David, I had to revert 1f3c8804acba841b5573b953f5560d2683d2db0d
(bonding: allow arp_ip_targets on separate vlans to use arp validation)

Or else, my vlan devices dont work (unfortunatly I dont have much time
these days to debug the thing)

My config :

              +---------+
vlan.103 -----+ bond0   +--- eth1 (bnx2)
              |         +
vlan.825 -----+         +--- eth2 (tg3)
              +---------+

$ cat /proc/net/bonding/bond0

bonding: allow arp_ip_targets on separate vlans to use arp validation

This allows a bond device to specify an arp_ip_target as a host that is
not on the same vlan as the base bond device and still use arp
validation.  A configuration like this, now works:

BONDING_OPTS="mode=active-backup arp_interval=1000 arp_ip_target=10.0.100.1 arp_validate=3"
