> A future patch is going to add a helper function i40e_add_ethtool_stats that

> This conversion will take place over many patches, and the helper function
> will work by directly updating a reference to the data pointer.
> Since this would not work combined with the current method of accessing
> data like an array, update all the code that copies stats into the data buffer to
> use direct updates to the pointer instead of array accesses.
> This will prevent incorrect stat updates for patches in between the
> Similarly, when copying strings, we used a separate char *p pointer.
> Instead, use the data pointer directly as it's already a (u8 *) type which is the
> same size.
