Mike Kolesnik has submitted this change and it was merged. Change subject: core: util for removing overlaps in ranges ...................................................................... core: util for removing overlaps in ranges user defined MacPool ranges can contain overlaps. Previously this was handled by adding each MAC from each mac range into HashSet. This was inefficient and can cause lot of MACs being initialized pointlessly. This util takes N ranges and transform it into M ranges (M<=N) where are no overlaps.
