If these are changed when forwarding, two issues may be encountered: - If "show config fwd" is used, changes made in the core list are applied. Therefore, trying to stop forwarding may hang testpmd, since it could be waiting for cores to stop that are not actually running anything - If the port list is changed, when stopping forwarding, it may miss the stats of some of the ports that were actually being used.
