Should be VNET_MAXPACKET. Also, some general questions- how does this work for broadcast packets, e.g., if I do "ping -b <broadcast address> -s 60000" the 65535 MTU is only useful betwen two guests if inter-vnet-link is set to on, right? (i.e., can you use it when you go from a guest to another IP address on a different physical host)? --Sowmini -- 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
