| 7 | This kernel module can be loaded in host kernel to accelerate | |
| 8 | guest networking with virtio_net. Not to be confused with virtio_net | |
| 9 | module itself which needs to be loaded in guest kernel. | |
| 10 | ||
| 11 | To compile this driver as a module, choose M here: the module will | |
| 12 | be called vhost_net. | |

| 39 | ---help--- | |
| 40 | This option allows vhost to support guests with a different byte | |
| 41 | ordering from host while using legacy virtio. | |
| 42 | ||
| 43 | Userspace programs can control the feature using the | |
| 44 | VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls. | |
| 45 | ||
| 46 | This is only useful on a few platforms (ppc64 and arm64). Since it | |
| 47 | adds some overhead, it is disabled by default. | |
| 48 | ||
| 49 | If unsure, say "N". |
