vio_init_queue()

Initialize a single virtqueue in the device

Synopsis:

#include <qvm/vio.h>

int vio_init_queue(struct vio_state *vsp,
                   unsigned qidx,
                   unsigned max_size)

vsp: A pointer to the vdev's state structure.
qidx: The index number of the queue to be initialized.
max_size: The maximum number of descriptors the device allows in the queue.

Use this function during startup, but only after your VDEV_CTRL_OPTIONS_END callback.

EOK if successful; otherwise errno.
