=========================================================
+* **Added MCS lock.**
+
+ MCS lock provides scalability by spinning on a CPU/thread local variable
+ which avoids expensive cache bouncings.
+ It provides fairness by maintaining a list of acquirers and passing
+ the lock to each CPU/thread in the order they acquired the lock.
+
* **Updated the EAL Pseudo-random Number Generator.**
The lrand48()-based rte_rand() function is replaced with a
* Enabled generic filter framework and supported switch filter.
* Supported UDP tunnel port add.
+* **Updated Mellanox mlx5 driver.**
+
+ Updated Mellanox mlx5 driver with new features and improvements, including:
+
+ * Updated the packet header modification feature. Added support of TCP header
+ sequence number and acknowledgment number modification.
+ * Added support for match on ICMP/ICMP6 code and type.
+
* **Updated Solarflare network PMD.**
Updated the Solarflare ``sfc_efx`` driver with changes including:
* Enabled need_wakeup feature which can provide efficient support for case
that application and driver executing on the same core.
+* **Enabled infinite Rx in the PCAP PMD.**
+
+ Added an infinite Rx feature which allows packets in the Rx PCAP of a PCAP
+ device to be received repeatedly at a high rate. This can be useful for quick
+ performance testing of DPDK apps.
+
+* **Added a FPGA_LTE_FEC bbdev PMD.**
+
+ Added the new ``fpga_lte_fec`` bbdev driver for the IntelĀ® FPGA PAC
+ (Programmable Acceleration Card) N3000. See the
+ :doc:`../bbdevs/fpga_lte_fec` BBDEV guide for more details on this new driver.
+
+* **Updated TURBO_SW bbdev PMD.**
+
+ Updated the ``turbo_sw`` bbdev driver with changes including:
+
+ * Added option to build the driver with or without dependency of external
+ SDK libraries.
+ * Added support for 5GNR encode/decode operations.
+
+* **Updated the QuickAssist Technology (QAT) symmetric crypto PMD.**
+
+ Added support for digest-encrypted cases where digest is appended
+ to the data.
+
* **Added Intel QuickData Technology PMD**
The PMD for Intel\ |reg| QuickData Technology, part of
of via software, reducing cycles spent copying large blocks of data in
applications.
+* **Added Marvell OCTEON TX2 drivers.**
+
+ Added the new ``ethdev``, ``eventdev``, ``mempool``, ``eventdev Rx adapter``,
+ ``eventdev Tx adapter``, ``eventdev Timer adapter`` and ``rawdev DMA``
+ drivers for various HW coprocessors available in ``OCTEON TX2`` SoC.
+
+ See :doc:`../platform/octeontx2` and driver informations:
+
+ * :doc:`../nics/octeontx2`
+ * :doc:`../mempool/octeontx2`
+ * :doc:`../eventdevs/octeontx2`
+ * :doc:`../rawdevs/octeontx2_dma`
+
* **Introduced NTB PMD.**
Added a PMD for Intel NTB (Non-transparent Bridge). This PMD implemented
handshake between two separate hosts and can share local memory for peer
host to directly access.
+* **Updated IPSec library Header Reconstruction.**
+
+ Updated the IPSec library with ECN and DSCP field header reconstruction
+ feature followed by RFC4301. The IPSec-secgw sample application is also
+ updated to support this feature by default.
+
* **Updated telemetry library for global metrics support.**
Updated ``librte_telemetry`` to fetch the global metrics from the
Added telemetry mode to l3fwd-power application to report
application level busyness, empty and full polls of rte_eth_rx_burst().
+* **Updated the pdump application.**
+
+ Add support for pdump to exit with primary process.
+
Removed Items

=========================================================
+* The ``rte_mem_config`` structure has been made private. The new accessor
+ ``rte_mcfg_*`` functions were introduced to provide replacement for direct
+ access to the shared mem config.
+
* The network structures, definitions and functions have
been prefixed by ``rte_`` to resolve conflicts with libc headers.
announced at least one release before the ABI change is made. There are no
ABI breaking changes planned.
+* ip_frag: IP fragmentation library converts input mbuf into fragments
+ using input MTU size via ``rte_ipv4_fragment_packet`` interface.
+ Once fragmentation is done, each ``mbuf->ol_flags`` are set to enable IP
+ checksum H/W offload irrespective of the platform capability.
+ Cleared IP checksum H/W offload flag from the library. The application must
+ set this flag if it is supported by the platform and application wishes to
+ use it.
+
+* ip_frag: IP reassembly library converts the list of fragments into a
+ reassembled packet via ``rte_ipv4_frag_reassemble_packet`` interface.
+ Once reassembly is done, ``mbuf->ol_flags`` are set to enable IP checksum H/W
+ offload irrespective of the platform capability. Cleared IP checksum H/W
+ offload flag from the library. The application must set this flag if it is
+ supported by the platform and application wishes to use it.
+
ABI Changes
-----------
Add a Rx adapter stats field to keep track of the total
number of dropped packets.
+* cryptodev: New member in ``rte_cryptodev_config`` to allow applications to
+ disable features supported by the crypto device. Only the following features
+ would be allowed to be disabled this way,
+
+ - ``RTE_CRYPTODEV_FF_SYMMETRIC_CRYPTO``
+ - ``RTE_CRYPTODEV_FF_ASYMMETRIC_CRYPTO``
+ - ``RTE_CRYPTODEV_FF_SECURITY``
+
+ Disabling unused features would facilitate efficient usage of HW/SW offload.
+
+* bbdev: New operations and parameters added to support new 5GNR operations.
+ The bbdev ABI is still kept experimental.
