xfrm: Provide private skb extensions for segmented and hw offloaded E…
…SP packets [ Upstream commit c7dbf4c ] Commit 94579ac ("xfrm: Fix double ESP trailer insertion in IPsec crypto offload.") added a XFRM_XMIT flag to avoid duplicate ESP trailer insertion on HW offload. This flag is set on the secpath that is shared amongst segments. This lead to a situation where some segments are not transformed correctly when segmentation happens at layer 3. Fix this by using private skb extensions for segmented and hw offloaded ESP packets. Fixes: 94579ac ("xfrm: Fix double ESP trailer insertion in IPsec crypto offload.")
