Yes, that exactly. I was thinking about the most optimal algorithm, but
such would need to consider speeds between links too. For example the
DSA port between two switches can be linked at 1 GB, but cpu can be
connected to switch with 2.5G. What assignment is best in that case?
I think that we should try to solve such issue when it arises, if ever.
Such cases are more reason to add the ability to change cpu ports for
given ports.
