-If a path has been verified to support ECN, QUIC treats a Congestion Experienced
-codepoint in the IP header as a signal of congestion. This document specifies an
-endpoint's response when its peer receives packets with the Congestion
-Experienced codepoint.  As discussed in {{!RFC8311}}, endpoints are permitted to
-experiment with other response functions.
