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?
Keyboard shortcuts
hback out one level
jnext message in thread
kprevious message in thread
ldrill in
