Hi Antonio

General question. In the Linux ARP decode code is:

/*
 *      Check for bad requests for 127.x.x.x and requests for multicast
 *      addresses.  If this is one such, delete it.
 */
        if (ipv4_is_loopback(tip) || ipv4_is_multicast(tip))
                goto out;

I don't see the same filtering here. What would happen if you did
receiver and cached such a bad request?

In a similar direction, how does duplicate address detection work?
i.e. i ARP my own address to see if somebody else is using it? 

Or do i just need to RTFM your GSOC documentation :-)

   Andrew
