I am aware that the S in RSS was for scaling, I obviously had a error between my brain and my keyboard. Anyway, I look forward to the changes appearing in ethtool, and if I see a opportunity to help out, then I will offer my assistance. Perhaps I'll try and add the ethtool rx_hash support to the ixgbe drivers (since I have a couple of these cards). I guess I'll speak to the Intel guys about that. thanks for your time Andrew -- 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
