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.

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.

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".
