[Qemu-devel] vhost-net - virtio - multiqueue - rx queue selection

Hi folks,

I have a question regarding the algorithm used to select rx queue of
the VM in the case of multiqueue virtio-net on KVM.

Given a 4-tuple, how can we calculate the index of the receive queue
that virtio-net is going pick for that flow?  From some of the email
threads in some of the relevant forums, it seems RSS is not used.  But
documentations/threads do not talk about how a queue is picked.

Could you please help me with this?
