Basically that's just an optimization. The netmask/base address match has
to be done anyway, you can just save a few lookups. Interesting idea,

Nevetherless I doubt whether this would be faster than a no-special-cases-
no-caching optimized-data-structure thing like CEF (or whatever the
competition is doing to that effect).
