Uhm, it was so easy ;)
part of my python script now
os.system("tc qdisc del root dev %s 2> /dev/null" % ppp_iface)
os.system("tc qdisc del dev %s ingress 2> /dev/null" % ppp_iface)
# downstream
os.system("tc qdisc add dev %s root tbf rate %skbit latency 50ms burst 1540"
% (ppp_iface, speed_down))
# upstream
os.system("tc qdisc add dev %s handle ffff: ingress" % ppp_iface)
os.system("tc filter add dev %s parent ffff: protocol ip prio 50 u32 match ip src 0.0.0.0/0 police rate %skbit burst 10k drop flowid :1" % (ppp_iface, speed_up))
