  97.   *            (i.e. HAL_PPP_MspInit() will not be executed).

  99.   *            HAL_PPP_DeInit() then HAL_PPP_Init(), user can make a call to this macro then HAL_PPP_Init().
  100.   *            In this later function, when the Handle's "State" field is set to 0, it will execute the function
  101.   *            HAL_PPP_MspInit() which will reconfigure the low level hardware.
