I am new to OVS-DPDK and trying to figure out the mechanism of vhost-user
multiqueue scenario. I understand that the PMD thread is created for
polling the queues of vhost-user or physical NIC and the affinity bind PMD
to queues. However, the PMD transmission side confused me, I would like to
learn PMD thread mechanism and how it distributes traffic to different
Let's consider this scenario: one PMD thread is responsible for two queues
of one vhost-user, when packet destined to the vhost-user, how it decide
which queue to trasmit? is there equivalence to RSS?
Traffic ==>PMD thread ==> ==>Virtio Frontend in VM
Thanks in advance
