If I send to the backend out buffers using multiple sgs, what should I expect when the user sends me back the result? What should I expect to get when I do a virtqueue_get_buf()? Do I need to make multiple calls to virtqueue_get_buf() in order to get all my out buffers? Or it returns with the first buffer and then I somehow have to guess the other buffers from the data received in the first buffer?
