This patch optimized the fdir update rate for i40e PF, by tracking whether the fdir rule being inserted into the guaranteed space or shared space. For the flows that are inserted to the guaranteed space, we assume that the insertion will always succeed as the hardware only report the "no enough space left" error. In this case, the software can directly return success and no need to retrieve the result from the hardware. When destroying a flow, we also assume the operation will succeed as the software has checked the flow is indeed in the hardware. See the fdir programming status descriptor format in the datasheet for more details. Signed-off-by: Chenmin Sun <chenmin.sun@intel.com> Reviewed-by: Jingjing Wu <jingjing.wu@intel.com>
