-* ethdev: Some internal APIs for driver usage are exported in the .map file.
- Now DPDK has ``__rte_internal`` marker so we can mark internal APIs and move
- them to the INTERNAL block in .map. Although these APIs are internal it will
- break the ABI checks, that is why change is planned for 20.11.
- The list of internal APIs are mainly ones listed in ``rte_ethdev_driver.h``.
-
-* traffic manager: All traffic manager API's in ``rte_tm.h`` were mistakenly made
- ABI stable in the v19.11 release. The TM maintainer and other contributors have
- agreed to keep the TM APIs as experimental in expectation of additional spec
- improvements. Therefore, all APIs in ``rte_tm.h`` will be marked back as
- experimental in v20.11 DPDK release. For more details, please see `the thread
- <https://mails.dpdk.org/archives/dev/2020-April/164970.html>`_.
-
-* pmd_dpaa: The API ``rte_pmd_dpaa_set_tx_loopback`` will have extended
- ``port_id`` definition from ``uint8_t`` to ``uint16_t``.
-
-* cryptodev: support for using IV with all sizes is added, J0 still can
- be used but only when IV length in following structs ``rte_crypto_auth_xform``,
- ``rte_crypto_aead_xform`` is set to zero. When IV length is greater or equal
- to one it means it represents IV, when is set to zero it means J0 is used
- directly, in this case 16 bytes of J0 need to be passed.
-
-* rawdev: The rawdev APIs which take a device-specific structure as
- parameter directly, or indirectly via a "private" pointer inside another
- structure, will be modified to take an additional parameter of the
- structure size. The affected APIs will include ``rte_rawdev_info_get``,
- ``rte_rawdev_configure``, ``rte_rawdev_queue_conf_get`` and
- ``rte_rawdev_queue_setup``.
+* ethdev: The port mirroring API can be replaced with a more fine grain flow API.
+ The structs ``rte_eth_mirror_conf``, ``rte_eth_vlan_mirror`` and the functions
+ ``rte_eth_mirror_rule_set``, ``rte_eth_mirror_rule_reset`` will be marked
+ as deprecated in DPDK 20.11, along with the associated macros ``ETH_MIRROR_*``.
+ This API will be fully removed in DPDK 21.11.
+
+* ethdev: Attribute ``shared`` of the ``struct rte_flow_action_count``
+ is deprecated and will be removed in DPDK 21.11. Shared counters should
+ be managed using shared actions API (``rte_flow_shared_action_create`` etc).
+
+* ethdev: The flow API matching pattern structures, ``struct rte_flow_item_*``,
+ should start with relevant protocol header.
+ Some matching pattern structures implements this by duplicating protocol header
+ fields in the struct. To clarify the intention and to be sure protocol header
+ is intact, will replace those fields with relevant protocol header struct.
+ In v21.02 both individual protocol header fields and the protocol header struct
+ will be added as union, target is switch usage to the protocol header by time.
+ In v21.11 LTS, protocol header fields will be cleaned and only protocol header
+ struct will remain.
+
+* ethdev: Queue specific stats fields will be removed from ``struct rte_eth_stats``.
+ Mentioned fields are: ``q_ipackets``, ``q_opackets``, ``q_ibytes``, ``q_obytes``,
+ ``q_errors``.
+ Instead queue stats will be received via xstats API. Current method support
+ will be limited to maximum 256 queues.
+ Also compile time flag ``RTE_ETHDEV_QUEUE_STAT_CNTRS`` will be removed.
+
+* ethdev: The offload flag ``PKT_RX_EIP_CKSUM_BAD`` will be removed and
+ replaced by the new flag ``PKT_RX_OUTER_IP_CKSUM_BAD``. The new name is more
+ consistent with existing outer header checksum status flag naming, which
+ should help in reducing confusion about its usage.
+
+* i40e: As there are both i40evf and iavf pmd, the functions of them are
+ duplicated. And now more and more advanced features are developed on iavf.
+ To keep consistent with kernel driver's name
+ (https://patchwork.ozlabs.org/patch/970154/), i40evf is no need to maintain.
+ Starting from 21.05, the default VF driver of i40e will be iavf, but i40evf
+ can still be used if users specify the devarg "driver=i40evf". I40evf will
+ be deleted in DPDK 21.11.
+
+* eventdev: The structure ``rte_event_eth_rx_adapter_queue_conf`` will be
+ extended to include ``rte_event_eth_rx_adapter_event_vector_config`` elements
+ and the function ``rte_event_eth_rx_adapter_queue_event_vector_config`` will
+ be removed in DPDK 21.11.
+
+ An application can enable event vectorization by passing the desired vector
+ values to the function ``rte_event_eth_rx_adapter_queue_add`` using
+ the structure ``rte_event_eth_rx_adapter_queue_add``.
