+Set/Get adapter runtime configuration parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The runtime configuration parameters of adapter can be set/read using
+``rte_event_eth_tx_adapter_runtime_params_set()`` and
+``rte_event_eth_tx_adapter_runtime_params_get()`` respectively. The parameters

+
+The adapter flush threshold also can be configured using

+
+``rte_event_eth_tx_adapter_runtime_params_get()`` function retrieves the adapter
+params that are defined in ``struct rte_event_eth_tx_adapter_runtime_params``.
