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 EXPERIMENTAL: this API may change without prior notice Definition in file rte_port_in_action.h.

Function Documentation __rte_experimental struct rte_port_in_action_profile * rte_port_in_action_profile_create (uint32_t socket_id) Input port action profile create. Parameters socket_id CPU socket ID for the internal data structures memory allocation. Returns Input port action profile handle on success, NULL otherwise. __rte_experimental int rte_port_in_action_profile_free (struct rte_port_in_action_profile * profile) Input port action profile free. Parameters profile Input port action profile handle (needs to be valid). If profile is NULL, no operation is performed. Returns Always zero. __rte_experimental int rte_port_in_action_profile_action_register (struct rte_port_in_action_profile * profile, enum rte_port_in_action_type type, void * action_config) Input port action profile action register. Parameters profile Input port action profile handle (needs to be valid and not in frozen state). type Specific input port action to be registered for profile. action_config Configuration for the type action. If struct rte_port_in_action_*type*_config is defined, it needs to point to a valid instance of this structure, otherwise it needs to be set to NULL. Returns Zero on success, non-zero error code otherwise. __rte_experimental int rte_port_in_action_profile_freeze (struct rte_port_in_action_profile * profile) Input port action profile freeze. Once this function is called successfully, the given profile enters the frozen state with the following immediate effects: no more actions can be registered for this profile, so the profile can be instantiated to create input port action objects. Parameters profile Input port profile action handle (needs to be valid and not in frozen state). Returns Zero on success, non-zero error code otherwise. See also rte_port_in_action_create() __rte_experimental struct rte_port_in_action * rte_port_in_action_create (struct rte_port_in_action_profile * profile, uint32_t socket_id) Input port action create. Instantiates the given input port action profile to create an input port action object. Parameters profile Input port profile action handle (needs to be valid and in frozen state). socket_id CPU socket ID where the internal data structures required by the new input port action object should be allocated. Returns Handle to input port action object on success, NULL on error. __rte_experimental int rte_port_in_action_free (struct rte_port_in_action * action) Input port action free. Parameters action Handle to input port action object (needs to be valid). If action is NULL, no operation is performed. Returns Always zero. __rte_experimental int rte_port_in_action_params_get (struct rte_port_in_action * action, struct rte_pipeline_port_in_params * params) Input port params get. Parameters action Handle to input port action object (needs to be valid). params Pipeline input port parameters (needs to be pre-allocated). Returns Zero on success, non-zero error code otherwise. __rte_experimental int rte_port_in_action_apply (struct rte_port_in_action * action, enum rte_port_in_action_type type, void * action_params) Input port action apply. Parameters action Handle to input port action object (needs to be valid). type Specific input port action previously registered for the input port action profile of the action object. action_params Parameters for the type action. If struct rte_port_in_action_*type*_params is defined, it needs to point to a valid instance of this structure, otherwise it needs to be set to NULL. Returns Zero on success, non-zero error code otherwise. Author Generated automatically by Doxygen for DPDK from the source code. Version 25.11.0 Thu Jun 11 2026 rte_port_in_action.h(3)
