Sounds like something which might be useful for other virtualized environments. At worst, they would be able to provide some similar facility, and therefore the configuration mechanism to turn this on should be unified. Perhaps an ethtool boolean flag setting or similar, rather than a baroque and driver specific sysfs knob. -- To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
