>From the commit:

"If we don't compile with CONFIG_IPV6_ROUTER_PREF (RFC4191 support) a
neighbour is only valid if its nud_state is NUD_VALID. I did not find
any references that we should probe the router on route insertion time
via the other RFCs. So skip this route in that case."

So I assume that the bug would still be there.
