Nice.
I will test these as soon as they make it into net-next (just easier
for me given the setup).
I should confirm that:
The previous patches which are already in net-next from yesterday do
improve performance to under 1 minute. Can we call that a several-factor
improvement?;->
Are you planning to give some tender loving to the virtual devices
as well (gre etc) or is that taken care of now you have a pernet batch
exit op?
cheers,
