In the end I want to reduce the CPU utilization. And one way to do that is LRO which also works only well if there are more then just a very few packets to aggregate. So at least our driver (eHEA) would benefit from a mix of timer based polling and plain NAPI (depending on load situations). If there is no need for a generic mechanism for this kind of network adapters, then we can just leave this to each device driver.
No objections from me either way, if something works then fine. Let's come back to this once you have a tested sample implementation that does what you want, ok?
