80 any arbitrary header field (as well as mark, metadata or tag values):
81 ``RTE_FLOW_ACTION_TYPE_MODIFY_FIELD``.

124 egress flow groups greater than 0 and for any transfer flow group.
125 * Added support for the Tx mbuf fast free offload.

155 for every enqueue/dequeue operation.

169 Added a new compress PMD driver for Bluefield 2 adapters.
171 See the :doc:`../compressdevs/mlx5` for more details.
173 * **Added support for build-time checking of header includes.**
175 A new build option ``check_includes`` has been added, which, when enabled,
176 will perform build-time checking on DPDK public header files, to ensure none
177 are missing dependent header includes. This feature, disabled by default, is
178 intended for use by developers contributing to the DPDK SDK itself, and is
179 integrated into the build scripts and automated CI for patch contributions.

192 =======================================================
194 * The internal header files ``rte_ethdev_driver.h``, ``rte_ethdev_vdev.h`` and
195 ``rte_ethdev_pci.h`` are no longer installed as part of the DPDK
196 ``ninja install`` action and are renamed to ``ethdev_driver.h``,
197 ``ethdev_vdev.h`` and ``ethdev_pci.h`` respectively in the source tree, to
198 reflect the fact that they are non-public headers.
200 * The internal header files ``rte_eventdev_pmd.h``, ``rte_eventdev_pmd_vdev.h``
201 and ``rte_eventdev_pmd_pci.h`` are no longer installed as part of the DPDK
202 ``ninja install`` action and are renamed to ``eventdev_pmd.h``,
203 ``eventdev_pmd_vdev.h`` and ``eventdev_pmd_pci.h`` respectively in the source
204 tree, to reflect the fact that they are non-public headers.
206 * Removed support for NetXtreme devices belonging to ``BCM573xx and
207 BCM5740x`` families. Specifically the support for the following Broadcom
208 PCI device IDs ``0x16c8, 0x16c9, 0x16ca, 0x16ce, 0x16cf, 0x16df, 0x16d0,``
209 ``0x16d1, 0x16d2, 0x16d4, 0x16d5, 0x16e7, 0x16e8, 0x16e9`` has been removed.
211 * The ``check-includes.sh`` script for checking DPDK header files has been
212 removed, being replaced by the ``check_includes`` build option described

232 to indicate which DPDK libraries and drivers are built.
233 The new macros are generated by meson in a standardized format:
234 ``RTE_LIB_<NAME>`` and ``RTE_<CLASS>_<NAME>``, where ``NAME`` is
235 the upper-case component name, e.g. ``EAL``, ``ETHDEV``, ``VIRTIO``,
236 and ``CLASS`` is the upper-case driver class, e.g. ``NET``, ``CRYPTO``.
238 * cryptodev: The structure ``rte_cryptodev`` has been updated with pointers
239 for adding enqueue and dequeue callbacks.
