Am I reading properly that if you put "no-hw-checksum" in the device- tree you *enable* HW checksum ? This doesn't look right to me... The logic should be: if (pdev->dev.of_node && of_property_read_bool(pdev->dev.of_node, "no-hw-checksum")) netdev->features &= ~NETIF_F_IP_CSUM; -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
