Good point! For HW drops we get an SKB and relevant metadata from devlink about why the packet was dropped etc. I plan to store a pointer to this metadata in the SKB control block. Let me see how the implementation goes. Even if use sk_buff_head for now, I will make sure that converting to a more generalized data structure is straightforward.
