Sure.
CLICK_NAME(name) is a macro to do scoping, especially in the ns  
version of Click. In all other cases, it generates ::name
So after macro processing, the line reads:
return ::hashcode(_src) + ::hashcode(_dst);
and those calls are on the hashcode method of EtherAddress, which can  
be found in include/click/etheraddress.hh
