Yes it's what i'm looking for. I don't understand how to change the arp_ip_target with the gateway, arp_ip_target is a module option.

    In other words, what I think you're saying (and I'm not entirely
sure here) is that you want probes to go to a remote node on the
network, and back, without having to actually know the identity of the
remote node (because, presumably, on a roaming type of wireless
configuration, your gateway and whatnot can change from time to time).

    Is that what you're looking for?

    That isn't available now, but might be straightforward to plug
into the address update system to keep the arp_ip_target up to date as
the current gateway as the gateway changes.  I haven't looked into the
details of doing that, but in theory it sounds straightforward.

	If you're running a relatively recent bonding driver (version
3.0.0 or later), the arp_ip_targets can be changed on the fly via sysfs,
e.g.,

echo +10.0.0.1 > /sys/class/net/bond0/bonding/arp_ip_target
echo -20.0.0.1 > /sys/class/net/bond0/bonding/arp_ip_target

	You can check out Documentation/networking/bonding.txt (in the
kernel source code) for more details.
