I'm not following you.  You can only perform ECN marking when you detect
congestion; and you can only detect congestion if you're queueing.
I may be wrong, but I believe that HTB doesn't do any queueing itself,
it delegates queuing to its child qdiscs; hence, I don't see how you can
perform ECN marking in HTB itself; you should be doing it in HTB's child

I'm not sure I understand that.
