+/**
+ * @file
+ * RTE Pipeline Input Port Actions
+ *
+ * This API provides a common set of actions for pipeline input ports to speed
+ * up application development.
+ *
+ * Each pipeline input port can be assigned an action handler to be executed
+ * on every input packet during the pipeline execution. The pipeline library
+ * allows the user to define his own input port actions by providing customized
+ * input port action handler. While the user can still follow this process, this
+ * API is intended to provide a quicker development alternative for a set of
+ * predefined actions.
+ *
+ * The typical steps to use this API are:
+ * - Define an input port action profile. This is a configuration template that
+ * can potentially be shared by multiple input ports from the same or
+ * different pipelines, with different input ports from the same pipeline
+ * able to use different action profiles. For every input port using a given
+ * action profile, the profile defines the set of actions and the action
+ * configuration to be executed by the input port. API functions:
+ * rte_port_in_action_profile_create(),
+ * rte_port_in_action_profile_action_register(),
+ * rte_port_in_action_profile_freeze().
+ *
+ * - Instantiate the input port action profile to create input port action
+ * objects. Each pipeline input port has its own action object.
+ * API functions: rte_port_in_action_create().
+ *
+ * - Use the input port action object to generate the input port action handler
+ * invoked by the pipeline. API functions:
+ * rte_port_in_action_params_get().
+ *
+ * - Use the input port action object to generate the internal data structures
+ * used by the input port action handler based on given action parameters.
+ * API functions: rte_port_in_action_apply().
+ *
+ * @warning
+ * @b EXPERIMENTAL: this API may change without prior notice
