``rte_eth_mirror_rule_reset`` along with the associated macros
``ETH_MIRROR_*`` are removed.
+* ethdev: Removed ``rte_eth_rx_descriptor_done`` API function and its
+ driver callback. It is replaced by the more complete function
+ ``rte_eth_rx_descriptor_status``.
+
+* ethdev: Removed deprecated ``shared`` attribute of the
+ ``struct rte_flow_action_count``. Shared counters should be managed
+ using indirect actions API (``rte_flow_action_handle_create`` etc).
+
* i40e: Removed i40evf driver.
iavf already became the default VF driver for i40e devices,
so there is no need to maintain i40evf.
removed. Its usages have been replaced by a new function
``rte_kvargs_get_with_value()``.
+* 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).
+
+* mempool: The mempool flags ``MEMPOOL_F_*`` will be deprecated in the future.
+ Newly added flags with ``RTE_MEMPOOL_F_`` prefix should be used instead.
+
+* mempool: Helper macro ``MEMPOOL_HEADER_SIZE()`` is deprecated.
+ The replacement macro ``RTE_MEMPOOL_HEADER_SIZE()`` is internal only.
+
+* mempool: Macro to register mempool driver ``MEMPOOL_REGISTER_OPS()`` is
+ deprecated. Use replacement ``RTE_MEMPOOL_REGISTER_OPS()``.
+
+* mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
+ will be removed in DPDK 22.11.
+
* net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
to ``src_addr`` and ``dst_addr``, respectively.

+ ``PORT_REPRESENTOR`` to flow API.
+
* cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
rte_cryptodev_is_valid_dev as it can be used by the application as
well as PMD to check whether the device is valid or not.
the crypto/security operation. This field will be used to communicate
events such as soft expiry with IPsec in lookaside mode.
+* cryptodev: The field ``dataunit_len`` of the ``struct rte_crypto_cipher_xform``
+ moved to the end of the structure and extended to ``uint32_t``.
+
+* cryptodev: The structure ``rte_crypto_vec`` was updated to add ``tot_len``
+ field to support total buffer length to facilitate protocol offload case.
+
+* cryptodev: The structure ``rte_crypto_sym_vec`` was updated to add
+ ``dest_sgl`` to support out of place processing.
+
+* bbdev: Added device info related to data byte endianness processing.

ABI Changes
-----------
Also, make sure to start the actual text at the margin.
=======================================================
+* ethdev: Input parameters for ``eth_rx_queue_count_t`` was changed.
+ Instead of pointer to ``rte_eth_dev`` and queue index, now it accepts pointer
+ to internal queue data as input parameter. While this change is transparent
+ to user, it still counts as an ABI change, as ``eth_rx_queue_count_t``
+ is used by public inline function ``rte_eth_rx_queue_count``.
+
+* ethdev: Made ``rte_eth_dev``, ``rte_eth_dev_data``, ``rte_eth_rxtx_callback``
+ private data structures. ``rte_eth_devices[]`` can't be accessed directly
+ by user any more. While it is an ABI breakage, this change is intended
+ to be transparent for both users (no changes in user app is required) and
+ PMD developers (no changes in PMD is required).
+
* security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
routines used by inline outbound and inline inbound security processing were
made inline and enhanced to do simple 64-bit set/get for PMDs that do not
packet IPv4 header checksum and L4 checksum need to be offloaded to
security device.
+* security: A new structure ``esn`` was added in structure
+ ``rte_security_ipsec_xform`` to set an initial ESN value. This permits
+ application to start from an arbitrary ESN value for debug and SA lifetime
+ enforcement purposes.
+
+* security: A new structure ``udp`` was added in structure
+ ``rte_security_ipsec_xform`` to allow setting the source and destination ports
+ for UDP encapsulated IPsec traffic.
+
* bbdev: Added capability related to more comprehensive CRC options,
shifting values of the ``enum rte_bbdev_op_ldpcdec_flag_bitmasks``.
