    * If the device continues existing even if it doesn't work, the kernel needs a way to decide whether this is a route might be chosen, specially if several are available. This is called the ``dead gateway detection''; it works for any kind of unicast routes (multipath/unipath, input/output) and provided by these patches.

It is because of the patches that the kernel knows how to distinguish the route not only by source and destination, but also by device and gateway. Also, at least when  each line has a different device, the kernel's reverse path checking ''(rp_filter)'' will work correctly.

    * The NAT system has no idea how to deal with alternative routes, this is something the routing system has to do. And one of the additions of these patches is make the routing system prepare the route of an individual packet for the nat system, such that it looks as if it where the only possible route.
