The utility simply works with the current implementation (on both be and
le) and this is why changing the logic breaks it. I will look into it to
see if we can change the utility logic as well (maybe according to the
driver version) - it is not that easy since this utility supports other
drivers as well.

Harvey - thanks again for this patch, it is definitely a step in the
right direction.
