rte_flow_action_handle_*``.
304 The action ``RTE_FLOW_ACTION_TYPE_SHARED`` is deprecated and can be
305 replaced with ``RTE_FLOW_ACTION_TYPE_INDIRECT``.
311 .. This section should contain ABI changes. Sample format:

321 =======================================================
323 * No ABI change that would break compatibility with 20.11.
325 * The experimental function ``rte_telemetry_legacy_register`` has been
326 removed from the public API and is now an internal-only function. This
327 function was already marked as internal in the API documentation for it,
328 and was not for use by external applications.
334 .. This section should contain new known issues in this release. Sample format:
336 * **Add title in present tense with full stop.**
338 Add a short 1-2 sentence description of the known issue
339 in the present tense. Add information on any known workarounds.
