- This option allows vhost to support guests with a different byte
- ordering from host while using legacy virtio.
- Userspace programs can control the feature using the
- VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
- This is only useful on a few platforms (ppc64 and arm64). Since it
- adds some overhead, it is disabled by default.
- If unsure, say "N".
