When this box is receiving it's moving about 3x ass much data and has a _lower_ (absolute, not per packet) interrupt load. -- --- Larry McVoy lm at bitmover.com http://www.bitkeeper.com - 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
