Conformance test results DestinationPortMatching and ParentRefPort are confusing #4302
Description
What would you like to be added:
Explanation of what is covered by a conformance test, and/or link to the GEP the conformance test is supposed to cover
Why this is needed:
After spending quite some time trying to figure out the difference between DestinationPortMatching and ParentRefPort I am coming to the conclusion that these features seem to be about the same feature? There is a GEP mentioning destination port matching, which clearly describes the parent ref port as the chosen solution. However the results are not the same for all implementations, possibly because implementations are also not clear that these are the same feature so don't list them as supported in their conformance tests which I think skips testing the feature.
Or all of the above is wrong, which would further add to my point that the conformance tests and what they cover are unclear.
