This optional normative ECN defines an End-End TLP Prefix for conveying additional attributes associated with a request. The PASID TLP Prefix is an End-End TLP Prefix as defined in the PCI Express Base Specification. Routing elements that support End-End TLP Prefixes (i.e. have the End-End TLP Prefix Supported bit Set in the Device Capabilities 2 register) can correctly forward TLPs containing a PASID TLP Prefix.
