Userspace implementations of network routing protocols sometimes need to tell RA-originated IPv6 routes from other kernel routes to make proper routing decisions. This makes most sense for RA routes with nexthops, namely, default routes and Route Information routes. The intended mean of preserving RA route origin in a netlink message is through indicating RTPROT_RA as protocol code. Function rt6_fill_node() tried to do that for default routes, but its test condition was taken wrong. This change is modeled after the original mailing list posting by Jeff Haran. It fixes the test condition for default route case and sets the same behaviour for Route Information case (both types use nexthops). Handling of the 3rd RA route type, Prefix Information, is left unchanged, as it stands for interface connected routes (without nexthops).
