Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix races in IPVS, from Tan Hu. 2) Missing unbind in matchall classifier, from Hangbin Liu. 3) Missing act_ife action release, from Vlad Buslov. 4) Cure lockdep splats in ila, from Cong Wang. 5) veth queue leak on link delete, from Toshiaki Makita. 6) Disable isdn's IIOCDBGVAR ioctl, it exposes kernel addresses. From Kees Cook. 7) RCU usage fixup in XDP, from Tariq Toukan. 8) Two TCP ULP fixes from Daniel Borkmann. 9) r8169 needs REALTEK_PHY as a Kconfig dependency, from Heiner Kallweit. 10) Always take tcf_lock with BH disabled, otherwise we can deadlock with rate estimator code paths. From Vlad Buslov. 11) Don't use MSI-X on RTL8106e r8169 chips, they don't resume properly. From Jian-Hong Pan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (41 commits) ip6_vti: fix creating fallback tunnel device for vti6 ip_vti: fix a null pointer deferrence when create vti fallback tunnel r8169: don't use MSI-X on RTL8106e net: lan743x_ptp: convert to ktime_get_clocktai_ts64 net: sched: always disable bh when taking tcf_lock ip6_vti: simplify stats handling in vti6_xmit bpf: fix redirect to map under tail calls r8169: add missing Kconfig dependency tools/bpf: fix bpf selftest test_cgroup_storage failure bpf, sockmap: fix sock_map_ctx_update_elem race with exist/noexist bpf, sockmap: fix map elem deletion race with smap_stop_sock bpf, sockmap: fix leakage of smap_psock_map_entry tcp, ulp: fix leftover icsk_ulp_ops preventing sock from reattach tcp, ulp: add alias for all ulp modules bpf: fix a rcu usage warning in bpf_prog_array_copy_core() samples/bpf: all XDP samples should unload xdp/bpf prog on SIGTERM net/xdp: Fix suspicious RCU usage warning net/mlx5e: Delete unneeded function argument Documentation: networking: ti-cpsw: correct cbs parameters for Eth1 100Mb isdn: Disable IIOCDBGVAR ...
