[CentOS] Traffic shaping on CentOS

I came across this on the Fedora devel list. I added 
/etc/sysctl.d/51-bufferbloat.conf containing the suggested line and it 
installs the new codel qdisc as desired. There's probably more knobs that 
might be useful to tweak but this makes a good start. More reading on the 
bufferbloat site suggests that the later "cake" module will be even better, 
but it requires a newer kernel than CentOS currently ships with.


# 51-bufferbloat.conf
# Address bufferbloat
net.core.default_qdisc = fq_codel
