xfrm: set skb control buffer based on packet offload as well
In packet offload, packets are not encrypted in XFRM stack, so the next network layer which the packets will be forwarded to should depend on where the packet came from (either xfrm4_output or xfrm6_output) rather than the matched SA's family type. Test: verified IPv6-in-IPv4 packets on Android device with IPsec packet offload enabled Signed-off-by: Mike Yu <yumike@google.com> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
