The librte_vhost API is used in two ways: 1. As a vhost net device backend via rte_vhost_enqueue/dequeue_burst(). 2. As a library for implementing vhost device backends. There is no distinction between the two at the API level or in the librte_vhost implementation. For example, device state is kept in "struct virtio_net" regardless of whether this is actually a net device backend or whether the built-in virtio_net.c driver is in use. The virtio_net.c driver should be a librte_vhost API client just like the vhost-scsi code and have no special access to vhost.h internals. Unfortunately, fixing this requires significant librte_vhost API changes. This patch takes a different approach: keep the librte_vhost API unchanged but track whether the built-in virtio_net.c driver is in use. See the next patch for a bug fix that requires knowledge of whether virtio_net.c is in use.
