net: flow_dissector: add __skb_get_poff to get a start offset to payload __skb_get_poff() returns the offset to the payload as far as it could be dissected. The main user is currently BPF, so that we can dynamically truncate packets without needing to push actual payload to the user space and instead can analyze headers only.
