I am glad to see the rhine patches finally landed. There were a few popular devices used as firewalls that used that chipset.

Indeed there were (though I don't know if the Soekris net5501 I use could ever be defined as 'popular' except among the geekiest crowd and those who want to network up oil rigs.)

However I must note that your excellent result was probably due to fq_codel taking advantage of hardware flow control exerted by the DSL modem

That's what I presumed. Nothing else could explain how it managed to figure out my ADSL bandwidth given the total absence of any other way to detect it.

But nearly everybody put switches, rather than ethernet devices in the path here, over the past 5 years, and lost that capability.

Yeah. I guess if your modem has only one port, and you don't have a dedicated multi-port firewall box, that's all you can really do... I wonder: are the very common 'four-port ADSL modems' actually an ADSL modem and a switch in the same box? If so, I guess they're eschewing flow control too, right? :(

Thank you for a most excellent qdisc, anyway!
