Hey, point taken. I'm just pointing out what I've seen in real life and
how it leads to crappy perceived performance on those little 8xx series
routers and their connected bandwidth.

I see a lot of them with straight FIFO/taildrop on their DSL interfaces
and then people wonder why a few uploads cause their browsing, VPNs, etc,
to fail.

I can't see whats going on with the 871 because, well, I don't think I've
seen its config. :)
