| 34 | This option enables building a transitional driver, supporting | |
| 35 | both devices conforming to Virtio 1 specification, and legacy devices. | |
| 36 | If disabled, you get a slightly smaller, non-transitional driver, | |
| 37 | with no legacy compatibility. | |
| 38 | ||
| 39 | So look out into your driveway. Do you have a flying car? If | |
| 40 | so, you can happily disable this option and virtio will not | |
| 41 | break. Otherwise, leave it set. Unless you're testing what | |
| 42 | life will be like in The Future. | |
