The l2tp [get|set]sockopt() code has fallen back to the UDP functions for socket option levels != SOL_PPPOL2TP since day one, but that has never actually worked, since the l2tp socket isn't an inet socket. As David Miller points out: "If we wanted this to work, it'd have to look up the tunnel and then use tunnel->sk, but I wonder how useful that would be" Since this can never have worked so nobody could possibly have depended on that functionality, just remove the broken code and return -EINVAL.
