| This option allows vhost to support guests with a different byte | |

| 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". | |
