Interesting. I just enabled this on my machines. Is there a way to find out whether ECN has been successfully negotiated?

  I don't see it in netstat -s. Possibly you'd have to hack up a netfilter rule.

    Or you can test negotiation towards a particular host using this patched scamper, a traceroute-like tool: http://test-ecn.csail.mit.edu/ http://test-ecn.csail.mit.edu/
