| 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". |
