As hinted in a previous message -- please don't. Every qdisc must be
examined individually to check if it is suitable for ECN.
Consider also the following. If the administrator specifies a maximum
rate of 100 Mbit/s, he probably doesn't expect the outgoing traffic to
exceed that rate under any circumstances. If you start marking instead
of dropping, you must make sure that the resulting traffic is still
under 100 Mbit/s, including the marked packets.
