158 .. This section should contain removed items in this release. Sample format:
160 * Add a short 1-2 sentence description of the removed item
163 This section is a comment. Do not overwrite or remove it.
164 Also, make sure to start the actual text at the margin.
165 =======================================================
167 * eal: Removed the deprecated function ``rte_get_master_lcore()``
168 and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``.
170 * eal: The old api arguments that were deprecated for
171 blacklist/whitelist are removed. Users must use the new
172 block/allow list arguments.
174 * ethdev: Removed the port mirroring API. A more fine-grain flow API
175 action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` should be used instead.
176 The structures ``rte_eth_mirror_conf`` and ``rte_eth_vlan_mirror`` and
177 the functions ``rte_eth_mirror_rule_set`` and
178 ``rte_eth_mirror_rule_reset`` along with the associated macros
179 ``ETH_MIRROR_*`` are removed.
181 * i40e: Removed i40evf driver.
182 iavf already became the default VF driver for i40e devices,
183 so there is no need to maintain i40evf.
189 .. This section should contain API changes. Sample format:
191 * sample: Add a short 1-2 sentence description of the API change
192 which was announced in the previous releases and made in this release.
193 Start with a scope label like "ethdev:".
194 Use fixed width quotes for ``function_names`` or ``struct_names``.
197 This section is a comment. Do not overwrite or remove it.
198 Also, make sure to start the actual text at the margin.
199 =======================================================
201 * kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
202 removed. Its usages have been replaced by a new function
203 ``rte_kvargs_get_with_value()``.
205 * net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
206 to ``src_addr`` and ``dst_addr``, respectively.
208 * cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
209 rte_cryptodev_is_valid_dev as it can be used by the application as
210 well as PMD to check whether the device is valid or not.
212 * cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.*
213 as it is for drivers only and should be private to DPDK, and not
214 installed for app use.
216 * cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was
217 renamed to ``aux_flags`` to indicate warnings and other information from
218 the crypto/security operation. This field will be used to communicate
219 events such as soft expiry with IPsec in lookaside mode.
225 .. This section should contain ABI changes. Sample format:
227 * sample: Add a short 1-2 sentence description of the ABI change
228 which was announced in the previous releases and made in this release.
229 Start with a scope label like "ethdev:".
230 Use fixed width quotes for ``function_names`` or ``struct_names``.
233 This section is a comment. Do not overwrite or remove it.
234 Also, make sure to start the actual text at the margin.
235 =======================================================
237 * security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
238 routines used by inline outbound and inline inbound security processing were
239 made inline and enhanced to do simple 64-bit set/get for PMDs that do not
240 have much processing in PMD specific callbacks but just 64-bit set/get.
241 This avoids a per packet function pointer jump overhead for such PMDs.
243 * security: A new option ``iv_gen_disable`` was added in structure
244 ``rte_security_ipsec_sa_options`` to disable IV generation inside PMD,
245 so that application can provide its own IV and test known test vectors.
247 * security: A new option ``tunnel_hdr_verify`` was added in structure
248 ``rte_security_ipsec_sa_options`` to indicate whether outer header
249 verification need to be done as part of inbound IPsec processing.
251 * security: A new option ``udp_ports_verify`` was added in structure
252 ``rte_security_ipsec_sa_options`` to indicate whether UDP ports
253 verification need to be done as part of inbound IPsec processing.
255 * security: A new structure ``rte_security_ipsec_lifetime`` was added to
256 replace ``esn_soft_limit`` in IPsec configuration structure
257 ``rte_security_ipsec_xform`` to allow applications to configure SA soft
258 and hard expiry limits. Limits can be either in number of packets or bytes.
260 * bbdev: Added capability related to more comprehensive CRC options,
261 shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
267 .. This section should contain new known issues in this release. Sample format:
269 * **Add title in present tense with full stop.**
271 Add a short 1-2 sentence description of the known issue
272 in the present tense. Add information on any known workarounds.
274 This section is a comment. Do not overwrite or remove it.
275 Also, make sure to start the actual text at the margin.
276 =======================================================
282 .. This section should contain a list of platforms that were tested
287 * <vendor> platform with <vendor> <type of devices> combinations
292 * Other relevant details...
