This series was spun off from: "[PATCH 0/3] virtio-net: Convert feature properties to OnOffAuto" (https://patchew.org/QEMU/[email protected]/)
Some features are not always available with vhost. Legacy features are not available with vp_vdpa in particular. virtio devices used to disable them when not available even if the corresponding properties were explicitly set to "on". QEMU already has OnOffAuto type, which includes the "auto" value to let it automatically decide the effective value. Convert feature properties to OnOffAuto and set them "auto" by default to utilize it. This allows QEMU to report an error if they are set "on" and the corresponding features are not available.
