When creating Port Pair Groups, the associated Port Pairs should all share the same correlation type. If not, the instances of each group will require different processing and will not be able to provide the same set of features at the respective hop of the chain, e.g. not able to fully encapsulate the packets (which could lead to chain packet leakage) or not able to transport metadata, amongst other reasons. Ideally, it should be possible to clearly state what is supported, and how, per each hop of a chain (independently of what instances are associated to that hop/PPG).
Currently, the OVS driver works around this by falling back to having no correlation at the next hops, if at least one of the PPs/next hops doesn't support the correlation required by the Port Chain.
