On Linux 3.13 and later it's easier to just add fq or fq_codel to /etc/sysctl.conf, which will enable it for all your devices, including those with hardware multi-queues. Or, at the command line: sysctl -w net.core.default_qdisc=fq # if you are a host sysctl -w net.core.default_qdisc=fq_codel # if you are a router (but this requires that each interface be taken up and down. Better to just stick it in sysctl.conf and forget about it)
