Subject: [PATCH net-next 0/7] net: stmmac: Improve default addend/subsecond
 increment readability

This series aims to improve the readability of the calculations
for the default addend and subsecond increment values.

I recently had to understand what the hardware did by reading this code,
and it took me longer than I care to admit. These patches aim to make it
more self explanatory.

Suggestions to further improve this are very welcomed.
