Netlink: Ignore dead routes
With net.ipv4.conf.XXX.ignore_routes_with_linkdown sysctl, a user can ensure the kernel does not use a route whose target interface is down. Such route is marked with a 'dead' / RTNH_F_DEAD flag. Ignore these routes or multipath nexthops during scan. Thanks to Vincent Bernat for the original patch.
