This patch enables the virtio-net tx queue size to be configurable between 256 (the default queue size) and 1024 by the user when the vhost-user backend is used. Currently, the maximum tx queue size for other backends is 512 due to the following limitations: - QEMU backend: the QEMU backend implementation in some cases may send 1024+1 iovs to writev. - Vhost_net backend: there are possibilities that the guest sends a vring_desc of memory which crosses a MemoryRegion thereby generating more than 1024 iovs after translation from guest-physical address in the backend.
