====================
pull request (net): ipsec 2018-01-24

1) Only offloads SAs after they are fully initialized.
   Otherwise a NIC may receive packets on a SA we can
   not yet handle in the stack.
   From Yossi Kuperman.

2) Fix negative refcount in case of a failing offload.
   From Aviad Yehezkel.

3) Fix inner IP ptoro version when decapsulating
   from interaddress family tunnels.
   From Yossi Kuperman.

4) Use true or false for boolean variables instead of an
   integer value in xfrm_get_type_offload.
   From Gustavo A. R. Silva.
