[Qemu-devel] [virtio] virtqueue_add_sgs

[Catalin Vasile]

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?
