[Click] questions about arpquerier

[Eddie Kohler]

Hi,

ARPQuerier expects its input packets to be IP.  your configuration sends ARP 
queries to ARPQuerier, which does not make sense.  Look at fake-iprouter.click 
for examples; Classifier(12/0800) detects IP packets; you then need to verify 
them as IP using CHeckIPHeader.
