   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.

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

  35         vhost_vsock.

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

  50           Userspace programs can control the feature using the
  51           VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
  52
  53           This is only useful on a few platforms (ppc64 and arm64). Since it
  54           adds some overhead, it is disabled by default.

  56           If unsure, say "N".
