 * FUNCTION:            iso_usrreq
 *
 * PURPOSE:                     Provide a means of getting from soo_ioctl to iso_control
 *
 * RETURNS:                     unix error code
 *
 * SIDE EFFECTS:
 *
 * NOTES:                       Only PRU_CONTROL causes anything to occur. PRU_ATTACH
 *                                      and PRU_DETACH are noops so socket and close don't return
 *                                      an error code.
