The port needs to return the size of the variant part for states
where it didn't matter before.  Some ports, particularly among
those I listed, return the same unmodified fr_var, or at least
do not return a value based on fr_subtype as necessary.

As you know, a correct return-value on subsequent rounds is
necessary for correct fr_address calculation.
