Neither of these work with Emil's scenario of a system that allows a
faster-than-standard speed.
How about: "Definition: Specifies the external MDIO bus clock speed to
be used, if different from the standard 2.5 MHz. This may be due to the
standard speed being unsupported (e.g. due to a hardware problem), or to
advertise that all relevant components in the system support a faster
speed."

If you don't have a realistic example to use, don't put it in the
example at all. 2.5MHz is the worst example to use because that's the
default and there'd be no reason to use the property at all.
