sysctl.d: default to fq_codel, fight bufferbloat
Quoting from Jon Corbet's report of Stephen Hemminger's talk at Linux Plumbers Conference 2014 (https://lwn.net/Articles/616241/): [...] So Stephen encouraged everybody to run a command like: sysctl -w net.core.default_qdisc=fq_codel That will cause fq_codel to be used for all future connections [Qdiscs apply to interfaces, not connections. Pointed out by TomH in the article comments. -- mschmidt] (up to the next reboot). Unfortunately, the default queuing discipline cannot be changed, since it will certainly disturb some user's workload somewhere. Let's have the recommended default in systemd. Thanks to Dave Täht for advice and the summary at https://lists.bufferbloat.net/pipermail/cerowrt-devel/2014-October/003701.html
