Whoops.

CONFIG_INET_ECN:                                                        x   
  x                                                                         x   
  x Explicit Congestion Notification (ECN) allows routers to notify         x   
  x clients about network congestion, resulting in fewer dropped packets    x   
  x and increased network performance. This option adds ECN support to the  x   
  x Linux kernel, as well as a sysctl (/proc/sys/net/ipv4/tcp_ecn) which    x   
  x allows ECN support to be disabled at runtime.                           x   
  x                                                                         x   
  x Note that, on the Internet, there are many broken firewalls which       x   
  x refuse connections from ECN-enabled machines, and it may be a while     x   
  x before these firewalls are fixed. Until then, to access a site behind   x   
  x such a firewall (some of which are major sites, at the time of this     x   
  x writing) you will have to disable this option, either by saying N now   x   
  x or by using the sysctl.                                                 x   
  x                                                                         x   
  x If in doubt, say N.
