Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "The pull requests are getting smaller, that's progress I suppose :-) 1) Fix infinite loop in CIPSO option parsing, from Yujuan Qi. 2) Fix remote checksum handling in VXLAN and GUE tunneling drivers, from Koichiro Den. 3) Missing u64_stats_init() calls in several drivers, from Florian Fainelli. 4) TCP can set the congestion window to an invalid ssthresh value after congestion window reductions, from Yuchung Cheng. 5) Fix BPF jit branch generation on s390, from Daniel Borkmann. 6) Correct MIPS ebpf JIT merge, from David Daney. 7) Correct byte order test in BPF test_verifier.c, from Daniel Borkmann. 8) Fix various crashes and leaks in ASIX driver, from Dean Jenkins. 9) Handle SCTP checksums properly in mlx4 driver, from Davide Caratti. 10) We can potentially enter tcp_connect() with a cached route already, due to fastopen, so we have to explicitly invalidate it. 11) skb_warn_bad_offload() can bark in legitimate situations, fix from Willem de Bruijn" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (52 commits) net: avoid skb_warn_bad_offload false positives on UFO qmi_wwan: fix NULL deref on disconnect ppp: fix xmit recursion detection on ppp channels rds: Reintroduce statistics counting tcp: fastopen: tcp_connect() must refresh the route net: sched: set xt_tgchk_param par.net properly in ipt_init_target net: dsa: mediatek: add adjust link support for user ports net/mlx4_en: don't set CHECKSUM_COMPLETE on SCTP packets qed: Fix a memory allocation failure test in 'qed_mcp_cmd_init()' hysdn: fix to a race condition in put_log_buffer s390/qeth: fix L3 next-hop in xmit qeth hdr asix: Fix small memory leak in ax88772_unbind() asix: Ensure asix_rx_fixup_info members are all reset asix: Add rx->ax_skb = NULL after usbnet_skb_return() bpf: fix selftest/bpf/test_pkt_md_access on s390x netvsc: fix race on sub channel creation bpf: fix byte order test in test_verifier xgene: Always get clk source, but ignore if it's missing for SGMII ports MIPS: Add missing file for eBPF JIT. bpf, s390: fix build for libbpf and selftest suite ...
