1) Handle NETDEV_UNREGISTER for xfrm device to handle asynchronous
   unregister events cleanly. From Raed Salem.

2) Fix vti6 tunnel inter address family TX through bpf_redirect().
   From Nicolas Dichtel.

3) Fix lenght check in verify_sec_ctx_len() to avoid a
   slab-out-of-bounds. From Xin Long.

4) Add a missing verify_sec_ctx_len check in xfrm_add_acquire
   to avoid a possible out-of-bounds to access. From Xin Long.

5) Use built-in RCU list checking of hlist_for_each_entry_rcu
   to silence false lockdep warning in __xfrm6_tunnel_spi_lookup
   when CONFIG_PROVE_RCU_LIST is enabled. From Madhuparna Bhowmik.

6) Fix a panic on esp offload when crypto is done asynchronously.
   From Xin Long.

7) Fix a skb memory leak in an error path of vti6_rcv.
   From Torsten Hilbrich.

   From Xin Long.

Please pull or let me know if there are problems.

Thanks!
