Unicast probes are possible.
If it is broadcast/multicast then pkt_type will be PACKET_{BROAD,MULTI}CAST.
The existing ipv4 proxy-arp code is saying (as I read it) to not delay the
response if this is a unicast probe. This is one of the behaviors that
Julian is modifying slightly.
For everyone's edification, when looking at changes Julian is suggesting, realize
that his interests lie in IPVS like applications, so consider the corner case
situations that such setups might be interested in and you'll see clearly the
impetus for all of his ARP change proposals :-)
