32 This kernel module can be loaded in host kernel to accelerate
33 guest networking with virtio_net. Not to be confused with virtio_net
34 module itself which needs to be loaded in guest kernel.

36 To compile this driver as a module, choose M here: the module will
37 be called vhost_net.

55 This kernel module can be loaded in the host kernel to provide AF_VSOCK
56 sockets for communicating with guests. The guests must have the
57 virtio_transport.ko driver loaded to use the virtio-vsock device.

78 This option allows vhost to support guests with a different byte
79 ordering from host while using legacy virtio.

81 Userspace programs can control the feature using the
82 VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
83
84 This is only useful on a few platforms (ppc64 and arm64). Since it
85 adds some overhead, it is disabled by default.

87 If unsure, say "N".
