When the action of an xdp program was XDP_TX, lan966x was creating a xdp_frame and use this one to send the frame back. But it is also possible to send back the frame without needing a xdp_frame, because it is possible to send it back using the page. And then once the frame is transmitted is possible to use directly page_pool_recycle_direct as lan966x is using page pools. This would save some CPU usage on this path, which results in higher number of transmitted frames. Bellow are the statistics: Frame size: Improvement: 64 ~8% 256 ~11% 512 ~8% 1000 ~0% 1500 ~0% Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Reviewed-by: Alexander Lobakin <aleksander.lobakin@intel.com> Link: https://lore.kernel.org/r/20230422142344.3630602-1-horatiu.vultur@microchip.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
