But with a new option is better for us. Maybe some people use latest iproute source with under kernel 3.3.0, some don't. -m option will take different user experience, specially for UDP socket. Currently -m option has no effect on UDP socket which i will submit another patch to export memory information for. new option, fresh experience. (Exporting out memory information will help us to analysis dropped packets which recorded in RcvbufErrors and SndbufErrors.) -- 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
