pull-request: bpf-next 2018-09-01

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Add AF_XDP zero-copy support for i40e driver (!), from Björn and Magnus.

2) BPF verifier improvements by giving each register its own liveness
   chain which allows to simplify and getting rid of skip_callee() logic,
   from Edward.

3) Add bpf fs pretty print support for percpu arraymap, percpu hashmap
   and percpu lru hashmap. Also add generic percpu formatted print on
   bpftool so the same can be dumped there, from Yonghong.

4) Add bpf_{set,get}sockopt() helper support for TCP_SAVE_SYN and
   TCP_SAVED_SYN options to allow reflection of tos/tclass from received
   SYN packet, from Nikita.

5) Misc improvements to the BPF sockmap test cases in terms of cgroup v2
   interaction and removal of incorrect shutdown() calls, from John.

6) Few cleanups in xdp_umem_assign_dev() and xdpsock samples, from Prashant.
