tc 
This is a work in progress version of tc. It provides a C-binding free API to the netlink based traffic control system of rtnetlink.
Example
func main() {
// open a rtnetlink socket
rtnl, err := tc.Open(&tc.Config{})
if err != nil {
fmt.Fprintf(os.Stderr, "could not open rtnetlink socket: %v\n", err)
return
}
defer func() {
if err := rtnl.Close(); err != nil {
fmt.Fprintf(os.Stderr, "could not close rtnetlink socket: %v\n", err)
}
}()
// get all the qdiscs from all interfaces
qdiscs, err := rtnl.Qdisc().Get()
if err != nil {
fmt.Fprintf(os.Stderr, "could not get qdiscs: %v\n", err)
return
}
for _, qdisc := range qdiscs {
iface, err := net.InterfaceByIndex(int(qdisc.Ifindex))
if err != nil {
fmt.Fprintf(os.Stderr, "could not get interface from id %d: %v", qdisc.Ifindex, err)
return
}
fmt.Printf("%20s\t%s\n", iface.Name, qdisc.Kind)
}
