still regarding ip6_tunnel and xfrm6_tunnel

[Hugo Santos]

Hi,

   When ip6_tunnel discards a packet because there is no tunnel
 associated with it, it sends a ICMPV6_DEST_UNREACH error to the packet
 source. However, when using ip6_tunnel and xfrm6_tunnel, if there is a
 a tunnel spi allocated for it, it may be processed dispite ip6_tunnel
 having already sent the error to the source. Is this behaviour
 expected?

   Thanks,

      Hugo
