parentnet: Add a xfrm validate function to validate_xmit_skb (diff)
xfrm: Add encapsulation header offsets while SKB is not encrypted
Both esp4 and esp6 used to assume that the SKB payload is encrypted and therefore the inner_network and inner_transport offsets are not relevant. When doing crypto offload in the NIC, this is no longer the case and the NIC driver needs these offsets so it can do TX TCP checksum offloading. This patch sets the inner_network and inner_transport members of the SKB, as well as encapsulation, to reflect the actual positions of these headers, and removes them only once encryption is done on the payload.
