[SK_BUFF]: More skb_reset_transport_header conversions
These are a bit more subtle, they are of this type: - skb->h.raw = payload; __skb_pull(skb, payload - skb->data); + skb_reset_transport_header(skb); __skb_pull results in: skb->data = skb->data + payload - skb->data; skb->data = payload; So after __skb_pull we have skb->data pointing to payload and we can just call skb_reset_transport_header(skb), that will do: skb->h.raw = payload; The others are similar, allowing us to get rid of some more cases where a pointer was being attributed to the layer headers.
