[dpdk-dev] [PATCH v6 2/9] net/virtio: enable vectorized path

[Marvin Liu]

Previously, virtio split ring vectorized path is enabled as default.
This is not suitable for everyone because of that path not follow virtio
spec. Add new config for virtio vectorized path selection. By default
vectorized path is enabled.
