ethtool is the best way IMHO. As you already noted you will have to git pull the latest version - just now they posted a 2.6.33-pre1 build of ethtool - that should work as well. Then you can modify your startup scripts to disable GRO before bringing the interface up. Or ... the driver is open source after all, so you can modify the code to disable it by default. Find the following line in igb_main.c: netdev->features |= NETIF_F_GRO; and change it to: netdev->features &= ~NETIF_F_GRO; Thanks, Emil ________________________________

I know I can do an ethtool -K ethx gro off, but is there a better way to disable it? Ideally something that keeps it from coming on before I can turn it off.

If you have issues just disable it.
