  | Why don't we make cf_unit and dv_unit unsigned int?

Even if there was enough minor unit number space to support that,
all it is doing is altering the values at which weirdness appears.

I cannot imagine a use case for > 30000 pseudo devices of any
type (or any other kind of interface or device) - the closest I can
see if with vlans where it is nice to be able to have the vlan number
and the interface number matching - but that takes just 12 bits.
