 * cmdline: ``cmdline`` structure will be made opaque to hide platform-specific
   content. On Linux and FreeBSD, supported prior to DPDK 20.11,
   original structure will be kept until 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``.
