Patch [1] added support for RSS flow expansion.
It was added in ethdev for public use, but until now it is used only
by MLX5 PMD.
To allow local changes in this code, this patch removes it from ethdev
and moves it to MLX5 PMD file.

* 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:
|
|
*
|
|
* \code
|
|
*
|
|
* // 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;
|
|
* }
|
|
*
|
|
* \endcode
|
|
*
|
|
* 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).
