Subject: [Bloat] AQM and PPP on Linux
Date: Tue, 28 Jul 2015 15:09:14 +0200	[thread overview]
Message-ID: <87a8ugqvid.wl-jch@pps.univ-paris-diderot.fr> (raw)

I'm currently away from home, and using a 3G modem for Internet access.
I've found out that both NetworkManager and wvdial/pppd setup the
interface to use pfifo_fast (with a qlen of a mere 3 packets!).  Setting
fq_codel manually appears to work fine, but needs to be redone every time
the modem has a hiccup.

Is that the expected behaviour?  Shouldn't we be pushing patches somewhere
to change the default?
