While this might be true,

struct ifnet {                          /* and the entries */
[...]
        u_short if_index;               /* numeric abbreviation for this if */

in practice today 16-bit serial numbers are repeated.

Not that this says anything about names and addresses being
repeated less frequently than if_index, just that 32 or 64 bit
if_index would be nice. :)
