Hello, section 15.1 of 2.4routing-howto talks about bfifo and pfifo qdiscs. Do they work? # ip l l ... 2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100 ... # tc qdisc add dev eth0 bfifo RTNETLINK answers: Invalid argument What do I miss? Kernel (2.2.19) has every NET_SCH_ option activated (module).
