What do you want it for and where do you want it? I think there were
plans to export if_dname and if_dunit via sysctls, but I don't think
that ever happened and they aren't really ment to be user visiable.
There's also no requirement that ("%s%d", if_dname, if_dunit) ever have
been the name of the interface (for instance in enhanced cloners such as
stf(4) and vlan(4)).
