Note that the receiver reacts to incoming packet, sending a DUPACK, so its not a backlogdrop. tcpdump trace is really incomplete, I asked tcpdump -vv but got nothing from chptx, assuming this is a real name. packet might be rejected because of a zero receiver window, who knows. I might search in my basement this crystal ball I might have. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
