This sounds reasonable to me. I can prepare a v2. Any concerns regarding capabilities? For example data and data_end are only available to CAP_SYS_ADMIN. Note that enforcement of this would be done by a global component later in the pipeline (e.g., FQ qdisc). Any opinions on sk_filter, lwt, and sk_skb before I send v2?
