Also, when I put mge1's ethernet link address (MAC) into .dts file, it is
initialised with this value, as expected. But nothing else changed - receiving
frames works, sending does not.
Maybe it's time for some mge's source tweaking, but I have absolutelly no idea
where to begin.
I suspect the PHY asignment. The current code tries to retrieve the PHY
number from the dts but then probes for PHYs and uses the first one.
Can you try the following patch? I unfortunately don't have hardware
with two PHYs.
Make sure you have the correct phy number set for mge1 (probably just
0x1) in your dts.
It's probably not a final solution though as it relies on the dts for
information which can be probed automatically.
