This series adds *XDP* support and as a result, the AF_XDP batteries are included. ;-) Björn
In addition the new dma allocation scheme offers a 10% boost on Rx pps rate using 64b packets - patch [1/2]: Use a different allocation scheme for Rx DMA buffers to prepare the driver for AF_XDP support - patch [2/2]: Add XDP support without zero-copy test and performance numbers (64b packets): ------------------------------------------- - Normal SKBs on Rx: ~217kpps test: pktgen -> intel i210 -> netsec -> XDP_TX/XDP_REDIRECT - XDP_TX: 320kpps - XDP_REDIRECT: 320kpps qemu -> pktgen -> virtio -> ndo_xdp_xmit -> netsec - ndo_xdp_xmit: Could not send more than 120kpps. Interface forwarded that with success Changes since v2: - Always allocate Rx buffers with XDP_PACKET_HEADROOMBjörn Töpel:- Added locking in the Tx queue Jesper Dangaard Brouer: - Added support for .ndo_xdp_xmit - XDP_TX does not flush every packet Changes since v1: - patch [2/2]: Toshiaki Makita: - Added XDP_PACKET_HEADROOM - Fixed a bug on XDP_PASS case - Using extact for error messaging instead of netdev_warn, when trying to setup XDP Ilias Apalodimas (2): net: socionext: different approach on DMA net: socionext: add XDP support drivers/net/ethernet/socionext/netsec.c | 541 +++++++++++++++++++++++++------- 1 file changed, 426 insertions(+), 115 deletions(-)
