The choice is however done using an ifdef pre-processor macro. Because of that the scalar version was apparently not widely excersized/compiled. Due to some copy/paste errors, the scalar logic in lpm_process_event_pkt() retained a "continue" statement where it should utilize rfc1812_process() and return the port/BAD_PORT.
