I met a Bug when I add ip target with the wrong ip address:
echo +500.500.500.500 > /sys/class/net/bond0/bonding/arp_ip_target
the wrong ip address will transfor to 245.245.245.244 and add
to the ip target success, it is uncorrect, so I add checks to avoid
adding wrong address.
The in4_pton() will set wrong ip address to 0.0.0.0, it will return by
the next check and will not add to ip target.

Your mail client, apparently, transformed tabs into spaces, so the patch
doesn't apply.

yes, the patch was made in net-next, I forget to make it in net, I'll
send it by office mail in office later.
