This API provides a common set of actions for pipeline tables to speed up application development. Each match-action rule added to a pipeline table has associated data that stores the action context. This data is input to the table action handler called for every input packet that hits the rule as part of the table lookup during the pipeline execution. The pipeline library allows the user to define his own table actions by providing customized table action handlers (table lookup) and complete freedom of setting the rules and their data (table rule add/delete). 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 a table action profile. This is a configuration template that can potentially be shared by multiple tables from the same or different pipelines, with different tables from the same pipeline likely to use different action profiles. For every table using a given action profile, the profile defines the set of actions and the action configuration to be implemented for all the table rules. API functions: rte_table_action_profile_create(), rte_table_action_profile_action_register(), rte_table_action_profile_freeze(). • Instantiate the table action profile to create table action objects. Each pipeline table has its own table action object. API functions: rte_table_action_create(). • Use the table action object to generate the pipeline table action handlers (invoked by the pipeline table lookup operation). API functions: rte_table_action_table_params_get(). • Use the table action object to generate the rule data (for the pipeline table rule add operation) based on given action parameters. API functions: rte_table_action_apply(). • Use the table action object to read action data (e.g. stats counters) for any given rule. API functions: rte_table_action_XYZ_read().

Parameters profile Table profile action handle (needs to be valid and not in frozen state). type Specific table action to be registered for profile. action_config Configuration for the type action.

Parameters action Handle to table action object (needs to be valid). data Data byte array (typically table rule data) with meter action previously applied on it. tc_mask Bit mask defining which traffic classes should have the meter stats counters read from data and stored into stats. If bit N is set in this bit mask, then traffic class N is part of this operation, otherwise it is not. If bit N is set in this bit mask, then traffic class N must be one of the traffic classes that are enabled for the meter action in the table action profile used by the action object. stats When non-NULL, it points to the area where the meter stats counters read from data are saved. Only the meter stats counters for the tc_mask traffic classes are read and stored to stats. clear When non-zero, the meter stats counters are cleared (i.e. set to zero), otherwise the counters are not modified.
