34 | This kernel module can be loaded in host kernel to accelerate |
| 35 | guest networking with virtio_net. Not to be confused with virtio_net | |
| 36 | module itself which needs to be loaded in guest kernel. | |
| 37 | ||
| 38 | To compile this driver as a module, choose M here: the module will | |
| 39 | be called vhost_net. | |

81 | This option allows vhost to support guests with a different byte |
| 82 | ordering from host while using legacy virtio. | |
| 83 | ||
| 84 | Userspace programs can control the feature using the | |
| 85 | VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls. | |
| 86 | ||
| 87 | This is only useful on a few platforms (ppc64 and arm64). Since it | |
| 88 | adds some overhead, it is disabled by default. | |

| 90 | If unsure, say "N". | |
