    Netlink: Ignore dead routes · df83f626
    Ondřej Zajíček authored
    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.
