[RFC 1/2] virtio-ring: Use threshold for switching to indirect descriptors
Currently if VIRTIO_RING_F_INDIRECT_DESC is enabled we will use indirect
descriptors even if we have plenty of space in the ring. This means that
we take a performance hit at all times due to the overhead of creating
indirect descriptors.
Instead, use it only after we're below a configurable offset.
