I don't know this driver, but I smell that the comment might actually
be wrong or at least misleading - most likely no PHY reset is needed
here but a MAC address needs to be programmed into the controller -
which brings us back to the start of this discussion. [And note that
you still might need this when you want to use the ethernet interface
in Linux].

Best regards,

Wolfgang Denk

 The software required `Windows 95 or better', so I installed Linux.
