ipv6: assign rt6_info to inet6_ifaddr in init_loopback
Commit 25fb6ca4ed9cad72f14f61629b68dc03c0d9713f "net IPv6 : Fix broken IPv6 routing table after loopback down-up" forgot to assign rt6_info to the inet6_ifaddr. When disable the net device, the rt6_info which allocated in init_loopback will not be destroied in __ipv6_ifa_notify. This will trigger the waring message below [23527.916091] unregister_netdevice: waiting for tap0 to become free.
