 * Any increase in either ECT(0) or ECT(1) counts, plus any increase in the CE
   count, MUST be no smaller than the number of packets sent with the
   corresponding ECT codepoint that are newly acknowledged in this ACK frame.
   This step detects any erroneous network remarking from ECT(0) to ECT(1) (or
   vice versa).
 
+Processing ECN counts out of order can result in validation failure.  An
+endpoint SHOULD NOT perform this validation if this ACK frame does not advance
+the largest packet number acknowledged in this connection.

Connection scoped works for me, at least for now.  When we have a way to ACK packets on different paths at the same time, we can revisit this question.
