IPv6: `no matching routes` despite `any_ip` set to `true

I have an interface with `set_any_ip` set to `true`. However, it cannot be received when there is no route, as it can be clearly seen in the relevant code: ```rust if self .routes .lookup(&IpAddress::Ipv6(ipv6_repr.dst_addr), self.now) .is_none_or(|router_addr| !self.has_ip_addr(router_addr)) { net_trace!("Rejecting IPv6 packet; no matching routes"); return None; } ``` It looks like the `any_ip` boolean is not taken into account in this statement. Here is an example: ```rust let mut tun = TunTapInterface::new("tun0", Medium::Ip).unwrap(); let config = iface::Config::new(HardwareAddress::Ip); let mut iface = Interface::new(config, &mut tun, Instant::now()); iface.set_any_ip(true); // Now create your sockets and poll. ```
