Subject: [PATCH] Can not send icmp netunreach packet

Hi All

   There is a bug about icmp netunreach.
   If the kernel does not find a route for a packet, 
   it must send a icmp netunreach packet to the source host, 
   and  discard  the packet. But the  kernel  does not send 
   a icmp netunreach packet because of the  fib_lookup
   return value  of -ESRCH when a route  is not found.
