Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf
Daniel Borkmann says: ==================== pull-request: bpf 2018-08-05 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Fix bpftool percpu_array dump by using correct roundup to next multiple of 8 for the value size, from Yonghong. 2) Fix in AF_XDP's __xsk_rcv_zc() to not returning frames back to allocator since driver will recycle frame anyway in case of an error, from Jakub. 3) Fix up BPF test_lwt_seg6local test cases to final iproute2 syntax, from Mathieu. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
