If you want to use a single queue, just declare a single queue on your NIC... ethtool -L eth0 rx 1 tx 1 Multiqueue is not a requirement in your case. You can easily reach line rate with a single queue on a 10Gbe NIC. -- 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
