[ Upstream commit be48220edd48ca0d569782992840488a52373a24 ] MPLS does not support nexthops with an MPLS address family. Specifically, it does not handle RTA_GATEWAY attribute. Make it clear by returning an error. Fixes: 03c0566542f4c ("mpls: Netlink commands to add, remove, and dump routes") Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.
