I don't think this is really true.  In some ways Linux behaves as if
IP addresses are per-host (eg ARP responses can go out any interface)
but really IP addresses are attached to an interface.  Every struct
net_device has a struct in_device, and every struct in_device has a
list of struct in_ifaddrs for the device's IP addresses.
