+Event device configuration for service based adapter
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When rte_event_timer_adapter_create() is used for creating
+adapter instance, ``rte_event_dev_config::nb_event_ports`` is
+automatically incremented, and the event device is reconfigured with
+additional event port during service initialization.
+This event device reconfigure logic also increments the
+``rte_event_dev_config::nb_single_link_event_port_queues``
+parameter if the adapter event port config is of type
+``RTE_EVENT_PORT_CFG_SINGLE_LINK``.
+
+Application no longer needs to account for the
+``rte_event_dev_config::nb_event_ports`` and
+``rte_event_dev_config::nb_single_link_event_port_queues``
+parameters required for timer adapter in event device configuration,
+when the adapter is created using the above-mentioned API.
+
 Adapter modes
 ^^^^^^^^^^^^^
 An event timer adapter can be configured in either periodic or non-periodic mode

      =======================================================
 
+* **Updated the eventdev reconfigure logic for service based adapters.**
+
+  * This eventdev reconfig logic is enhanced to increment the
+    ``rte_event_dev_config::nb_single_link_event_port_queues``
+    parameter if event port config is of type
+    ``RTE_EVENT_PORT_CFG_SINGLE_LINK``.
+  * With this change, the application no longer needs to account for the
+    ``rte_event_dev_config::nb_single_link_event_port_queues`` parameter
+    required for adapters.
+  * This change is added for eth_rx, eth_tx, crypto and timer eventdev adapters.
