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
