Don Lewis 883054b4c3 Change net.inet.tcp.ecn.enable sysctl mib from a binary off/on 
control to a three way setting.
  0 - Totally disable ECN. (no change)
  1 - Enable ECN if incoming connections request it.  Outgoing
      connections will request ECN.  (no change from present != 0 setting)
  2 - Enable ECN if incoming connections request it.  Outgoing
      conections will not request ECN.

Change the default value of net.inet.tcp.ecn.enable from 0 to 2.

Linux version 2.4.20 and newer, Solaris, and Mac OS X 10.5 and newer have
similar capabilities.  The actual values above match Linux, and the default
matches the current Linux default.
