which allow the programmer to prefetch a cache line and also indicate
the intention to write.
+* **Added the rte_cldemote API.**
+
+ Added a hardware hint CLDEMOTE, which is similar to prefetch in reverse.
+ CLDEMOTE moves the cache line to the more remote cache, where it expects
+ sharing to be efficient. Moving the cache line to a level more distant from
+ the processor helps to accelerate core-to-core communication.
+ This API is specific to x86 and implemented as a stub for other
+ architectures.
+
* **Updated CRC modules of the net library.**
* Added runtime selection of the optimal architecture-specific CRC path.
Added the FEC API which provides functions for query FEC capabilities and
current FEC mode from device. Also, API for configuring FEC mode is also provided.
+* **Added thread safety to rte_flow functions.**
+
+ Added ``RTE_ETH_DEV_FLOW_OPS_THREAD_SAFE`` device flag to indicate
+ whether PMD supports thread safe operations. If PMD doesn't set the flag,
+ rte_flow API level functions will protect the flow operations with mutex.
+
+* **Added flow-based traffic sampling support.**
+
+ Added new action: ``RTE_FLOW_ACTION_TYPE_SAMPLE`` to duplicate the matching
+ packets with specified ratio, and apply with own set of actions with a fate
+ action. When the ratio is set to 1 then the packets will be 100% mirrored.
+
* **Updated Broadcom bnxt driver.**
Updated the Broadcom bnxt driver with new features and improvements, including:
* Added support for 200G PAM4 link speed.
* Added support for RSS hash level selection.
* Updated HWRM structures to 1.10.1.70 version.
+ * Added TRUFLOW support for Stingray devices.
* **Updated Cisco enic driver.**
Updated the Intel qat driver to use write combining stores.
+* **Updated Memif PMD.**
+
+ * Added support for abstract socket address.
+ * Changed default socket address type to abstract.
+
* **Added Ice Lake (Gen4) support for Intel NTB.**
Added NTB device support (4th generation) for Intel Ice Lake platform.
* Added flag action.
* Added raw encap/decap actions.
* Added VXLAN encap/decap actions.
- * Added ICMP and ICMP6 matching items.
+ * Added ICMP(code/type/identifier/sequence number) and ICMP6(code/type) matching items.
* Added option to set port mask for insertion/deletion:
``--portmask=N``
where N represents the hexadecimal bitmask of ports used.
See the :doc:`../regexdevs/octeontx2` for more details.
+* **Updated Software Eventdev driver.**
+
+ Added performance tuning arguments to allow tuning the scheduler for
+ better throughtput in high core count use cases.
+
* **Updated ioat rawdev driver**
The ioat rawdev driver has been updated and enhanced. Changes include:
* ethdev: ``rte_eth_rx_descriptor_done()`` API has been deprecated.
-* Renamed internal ethdev APIs:
+* ethdev: Renamed basic statistics per queue. An underscore is inserted
+ between the queue number and the rest of the xstat name:
+
+ * ``rx_qN*`` -> ``rx_qN_*``
+ * ``tx_qN*`` -> ``tx_qN_*``
+
+* ethdev: Added capability to query age flow action.
+
+* ethdev: Renamed internal functions:
* ``_rte_eth_dev_callback_process()`` -> ``rte_eth_dev_callback_process()``
* ``_rte_eth_dev_reset`` -> ``rte_eth_dev_internal_reset()``
* vhost: Moved vDPA APIs from experimental to stable.
+* vhost: Add a new function ``rte_vhost_crypto_driver_start`` to be called
+ instead of ``rte_vhost_driver_start`` by crypto applications.
+
* cryptodev: The structure ``rte_crypto_sym_vec`` is updated to support both
cpu_crypto synchrounous operation and asynchronous raw data-path APIs.
* ``ethdev`` internal functions are marked with ``__rte_internal`` tag.
+* eventdev: Following structures are modified to support DLB/DLB2 PMDs
+ and future extensions:
+
+ * ``rte_event_dev_info``
+ * ``rte_event_dev_config``
+ * ``rte_event_port_conf``
+
* sched: Added new fields to ``struct rte_sched_subport_port_params``.
