It can, but you have to make sure that you only examine IP-in-Ethernet
packets (whose IP header annotations are set). The easiest way to do this
is to give ARPQuerier 2 outputs. Then the first output will emit
IP-in-Ethernet packets, and the second will emit ARP queries. Ex:
... -> arpq::ARPQuerier(...);
q :: Queue;
arpq[0] /* IP packets */ -> IPClassifier(whatever) -> q;
arpq[1] /* ARP queries */ -> q;
