This is the first part of patchset [1] containing only the fixes for the
link BW and DSC slice computation. The remaining patches in [1] refactor
the link BW and DSC slice computation simplifying these, to be sent as a
follow-up to this patchset.

I moved patches 13-15 in [1] later in the patchset to be sent as part of
the follow-up, as these patches are not a dependency for the fixes in
this patchset.
