39 | This kernel module can be loaded in host kernel to accelerate |
| 40 | guest networking with virtio_net. Not to be confused with virtio_net | |
| 41 | module itself which needs to be loaded in guest kernel. | |

| 43 | To compile this driver as a module, choose M here: the module will | |

86 | This option allows vhost to support guests with a different byte |
| 87 | ordering from host while using legacy virtio. | |
| 88 | ||
| 89 | Userspace programs can control the feature using the | |
| 90 | VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls. | |
| 91 | ||
| 92 | This is only useful on a few platforms (ppc64 and arm64). Since it | |
| 93 | adds some overhead, it is disabled by default. | |

| 95 | If unsure, say "N". | |
