Why overload the ECN bit this way? ECN should be used to indicate end-to-end congestion control compliance. In fact RFC 3168 requires that: "... the transport protocol must be capable of reacting appropriately to the receipt of CE packets." THat's independent of MTU discovery, or at least should be pointed out.
