Yes, classification is setup per pktio interface and is done right after packet arriving the device. A list of interfaces is device (implementation) specific. Valid interfaces may include e.g. eth0, 10ge_0, 10ge_loop0, etc. The only reserved interface name is "loop", which must be a packet loopback interface. There can be several other packet input or loopback interfaces. Classification can be configured for any interface.
