Hm, not really. I've tested this with my Armada 370 Mirabox and Armada
XP Openblocks AX3-4 boards (I use kwboot to load the barebox image, so I
don't jump from U-Boot).

I guess we must be missing some config. What's confusing is that the
Mirabox and the RN104 should be pretty similar in this regard (e.g. they
use the same phy mode).

Sebastian, do you have any ideas?
