11 * RTE generic flow API (driver side)
13 * This file provides implementation helpers for internal use by PMDs, they
14 * are not intended to be exposed to applications and are not subject to ABI
20 #include "rte_ethdev.h"
21 #include "ethdev_driver.h"
29 * Generic flow operations structure implemented and returned by PMDs.
31 * These callback functions are not supposed to be used by applications
32 * directly, which must rely on the API defined in rte_flow.h.
34 * Public-facing wrapper functions perform a few consistency checks so that
35 * unimplemented (i.e. NULL) callbacks simply return -ENOTSUP. These
36 * callbacks otherwise only differ by their first argument (with port ID
37 * already resolved to a pointer to struct rte_eth_dev).
