Another example - Same thing happened with ECN. I recall setting up a mail
server at the time and noticing that I had to disable ECN because some
dumbass PIX routers out there were dropping packets with a _reserved bit_
set! Sure, there was a firmware upgrade, but the dingbat admins I tried to
alert didn't seem (at the time) too interested in fixing their problem.

Does anyone have any interesting statistics on how often end-users are
likely to run into this crap? It really is a shame when you have to suck just
because someone else does.
