I have 2 Pegasos running 3.0, but in my case mv643xx_eth is non-modular
and /sys/class/mdio_bus/0 exists and points to
../../devices/platform/mv643xx_eth.0/mdio_bus/0
which is correct as far as I can say.
Is it a regression from 3.0 or not? Try to make it non modular and see
what happens. If it is a regression, could you try to bisect it?
I won't be close enough to the machines to do a regression
hunt myself before a week or 3 (really, maybe next week,
I don't yet know, but for sure starting on Nov 8th).
