There are 3 cases: - when HW can't implement at all the functionality. - when HW can implement a part of the functionality but needs the SW implement the rest. For example if it can't detect when it stops receiving MRP Test frames but it can copy the MRP frames to CPU to allow the SW to determin this. Another example is generating the MRP Test frames. If HW can't do that then the SW is used as backup. - when HW can implement completely the functionality. So, initially the SW tries to offload the entire functionality in HW, if that fails it tries offload parts of the functionality in HW and use the SW as helper and if also this fails then MRP can't run on this HW.
