It was suggested to move existing RSS to rte_flow. + This can be better for users, and may save effort for CPK development. + RSS enabling: now the rss enable is done through rte_eth_rss_conf.rss_hf, + need to enable it on rte_flow API . Need to implement it on igb ixgbe and + i40e. + RSS input set changing: now the input set changing is done through + rte_eth_dev_filter_ctrl, need to enable it on rte_flow API. + Need to implement it on i40e. + It will make the DDP and FXP on NICs can be changed by rte_flow API. + New packet type group or pctype can be done in driver instead of the + format of private API. + +Prerequisites +============= + +1.
