AF_VSOCK test suite-------------------These tests exercise net/vmw_vsock/ host<->guest sockets for VMware, KVM, andHyper-V. The following tests are available:   * vsock_test - core AF_VSOCK socket functionality  * vsock_diag_test - vsock_diag.ko module for listing open sockets The following prerequisite steps are not automated and must be performed priorto running tests: 1. Build the kernel, make headers_install, and build these tests.2. Install the kernel and tests on the host.3. Install the kernel and tests inside the guest.4. Boot the guest and ensure that the AF_VSOCK transport is enabled. Invoke test binaries in both directions as follows:   # host=server, guest=client  (host)# $TEST_BINARY --mode=server \                       --control-port=1234 \                       --peer-cid=3  (guest)# $TEST_BINARY --mode=client \                        --control-host=$HOST_IP \                        --control-port=1234 \                        --peer-cid=2   # host=client, guest=server  (guest)# $TEST_BINARY --mode=server \                        --control-port=1234 \                        --peer-cid=2  (host)# $TEST_BINARY --mode=client \                       --control-port=$GUEST_IP \                       --control-port=1234 \                       --peer-cid=3
