operations.
* Added multi-process support.
+* **Added IDXD dmadev driver implementation.**
+
+ The IDXD dmadev driver provide device drivers for the Intel DSA devices.
+ This device driver can be used through the generic dmadev API.
+
+* **Added IOAT dmadev driver implementation.**
+
+ The Intel I/O Acceleration Technology (IOAT) dmadev driver provides a device
+ driver for Intel IOAT devices such as Crystal Beach DMA (CBDMA) on Ice Lake,
+ Skylake and Broadwell. This device driver can be used through the generic dmadev API.
+
* **Added support to get all MAC addresses of a device.**
Added ``rte_eth_macaddrs_get`` to allow user to retrieve all Ethernet
Added macros ETH_RSS_IPV4_CHKSUM and ETH_RSS_L4_CHKSUM, now IPv4 and
TCP/UDP/SCTP header checksum field can be used as input set for RSS.
+* **Added L2TPv2 and PPP protocol support in flow API.**
+
+ Added flow pattern items and header formats of L2TPv2 and PPP protocol.
+
+* **Added flow flex item.**
+
+ The configurable flow flex item provides the capability to introduce
+ an arbitrary user-specified network protocol header,
+ configure the hardware accordingly, and perform match on this header
+ with desired patterns and masks.
+
* **Added ethdev support to control delivery of Rx metadata from the HW to the PMD.**
A new API, ``rte_eth_rx_metadata_negotiate()``, was added.
* Support for the tx_free_thresh and rx_free_thresh configuration parameters.
* NUMA aware allocations for the queue helper structures.
+ * Watchdog's feature which is checking for missing Tx completions.
* **Updated Broadcom bnxt PMD.**
* Added Intel iavf support on Windows.
* Added IPv4 and L4 (TCP/UDP/SCTP) checksum hash support in RSS flow.
+ * Added PPPoL2TPv2oUDP RSS hash based on inner IP address and TCP/UDP port.
* **Updated Intel ice driver.**
* Added rte_tm support.
* Added support for Inline IPsec for CN9K event mode and CN10K
poll mode and event mode.
+ * Added support for ingress meter for CN10K platform.
* **Updated Mellanox mlx5 driver.**
* Added tests to verify tunnel header verification in IPsec inbound.
* Added tests to verify inner checksum.
+* **Revised packet capture framework.**
+
+ * New dpdk-dumpcap program that has most of the features
+ of the wireshark dumpcap utility including:
+ capture of multiple interfaces, filtering,
+ and stopping after number of bytes, packets.
+ * New library for writing pcapng packet capture files.
+ * Enhancements to the pdump library to support:
+ * Packet filter with BPF.
+ * Pcapng format with timestamps and meta-data.
+ * Fixes packet capture with stripped VLAN tags.

Removed Items
-------------
removed. Its usages have been replaced by a new function
``rte_kvargs_get_with_value()``.
+* cmdline: ``cmdline_stdin_exit()`` now frees the ``cmdline`` structure.
+ Calls to ``cmdline_free()`` after it need to be deleted from applications.
+
+* cmdline: Made ``cmdline`` structure definition hidden on Linux and FreeBSD.
+
+* cmdline: Made ``rdline`` structure definition hidden. Functions are added
+ to dynamically allocate and free it, and to access user data in callbacks.
+
* mempool: Added ``RTE_MEMPOOL_F_NON_IO`` flag to give a hint to DPDK components
that objects from this pool will not be used for device IO (e.g. DMA).
* bbdev: Added device info related to data byte endianness processing.
+* eventdev: Moved memory used by timer adapters to hugepage. This will prevent
+ TLB misses if any and aligns to memory structure of other subsystems.
+
ABI Changes
-----------
* bbdev: Added capability related to more comprehensive CRC options,
shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
+* eventdev: New variables ``rx_event_buf_count`` and ``rx_event_buf_size``
+ were added in structure ``rte_event_eth_rx_adapter_stats`` to get additional
+ status.
+
+* eventdev: A new structure ``rte_event_fp_ops`` has been added which is now used
+ by the fastpath inline functions. The structures ``rte_eventdev``,
+ ``rte_eventdev_data`` have been made internal. ``rte_eventdevs[]`` can't be
+ accessed directly by user any more. This change is transparent to both
+ applications and PMDs.
+
+* eventdev: Re-arranged fields in ``rte_event_timer`` to remove holes.
