Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Reject invalid updates to netfilter expectation policies, from Pablo Neira Ayuso. 2) Fix memory leak in nfnl_cthelper, from Jeffy Chen. 3) Don't do stupid things if we get a neigh_probe() on a neigh entry whose ops lack a solicit method. From Eric Dumazet. 4) Don't transmit packets in r8152 driver when the carrier is off, from Hayes Wang. 5) Fix ipv6 packet type detection in aquantia driver, from Pavel Belous. 6) Don't write uninitialized data into hw registers in bna driver, from Arnd Bergmann. 7) Fix locking in ping_unhash(), from Eric Dumazet. 8) Make BPF verifier range checks able to understand certain sequences emitted by LLVM, from Alexei Starovoitov. 9) Fix use after free in ipconfig, from Mark Rutland. 10) Fix refcount leak on force commit in openvswitch, from Jarno Rajahalme. 11) Fix various overflow checks in AF_PACKET, from Andrey Konovalov. 12) Fix endianness bug in be2net driver, from Suresh Reddy. 13) Don't forget to wake TX queues when processing a timeout, from Grygorii Strashko. 14) ARP header on-stack storage is wrong in flow dissector, from Simon Horman. 15) Lost retransmit and reordering SNMP stats in TCP can be underreported. From Yuchung Cheng. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (82 commits) nfp: fix potential use after free on xdp prog tcp: fix reordering SNMP under-counting tcp: fix lost retransmit SNMP under-counting sctp: get sock from transport in sctp_transport_update_pmtu net: ethernet: ti: cpsw: fix race condition during open() l2tp: fix PPP pseudo-wire auto-loading bnx2x: fix spelling mistake in macros HW_INTERRUT_ASSERT_SET_* l2tp: take reference on sessions being dumped tcp: minimize false-positives on TCP/GRO check sctp: check for dst and pathmtu update in sctp_packet_config flow dissector: correct size of storage for ARP net: ethernet: ti: cpsw: wake tx queues on ndo_tx_timeout l2tp: take a reference on sessions used in genetlink handlers l2tp: hold session while sending creation notifications l2tp: fix duplicate session creation l2tp: ensure session can't get removed during pppol2tp_session_ioctl() l2tp: fix race in l2tp_recv_common() sctp: use right in and out stream cnt bpf: add various verifier test cases for self-tests bpf, verifier: fix rejection of unaligned access checks for map_value_adj ...
