We're having a problem getting the SMSC LAN91C111 to work on one of
our ColdFire boards. We can access memory-mapped MAC registers, but we
can't get the serial Management Interface to the PHY to work.
Selecting the external PHY connection to break our MI signals out,
everything looks fine on the scope, right number of clock pulses etc.,

Am I missing something obvious?
