Current radix-based implementation of lookup tables in ipfw does
not support non-contiguous prefixes while this type of lookup is
needed to write CPU-effective firewall configurations.
For some of the cases we can reach the goal using a masked table
lookup by adding masked (e.g. zero non-significant bits) records
into a table and then zero non-significant bits in lookup key
prior to making a table lookup.
