View FQ_Codel Traffic Shaper Statistics

[joysense]

Are there any commands in ipfw to view fq_codel statistics / usage?
1. I Want  to see number of active flows.
2. I want to see dropped statistics.
3. I want to see average/mean queue delay.

Any plugins/ ipfw cli commands to view this? Feel free to attach any useful links. I would like to read more if I have to figure this one out.
