Hi, I have set up QoS using HTB to identify classes and SFQ to order all classes traffic. It work fine but sometime "strange" paquets are sent... They contains correct data but headers seams to be truncated: has if the FIRST few bits were lost, or some alignment problem... It doesn't occure if using other queue than SFQ. It appends with 2.4.20 and 2.4.21. Any idea ?
