      What's the feature?

       

      In order to improve TCP performance with OVS-DPDK, we could implement VIRTIO_NET_F_VQ_NOTF_COAL Virtio feature in DPDK Vhost library.

       

      Preliminary tests have shown that it improves the batching, with more efficient NAPI polls.It should also reduce vCPU load has less interrupts are injected into the guest.

      Why is it needed?

       

      Who will benefit?
