[dpdk-dev] Increasing number of txd and rxd from 256 to 1024 for virtio-net-pmd-1.1

Can you share your virtio driver with me ? Do you mean to create multiple queues, each has 256 txd/rxd ? The packets could be stored into the freeslots in those queues. But how can the virtio pmd codes feed the slots down to the hardware to deliver them ? The other question is that I was using vh
