* When adding an IP address, kernel automatically adds a device route.
* This can be suppressed via the IFA_F_NOPREFIXROUTE address flag. For proper
* IPv6 support, we require kernel support for IFA_F_NOPREFIXROUTE and always
* add the device route manually.
*
* For IPv4, this flag is rather new and we don't rely on it yet. We want to use
* it (but currently still don't). So, for IPv4, kernel possibly adds a device
* route, however it has a wrong metric of zero. We add our own device route (with
* proper metric), but need to delete the route that kernel adds.
*
* The problem is, that kernel does not immediately add the route, when adding
* the address. It only shows up some time later. So, we register here a list
* of blacklisted routes, and when they show up within a time out, we assume it's
* the kernel generated one, and we delete it.
*
* Eventually, we want to get rid of this and use IFA_F_NOPREFIXROUTE for IPv4
* routes as well.
