We cannot build larger that just under 64K frame due to IP header length field limitations. We have to encode the total length in the ipv4 header, so there is no way to get around the 16-bit length limitation. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
