Subject: Re : Re : Re : Re : Re : Bonding : Monitoring of 4965 wireless card

I try arp monitoring but it doesn't work! Test an ip, the interface must have an address, and the dhcpcd is launch by ifplugd if bond0 is linked ... so it goes around in circles.
So i return to miimon, and i figured out that bond detect when wlan0 is associated and set it active interface. But when i switch rf_kill it don't react. So i try to deassociate and magic it detect interface off!! I presume it is a bug of the wlan driver which not re-initialise the info on the wlan. So i made a small script in acpi to provide that behavior.

    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.
