Even if the device has "huge queues" I still think we need a software queue for when the hardware one backs up. It is even beneficial to stick with reasonably sized TX queues because it keeps the total resident state accessed by the CPU within the bounds of the L2 cache. If you go past that it actually hurts to make the TX queue larger instead of helps even if it means you never hit back pressure. - 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
