- Anything selecting VHOST or VHOST_RING must depend on VHOST_DPN.
- This excludes the deprecated ARM ABI since that forces a 4 byte
- alignment on all structs - incompatible with virtio spec requirements.

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

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

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