David Ahern eb7bef1db6 net: ipv6: Compare lwstate in detecting duplicate nexthops ... commit f06b7549b79e29a672336d4e134524373fb7a232 upstream. Lennert reported a failure to add different mpls encaps in a multipath route: $ ip -6 route add 1234::/16 \ nexthop encap mpls 10 via fe80::1 dev ens3 \ nexthop encap mpls 20 via fe80::1 dev ens3 RTNETLINK answers: File exists The problem is that the duplicate nexthop detection does not compare lwtunnel configuration. Add it.
