As a general rule you must specifiy all lower-layer fields in order to match a higher-layer field - the switch does not make the assumption that just because you set tp_src/dst, it knows what protocol you wanted to match on (tcp, udp, others provided by extension, etc.), or that just because you provided those fields, that the ethertype must be IP. -- Nick
