Hi; I have been reading code in order to understand how relations between kernel and user-space is working. But I do not understand how this rtattr struct work. What I would like to know is how I can send a message in user-space and parse this data in kernel. Function rtattr_parse, rta_payload and rta_data is what I have seen cbq and the rest of the queuing mechanism are using. I would be thankful if anyone could explain to a novice how this work.
