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
