The lock-free stack implementation is enabled for aarch64 platforms.
+* **Extended pktmbuf mempool private structure.**
+
+ rte_pktmbuf_pool_private structure was extended to include flags field
+ for future compatibility.
+ As per 19.11 release this field is reserved and should be set to 0
+ by the user.
+
* **Changed mempool allocation behaviour.**
Objects are no longer across pages by default.
* **Added ethdev API to set supported packet types**
* Added new API ``rte_eth_dev_set_ptypes`` that allows an application to
- inform PMD about about reduced range of packet types to handle.
+ inform PMD about reduced range of packet types to handle.
* This scheme will allow PMDs to avoid lookup to internal ptype table on Rx
and thereby improve Rx performance if application wishes do so.
Added the new PFE driver for the NXP LS1012A platform. See the
:doc:`../nics/pfe` NIC driver guide for more details on this new driver.
+* **Updated Broadcom bnxt driver.**
+
+ Updated Broadcom bnxt driver with new features and improvements, including:
+
+ * Added support for hot firmware upgrade.
+ * Added support for error recovery.
+ * Added support for querying and using COS classification in hardware.
+ * Added LRO support Thor devices.
+ * Update HWRM API to version 1.10.1.6
+
* **Updated iavf PMD.**
Enable AVX2 data path for iavf PMD.
* Added support for matching on packets withe Geneve tunnel header.
* Added hairpin support.
* Added ConnectX6-DX support.
+ * Flow engine selected based on RDMA Core library version.
+ DV flow engine selected if version is rdma-core-24.0 or higher.
+ Verbs flow engine selected otherwise.
* **Updated the AF_XDP PMD.**
PDCP support is added to DPAA_SEC and DPAA2_SEC PMDs using rte_security APIs.
Support is added for all sequence number sizes for control and user plane.
- Test application is updated for unit testing.
+ Test and test-crypto-perf applications are updated for unit testing.
+
+* **Updated the AESNI-MB PMD.**
+
+ * Added support for intel-ipsec-mb version 0.53.
+
+* **Updated the AESNI-GCM PMD.**
+
+ * Added support for intel-ipsec-mb version 0.53.
+ * Supported in-place chained mbufs on AES-GCM algorithm.
* **Enabled Single Pass GCM acceleration on QAT GEN3.**
* Added a console command to testpmd app, ``show port (port_id) ptypes`` which
gives ability to print port supported ptypes in different protocol layers.
+ * Packet type detection disabled by default for the supported PMDs.
* **Added new example l2fwd-event application.**
See :doc:`../prog_guide/lto` for more information:
+* **Added IOVA as VA support for KNI.**
+
+ * Added IOVA = VA support for KNI, KNI can operate in IOVA = VA mode when
+ `iova-mode=va` EAL option is passed to the application or when bus IOVA
+ scheme is selected as RTE_IOVA_VA. This mode only works on Linux Kernel
+ versions above 4.9.0.
+
+ * Due to IOVA to KVA address translations, based on the KNI use case there
+ can be a performance impact. For mitigation, forcing IOVA to PA via EAL
+ "--iova-mode=pa" option can be used, IOVA_DC bus iommu scheme can also
+ result in IOVA as PA.
Removed Items
Also, make sure to start the actual text at the margin.
=========================================================
+* Removed library-level ABI versions. These have been replaced with a single
+ project-level ABI version for non-experimental libraries and an ABI version of
+ ``0`` for experimental libraries. Review the :doc:`../contributing/abi_policy`
+ and :doc:`../contributing/abi_versioning` guides for more information.
+
* Removed duplicated set of commands for Rx offload configuration from testpmd::
port config all crc-strip|scatter|rx-cksum|rx-timestamp|
Also, make sure to start the actual text at the margin.
=========================================================
+* policy: Please note the revisions to the :doc:`../contributing/abi_policy`
+ introducing major ABI versions, with DPDK 19.11 becoming the first major
+ version ``v20``. ABI changes to add new features continue to be permitted in
+ subsequent releases, with the condition that ABI compatibility with the major
+ ABI version is maintained.
+
* net: The Ethernet address and other header definitions have changed
attributes. They have been modified to be aligned on 2-byte boundaries.
These changes should not impact normal usage because drivers naturally
* ipsec: The field ``replay_win_sz`` has been removed from the structure
``rte_ipsec_sa_prm`` as it has been added to the security library.
+* ethdev: Added 32-bit fields for maximum LRO aggregated packet size, in
+ struct ``rte_eth_dev_info`` for the port capability and in struct
+ ``rte_eth_rxmode`` for the port configuration.
+ Application should use the new field in struct ``rte_eth_rxmode`` to configure
+ the requested size.
+ PMD should use the new field in struct ``rte_eth_dev_info`` to report the
+ supported port capability.
