For ECNs that are already part of the PCIe Base Spec, it's better to cite the section in the latest spec revision, i.e. PCIe r7.0 sec 6.35, rather than the ECN that originally introduced the feature. Reviewers (like me) generally have the latest spec revision at hand, but not every ECN. Otherwise this is Reviewed-by: Lukas Wunner
