[[ Sorry for the Double Send: I forgot to switch to Plain Text. Have I mentioned how much I hate modern Web-based email agents? :-) -- Casey ]] Yeah, I think this works for now. We'll stumble over what to do when we want to mix upstream TLPs without Relaxed Ordering Attributes directed at problematic Root Complexes, and Peer-to-Peer TLPs with Relaxed Ordering Attributes ... or vice versa depending on which target PCIe Device has issues with Relaxed Ordering.
