20 * This file will include functions that will drive the
21 * kernel module tusb to test various usb functions
22 * and kernel calls. Each function will need to setup the tif
23 * structure so that the in parameters and out parameters
24 * are correctly initialized
25 *
26 * use tif structure for passing params between user
27 * space and kernel space, in some tests it is really
28 * not needed but makes easy to maintain all tests if
29 * have the same process to read in params in the
30 * kernel module no matter what the test is
