185 This section is a comment. Do not overwrite or remove it.
186 Also, make sure to start the actual text at the margin.
187 =======================================================
189 * eal: Removed the deprecated function ``rte_get_master_lcore()``
190 and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``.
192 * eal: The old api arguments that were deprecated for
193 blacklist/whitelist are removed. Users must use the new
194 block/allow list arguments.
196 * mbuf: Removed offload flag ``PKT_RX_EIP_CKSUM_BAD``.
197 ``PKT_RX_OUTER_IP_CKSUM_BAD`` should be used as a replacement.
199 * ethdev: Removed the port mirroring API. A more fine-grain flow API
200 action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` should be used instead.
201 The structures ``rte_eth_mirror_conf`` and ``rte_eth_vlan_mirror`` and
202 the functions ``rte_eth_mirror_rule_set`` and
203 ``rte_eth_mirror_rule_reset`` along with the associated macros
204 ``ETH_MIRROR_*`` are removed.
206 * i40e: Removed i40evf driver.
207 iavf already became the default VF driver for i40e devices,
208 so there is no need to maintain i40evf.
214 .. This section should contain API changes. Sample format:
216 * sample: Add a short 1-2 sentence description of the API change
217 which was announced in the previous releases and made in this release.
218 Start with a scope label like "ethdev:".
219 Use fixed width quotes for ``function_names`` or ``struct_names``.
222 This section is a comment. Do not overwrite or remove it.
223 Also, make sure to start the actual text at the margin.
224 =======================================================
226 * kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
227 removed. Its usages have been replaced by a new function
228 ``rte_kvargs_get_with_value()``.
230 * mempool: Added ``RTE_MEMPOOL_F_NON_IO`` flag to give a hint to DPDK components
231 that objects from this pool will not be used for device IO (e.g. DMA).
233 * mempool: The mempool flags ``MEMPOOL_F_*`` will be deprecated in the future.
234 Newly added flags with ``RTE_MEMPOOL_F_`` prefix should be used instead.
236 * mempool: Helper macro ``MEMPOOL_HEADER_SIZE()`` is deprecated.
237 The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
239 * mempool: Macro to register mempool driver ``MEMPOOL_REGISTER_OPS()`` is
240 deprecated. Use replacement ``RTE_MEMPOOL_REGISTER_OPS()``.
242 * mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
243 will be removed in DPDK 22.11.
245 * net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
246 to ``src_addr`` and ``dst_addr``, respectively.
248 * cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
249 rte_cryptodev_is_valid_dev as it can be used by the application as
250 well as PMD to check whether the device is valid or not.
252 * cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.*
253 as it is for drivers only and should be private to DPDK, and not
254 installed for app use.
256 * cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was
257 renamed to ``aux_flags`` to indicate warnings and other information from
258 the crypto/security operation. This field will be used to communicate
259 events such as soft expiry with IPsec in lookaside mode.
261 * cryptodev: The field ``dataunit_len`` of the ``struct rte_crypto_cipher_xform``
262 moved to the end of the structure and extended to ``uint32_t``.
268 .. This section should contain ABI changes. Sample format:
270 * sample: Add a short 1-2 sentence description of the ABI change
271 which was announced in the previous releases and made in this release.
272 Start with a scope label like "ethdev:".
273 Use fixed width quotes for ``function_names`` or ``struct_names``.
276 This section is a comment. Do not overwrite or remove it.
277 Also, make sure to start the actual text at the margin.
278 =======================================================
280 * security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
281 routines used by inline outbound and inline inbound security processing were
282 made inline and enhanced to do simple 64-bit set/get for PMDs that do not
283 have much processing in PMD specific callbacks but just 64-bit set/get.
284 This avoids a per packet function pointer jump overhead for such PMDs.
286 * security: A new option ``iv_gen_disable`` was added in structure
287 ``rte_security_ipsec_sa_options`` to disable IV generation inside PMD,
288 so that application can provide its own IV and test known test vectors.
290 * security: A new option ``tunnel_hdr_verify`` was added in structure
291 ``rte_security_ipsec_sa_options`` to indicate whether outer header
292 verification need to be done as part of inbound IPsec processing.
294 * security: A new option ``udp_ports_verify`` was added in structure
295 ``rte_security_ipsec_sa_options`` to indicate whether UDP ports
296 verification need to be done as part of inbound IPsec processing.
298 * security: A new structure ``rte_security_ipsec_lifetime`` was added to
299 replace ``esn_soft_limit`` in IPsec configuration structure
300 ``rte_security_ipsec_xform`` to allow applications to configure SA soft
301 and hard expiry limits. Limits can be either in number of packets or bytes.
303 * security: The new options ``ip_csum_enable`` and ``l4_csum_enable`` were added
304 in structure ``rte_security_ipsec_sa_options`` to indicate whether inner
305 packet IPv4 header checksum and L4 checksum need to be offloaded to
308 * security: A new structure ``esn`` was added in structure
309 ``rte_security_ipsec_xform`` to set an initial ESN value. This permits
310 application to start from an arbitrary ESN value for debug and SA lifetime
311 enforcement purposes.
313 * bbdev: Added capability related to more comprehensive CRC options,
314 shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
320 .. This section should contain new known issues in this release. Sample format:
322 * **Add title in present tense with full stop.**
324 Add a short 1-2 sentence description of the known issue
325 in the present tense. Add information on any known workarounds.
