150 .. This section should contain removed items in this release. Sample format:
152 * Add a short 1-2 sentence description of the removed item
155 This section is a comment. Do not overwrite or remove it.
156 Also, make sure to start the actual text at the margin.
157 =======================================================
159 * eal: Removed the deprecated function ``rte_get_master_lcore()``
160 and the iterator macro ``RTE_LCORE_FOREACH_SLAVE``.
162 * eal: The old api arguments that were deprecated for
163 blacklist/whitelist are removed. Users must use the new
164 block/allow list arguments.
166 * ethdev: Removed the port mirroring API. A more fine-grain flow API
167 action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` should be used instead.
168 The structures ``rte_eth_mirror_conf`` and ``rte_eth_vlan_mirror`` and
169 the functions ``rte_eth_mirror_rule_set`` and
170 ``rte_eth_mirror_rule_reset`` along with the associated macros
171 ``ETH_MIRROR_*`` are removed.
173 * i40e: Removed i40evf driver.
174 iavf already became the default VF driver for i40e devices,
175 so there is no need to maintain i40evf.
181 .. This section should contain API changes. Sample format:
183 * sample: Add a short 1-2 sentence description of the API change
184 which was announced in the previous releases and made in this release.
185 Start with a scope label like "ethdev:".
186 Use fixed width quotes for ``function_names`` or ``struct_names``.
189 This section is a comment. Do not overwrite or remove it.
190 Also, make sure to start the actual text at the margin.
191 =======================================================
193 * kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
194 removed. Its usages have been replaced by a new function
195 ``rte_kvargs_get_with_value()``.
197 * net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
198 to ``src_addr`` and ``dst_addr``, respectively.
200 * cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
201 rte_cryptodev_is_valid_dev as it can be used by the application as
202 well as PMD to check whether the device is valid or not.
204 * cryptodev: The rte_cryptodev_pmd.* files are renamed as cryptodev_pmd.*
205 as it is for drivers only and should be private to DPDK, and not
206 installed for app use.
208 * cryptodev: A ``reserved`` byte from structure ``rte_crypto_op`` was
209 renamed to ``aux_flags`` to indicate warnings and other information from
210 the crypto/security operation. This field will be used to communicate
211 events such as soft expiry with IPsec in lookaside mode.
217 .. This section should contain ABI changes. Sample format:
219 * sample: Add a short 1-2 sentence description of the ABI change
220 which was announced in the previous releases and made in this release.
221 Start with a scope label like "ethdev:".
222 Use fixed width quotes for ``function_names`` or ``struct_names``.
225 This section is a comment. Do not overwrite or remove it.
226 Also, make sure to start the actual text at the margin.
227 =======================================================
229 * security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
230 routines used by inline outbound and inline inbound security processing were
231 made inline and enhanced to do simple 64-bit set/get for PMDs that do not
232 have much processing in PMD specific callbacks but just 64-bit set/get.
233 This avoids a per packet function pointer jump overhead for such PMDs.
235 * security: A new option ``iv_gen_disable`` was added in structure
236 ``rte_security_ipsec_sa_options`` to disable IV generation inside PMD,
237 so that application can provide its own IV and test known test vectors.
239 * security: A new option ``tunnel_hdr_verify`` was added in structure
240 ``rte_security_ipsec_sa_options`` to indicate whether outer header
241 verification need to be done as part of inbound IPsec processing.
243 * security: A new option ``udp_ports_verify`` was added in structure
244 ``rte_security_ipsec_sa_options`` to indicate whether UDP ports
245 verification need to be done as part of inbound IPsec processing.
247 * security: A new structure ``rte_security_ipsec_lifetime`` was added to
248 replace ``esn_soft_limit`` in IPsec configuration structure
249 ``rte_security_ipsec_xform`` to allow applications to configure SA soft
250 and hard expiry limits. Limits can be either in number of packets or bytes.
252 * bbdev: Added capability related to more comprehensive CRC options,
253 shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
259 .. This section should contain new known issues in this release. Sample format:
261 * **Add title in present tense with full stop.**
263 Add a short 1-2 sentence description of the known issue
264 in the present tense. Add information on any known workarounds.
266 This section is a comment. Do not overwrite or remove it.
267 Also, make sure to start the actual text at the margin.
268 =======================================================
274 .. This section should contain a list of platforms that were tested
279 * <vendor> platform with <vendor> <type of devices> combinations
284 * Other relevant details...
