+ * Notification (ECN) field (2 bits). The DSCP field is typically used to

+ * to be leveraged by transport layer protocols such as TCP and SCTP that have

+ *
+ * When congestion is experienced, as alternative to dropping the packet,

+ * (values indicating that source endpoint is ECN-capable) to 2'b11 (meaning
+ * that congestion is experienced). The destination endpoint can use the
+ * ECN-Echo (ECE) TCP flag to relay the congestion indication back to the
+ * source endpoint, which acknowledges it back to the destination endpoint with
+ * the Congestion Window Reduced (CWR) TCP flag.
+ *
+ * All IPv4/IPv6 packets of a given color with ECN set to 2’b01 or 2’b10
+ * carrying TCP or SCTP have their ECN set to 2’b11 if the marking feature is
+ * enabled for the current color, otherwise the ECN field is left as is.
