The first patch fixes a protocol compliance issue where VHOST_USER_GET_QUEUE_NUM was incorrectly returning the number of virtqueues instead of queue pairs. The vhost-user specification clearly states this should return the maximum number of queues supported by the backend. Since each queue consists of an RX/TX pair, the correct value is VHOST_USER_MAX_VQS / 2. This patch also renames the constant to better reflect its meaning.
The second and third patches address virtqueue handling in the UDP and TCP receive paths. These changes pass the virtqueue pointer explicitly to the receive functions, enabling proper queue selection for future multiqueue support. This ensures packets are processed on the same virtqueue as the caller.
These changes lay the groundwork for full multiqueue support while fixing existing protocol compliance issues.
