When rte_event_crypto_adapter_create() is used for creating adapter
instance, eventdev is reconfigured with additional
``rte_event_dev_config::nb_event_ports`` parameter.
This eventdev reconfig logic is enhanced to increment 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``.
With this change the application is no longer need to configure the
eventdev with ``rte_event_dev_config::nb_single_link_event_port_queues``
parameter required for crypto adapter when the adapter is created
using above mentioned api.

+Event device configuration for service based adapter
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When rte_event_crypto_adapter_create() is used for creating
+adapter instance, eventdev is reconfigured with additional
+``rte_event_dev_config::nb_event_ports`` parameter.
+This eventdev reconfig logic also increment 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``.
+
+So the application is no longer need to configure the
+event device with ``rte_event_dev_config::nb_event_ports`` and
+``rte_event_dev_config::nb_single_link_event_port_queues``
+parameters required for crypto adapter when the adapter is created
