* @brief Check the behaviour of rtems_bdbuf_read() function
* with different reports from disk device driver.
*
* Test sequence:
* -# Call rtems_bdbuf_read() function and return 0 from disk device
* driver ioctl() function, and the result of asynchronous read
* complete notification is successful.
* -# Check that rtems_bdbuf_read() returns RTEMS_SUCCESSFUL and
* provides buffer descriptor.
* -# Call rtems_bdbuf_read() function and return -1 from disk device
* driver ioctl() function (there will be no asynchronous read
* complete notification).
* -# Check that rtems_bdbuf_read() returns RTEMS_IO_ERROR.
* -# Call rtems_bdbuf_read() function and return 0 from disk device
* driver ioctl() function, but the result of asynchronous read
* complete notification is faulty (with some erroneous status).
* -# Check that rtems_bdbuf_read() returns that status and does not
* return buffer descriptor.
