Without looking at the carp code, I can tell you that its addressing 
hook is implemented as a pass-through in ether_input(). carps are not 
IFT_ETHER, therefore they shouldn't emit gratuitous ARP or otherwise 
when an address is configured on one.

So I'll leave this up to someone who knows the carp code, as this is 
most likely where the ARP originated from.
