Steffen Klassert says:

====================
pull request (net-next): ipsec-next 2018-03-29

1) Remove a redundant pointer initialization esp_input_set_header().
   From Colin Ian King.

2) Mark the xfrm kmem_caches as __ro_after_init.
   From Alexey Dobriyan.

3) Do the checksum for an ipsec offlad packet in software
   if the device does not advertise NETIF_F_HW_ESP_TX_CSUM.
   From Shannon Nelson.

4) Use booleans for true and false instead of integers
   in xfrm_policy_cache_flush().
   From Gustavo A. R. Silva

Please pull or let me know if there are problems.
