What is "flowid"?
Illegal "police"
ERROR: Command "tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match ip src 0.0.0.0/0 police rate 500kbps burst 10k drop flowid :1" Failed

FIX:

Enter root:

sudo -i

Install tools:

apt-get install build-essential fakeroot devscripts

Make a working directory:

mkdir /tmp/iproutefix && cd /tmp/iproutefix

Download DebDiff:

wget http://launchpadlibrarian.net/15355596/iproute_20071016-2ubuntu2.debdiff

Get the package source tree:

apt-get source iproute

Install libraries needed to build the source package:

apt-get build-dep -y iproute
