But what _is_ a good path to fix the BitTorrent problem[1]? I still haven't
seen a real-life practical solution. LEDBAT is negated by fq_codel, DSCP
markings don't work (they get stripped, and usually were not even set to
begin with), switching to IP-level fairness makes life hard for the torrent
user (not that it seems to even exist in fq_codel; and two-level fq_codel
doesn't seem to exist either). DPI to single out torrent traffic? I think
we've sort of tried that. :-)

[1] For the purposes of the question, the “BitTorrent problem” is when you
and I are on the same network, and your 200+ BitTorrent upload sessions
makes it impossible for me to upload my single cat video to YouTube.
