It is already there in one form. See following in existing header file.
/**
* Meter policy
*/
struct rte_mtr_meter_policy_params {
/**
* Policy action list per color.
* actions[i] potentially represents a chain of rte_flow actions
* terminated by the END action, exactly as specified by the rte_flow
* API for the flow definition, and not just a single action.
*/
const struct rte_flow_action *actions[RTE_COLORS];
};
