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.
