Subject: pull request (net-next): ipsec-next 2017-02-01

1) Some typo fixes, from Alexander Alemayhu.

2) Don't acquire state lock in get_mtu functions.
   The only rece against a dead state does not matter.
   From Florian Westphal.

3) Remove xfrm4_state_fini, it is unused for more than
   10 years. From Florian Westphal.

4) Various rcu usage improvements. From Florian Westphal.

5) Properly handle crypto arrors in ah4/ah6.
   From Gilad Ben-Yossef.

6) Try to avoid skb linearization in esp4 and esp6.

7) The esp trailer is now set up in different places,
   add a helper for this.

8) With the upcomming usage of gro_cells in IPsec,
   a gro merged skb can have a secpath. Drop it
   before freeing or reusing the skb.

9) Add a xfrm dummy network device for napi. With
   this we can use gro_cells from within xfrm,
   it allows IPsec GRO without impact on the generic
   networking code.

Please pull or let me know if there are problems.

Thanks!
