Control use of Explicit Congestion Notification (ECN) by SCTP.
Like in TCP, ECN is used only when both ends of the SCTP connection
indicate support for it. This feature is useful in avoiding losses
due to congestion by allowing supporting routers to signal congestion
before having to drop packets.
1: Enable ecn.
0: Disable ecn.
