Hi, I understand that IFG configured in Ethernet medium is 9.6micro seconds. I am trying to flood the wire with too many UDP packets and facing lotsa packet loss. Is there any way of configuring this IFG value (say to i milli second) programatically in "C" Any help would be appreciated Re, Avni - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
