[Gllug] Barclays routers don't support ECN

[Rev Simon Rumble]

I've been banging my head against this strange problem with the
Barclays web site.  It just wouldn't fscking work, yet every other
site on the net did.

simon at chimay:~$ telnet www.barclays.co.uk 80
Trying 193.128.3.187...
Trying 62.172.239.187...
telnet: Unable to connect to remote host: Connection timed out

Finally I had a brain wave and remembered I'd turned ECN on.  I
haven't noticed any other problem sites, but it appears Barclays have
old crappy router firmware...

To turn off ECN, you either set the kernel option to "no" (the
default) or do this:

echo 0 > /proc/sys/net/ipv4/tcp_ecn

If you're a Barclays customer, you might want to log a support call
asking them to upgrade their routers.
