I agree, the URL suggests:
> CONFIG_REGULATOR_DEBUG=y
> CONFIG_REGULATOR_VIRTUAL_CONSUMER=y
> CONFIG_REGULATOR_USERSPACE_CONSUMER=y
> CONFIG_PWM_SUN4I=y
Of which the first is a debug option, the second two are "virtual" (in
that they don't relate to any real hardware) and the final one, while
related to h/w it is not h/w which should have anything to do with
Ethernet.
My best guess is that one of these has some sort of knock-on dependency
which causes something else to be enabled. I'm going to investigate
that possibility now... In the meantime:

Yes, please.
It would also be useful/interesting to know which Allwinner A10 device
this was with.
