Detailed Description

Generic flow operations structure implemented and returned by PMDs.

To implement this API, PMDs must handle the RTE_ETH_FILTER_GENERIC filter type in their .filter_ctrl callback function (struct eth_dev_ops) as well as the RTE_ETH_FILTER_GET filter operation.

If successful, this operation must result in a pointer to a PMD-specific struct rte_flow_ops written to the argument address as described below:

// PMD filter_ctrl callback

static const struct rte_flow_ops pmd_flow_ops = { ... };

switch (filter_type) {
case RTE_ETH_FILTER_GENERIC:
    if (filter_op != RTE_ETH_FILTER_GET)
        return -EINVAL;
    *(const void **)arg = &pmd_flow_ops;
    return 0;
}

See also rte_flow_ops_get().

These callback functions are not supposed to be used by applications directly, which must rely on the API defined in rte_flow.h.

Public-facing wrapper functions perform a few consistency checks so that unimplemented (i.e. NULL) callbacks simply return -ENOTSUP. These callbacks otherwise only differ by their first argument (with port ID already resolved to a pointer to struct rte_eth_dev).
