What is "basic"?
Usage: ... u32 [ match SELECTOR ... ] [ link HTID ] [ classid CLASSID ]

               [ ht HTID ] [ hashkey HASHKEY_SPEC ]

or         u32 divisor DIVISOR

Where: SELECTOR := SAMPLE SAMPLE ...
       SAMPLE := { ip | ip6 | udp | tcp | icmp | u{32|16|8} | mark }
                 SAMPLE_ARGS [ divisor DIVISOR ]
       FILTERID := X:Y:Z

NOTE: CLASSID is parsed at hexadecimal input.
