Now, virtio-net already supports per-queue notification coalescing parameter
setting. Based on this, we use the netdim library[1] of linux to support
dynamic notification coalescing moderation for virtio-net.

Do you have perf numbers?

We have only tested the control path now. The acquisition of perf 
numbers depends on the
modification of our backend, and it will take a few days. I will bring 
it in the next version!

Thanks!

Thanks
