124 ``rte_eth_tx_burst_mode_get`` that allow an application
125 to retrieve the mode information about RX/TX packet burst
126 such as Scalar or Vector, and Vector technology like AVX2.
127 Another new function ``rte_eth_burst_mode_option_name`` is

259 mechanism under a single application.
261 * **Added build support for Link Time Optimization.**
263 LTO is an optimization technique used by the compiler to perform whole
264 program analysis and optimization at link time. In order to do that
265 compilers store their internal representation of the source code that
266 the linker uses at the final stage of compilation process.
268 See :doc:`../prog_guide/lto` for more information:
274 .. This section should contain removed items in this release. Sample format:
276 * Add a short 1-2 sentence description of the removed item
279 This section is a comment. Do not overwrite or remove it.
280 Also, make sure to start the actual text at the margin.
281 =========================================================
283 * Removed duplicated set of commands for Rx offload configuration from testpmd::
285 port config all crc-strip|scatter|rx-cksum|rx-timestamp|
286 hw-vlan|hw-vlan-filter|hw-vlan-strip|hw-vlan-extend on|off
288 The testpmd commands set that can be used instead
289 in order to enable or disable Rx offloading on all Rx queues of a port is::
291 port config <port_id> rx_offload crc_strip|scatter|
292 ipv4_cksum|udp_cksum|tcp_cksum|timestamp|
293 vlan_strip|vlan_filter|vlan_extend on|off

307 dpaa and dpaa2 platforms.
313 .. This section should contain API changes. Sample format:
315 * sample: Add a short 1-2 sentence description of the API change
316 which was announced in the previous releases and made in this release.
317 Start with a scope label like "ethdev:".
318 Use fixed width quotes for ``function_names`` or ``struct_names``.
321 This section is a comment. Do not overwrite or remove it.
322 Also, make sure to start the actual text at the margin.
323 =========================================================
325 * eal: made the ``lcore_config`` struct and global symbol private.
327 * eal: removed the ``rte_cpu_check_supported`` function, replaced by
328 ``rte_cpu_is_supported`` since dpdk v17.08.
330 * eal: removed the ``rte_malloc_virt2phy`` function, replaced by
331 ``rte_malloc_virt2iova`` since v17.11.
333 * eal: made the ``rte_config`` struct and ``rte_eal_get_configuration``
336 * mem: hid the internal ``malloc_heap`` structure and the
337 ``rte_malloc_heap.h`` header.
339 * vfio: removed ``rte_vfio_dma_map`` and ``rte_vfio_dma_unmap`` that have
340 been marked as deprecated in release 19.05.
341 ``rte_vfio_container_dma_map`` and ``rte_vfio_container_dma_unmap`` can
342 be used as substitutes.
344 * pci: removed the following functions deprecated since dpdk v17.11:
346 - ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
347 - ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
348 - ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
350 * The network structure ``esp_tail`` has been prefixed by ``rte_``.
352 * The network definitions of PPPoE ethertypes have been prefixed by ``RTE_``.
354 * The network structure for MPLS has been prefixed by ``rte_``.
356 * ethdev: changed ``rte_eth_dev_infos_get`` return value from ``void`` to
357 ``int`` to provide a way to report various error conditions.
359 * ethdev: changed ``rte_eth_promiscuous_enable`` and
360 ``rte_eth_promiscuous_disable`` return value from ``void`` to ``int`` to
361 provide a way to report various error conditions.
363 * ethdev: changed ``rte_eth_allmulticast_enable`` and
364 ``rte_eth_allmulticast_disable`` return value from ``void`` to ``int`` to
365 provide a way to report various error conditions.
367 * ethdev: changed ``rte_eth_dev_xstats_reset`` return value from ``void`` to
368 ``int`` to provide a way to report various error conditions.
370 * ethdev: changed ``rte_eth_link_get`` and ``rte_eth_link_get_nowait``
371 return value from ``void`` to ``int`` to provide a way to report various
374 * ethdev: changed ``rte_eth_macaddr_get`` return value from ``void`` to
375 ``int`` to provide a way to report various error conditions.
377 * ethdev: changed ``rte_eth_dev_owner_delete`` return value from ``void`` to
378 ``int`` to provide a way to report various error conditions.
380 * ethdev: The deprecated function ``rte_eth_dev_count`` was removed.
381 The function ``rte_eth_dev_count_avail`` is a drop-in replacement.
382 If the intent is to iterate over ports, ``RTE_ETH_FOREACH_*`` macros
383 are better port iterators.
385 * event: The function ``rte_event_eth_tx_adapter_enqueue`` takes an additional
386 input as ``flags``. Flag ``RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST`` which
387 has been introduced in this release is used when used when all the packets
388 enqueued in the tx adapter are destined for the same Ethernet port & Tx queue.
390 * sched: The pipe nodes configuration parameters such as number of pipes,
391 pipe queue sizes, pipe profiles, etc., are moved from port level structure
392 to subport level. This allows different subports of the same port to
393 have different configuration for the pipe nodes.
399 .. This section should contain ABI changes. Sample format:
401 * sample: Add a short 1-2 sentence description of the ABI change
402 which was announced in the previous releases and made in this release.
403 Start with a scope label like "ethdev:".
404 Use fixed width quotes for ``function_names`` or ``struct_names``.
407 This section is a comment. Do not overwrite or remove it.
408 Also, make sure to start the actual text at the margin.
409 =========================================================
411 * net: The Ethernet address and other header definitions have changed
412 attributes. They have been modified to be aligned on 2-byte boundaries.
413 These changes should not impact normal usage because drivers naturally
414 align the Ethernet header on receive and all known encapsulations
415 preserve the alignment of the header.
417 * security: The field ``replay_win_sz`` has been moved from ipsec library
418 based ``rte_ipsec_sa_prm`` structure to security library based structure
419 ``rte_security_ipsec_xform``, which specify the Anti replay window size
420 to enable sequence replay attack handling.
422 * ipsec: The field ``replay_win_sz`` has been removed from the structure
423 ``rte_ipsec_sa_prm`` as it has been added to the security library.
