> 
> Many of the ethtool statistics use the same basic logic for copying strings into
> the supplied buffer. A set of stats are stored in a const array of i40e_stats
> structures, and we apply these all together.
> 
> Simplify the stats code by introducing a helper function which can take a stats
> array and copy the strings into the buffer, updating the buffer pointer as we
> go.
> 
> We use a macro to implement i40e_add_stat_strings so that ARRAY_SIZE can
> be used on the array passed in. This ensures that we always use the
> matching size in __i40e_add_stat_strings.
> 
> More complex stats currently do not use i40e_stats arrays, usually due to
> custom formatted strings, or because the stats are not laid out in the
> expected way. These stats will be updated to use the helper function in
> separate future patches.
