ARP monitoring does not work when we have a network in the
following configuration:
eth0----+ +----bond0.100----br0-100---{+virtual machines
| |
+----bond0----+----br0---(fixed IP)->--{LAN arp_ip_target}
| |
eth1----+ +----bond0.200----br0-200---{+virtual machines
This patch extends bond_arp_send_all to also check if a device
is also in a bridge.
This is related to the following issues:
