I just tested on dxr2 (AM3352 based board) with latest mainline U-Boot. And the network performance is a bit better. But not as good as yours. Here my numbers: Without this patch: ~400 KiB/s With this patch: ~570 KiB/s Any ideas what might be missing on my platform? Why the speed is not as good? Thanks, Stefan
