 Deprecation Notices
 -------------------
 
-* build: The macros defined to indicate which DPDK libraries and drivers
-  are included in the meson build are changing to a standardized format of
-  ``RTE_LIB_<NAME>`` and ``RTE_<CLASS>_<NAME>``, where ``NAME`` is the
-  upper-case component name, e.g. EAL, ETHDEV, IXGBE, and ``CLASS`` is the
-  upper-case name of the device class to which a driver belongs e.g.
-  ``NET``, ``CRYPTO``, ``VDPA``. The old macros are deprecated and will be
-  removed in a future release.
-
 * kvargs: The function ``rte_kvargs_process`` will get a new parameter
   for returning key match count. It will ease handling of no-match case.

   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``.
+
 * sched: To allow more traffic classes, flexible mapping of pipe queues to
   traffic classes, and subport level configuration of pipes and queues
   changes will be made to macros, data structures and API functions defined
