Hello Using next-20170323 produce a huge performance regression on my sunxi boards. On dwmac-sun8i, iperf goes from 94mbs/s to 37 when sending.
On cubieboard2(dwmac-sunxi), iperf made the kernel flood with "ndesc_get_rx_status: Oversized frame spanned multiple buffers" and network is lost after. Reverting aff3d9eff84399e433c4aca65a9bb236581bc082 fix the issue. I still try to found which part of this patch mades the performance lower. Regards Corentin Labbe
