[problem] qdisc_change() from net/sched/sch_api.c

[Gery Kahn <geryk@sphera.com>]

This is happened in 2.2.19
When i am calling
	tc qdisc change dev eth0 handle 1: root cbq bandwidth 50Mbit avpkt
1000
gets error 
RTNETLINK answer: Invalid argument
I found that in function qdisc_change() follow code executes:
	if (sch->ops->change == NULL)
                        return -EINVAL;
Well.
Is there any explanation or fix or workaround?
Please help.
