I think I mentioned it somewhere before, but I'd like to do this
differently, like in [0].

That should work in a similar way and at least in my tests the reported
clock rate seems to be correct. As I said as well I haven't been able to
make the emac detect a link on my kylin boards, so it would be cool
if you could test if this different approach works in practice as well.


Thanks
Heiko
