Define the InOrderVQElement structure for the VIRTIO_F_IN_ORDER
transport feature implementation.
The InOrderVQElement structure is used to encapsulate out-of-order
VirtQueueElement data that was processed by the host. This data
includes:
- The processed VirtQueueElement (elem)
- Length of data (len)
- VirtQueueElement array index (idx)
- Number of processed VirtQueueElements (count)
InOrderVQElements will be stored in a buffering mechanism until an
order can be achieved.
