Pull networking fixes from David Miller:

 1) Fix out-of-bounds array access in netfilter ipset, from Jozsef
    Kadlecsik.

 2) Use correct free operation on netfilter conntrack templates, from
    Daniel Borkmann.

 3) Fix route leak in SCTP, from Marcelo Ricardo Leitner.

 4) Fix sizeof(pointer) in mac80211, from Thierry Reding.

 5) Fix cache pointer comparison in ip6mr leading to missed unlock of
    mrt_lock.  From Richard Laing.

 6) rds_conn_lookup() needs to consider network namespace in key
    comparison, from Sowmini Varadhan.

 7) Fix deadlock in TIPC code wrt broadcast link wakeups, from Kolmakov
    Dmitriy.

 8) Fix fd leaks in bpf syscall, from Daniel Borkmann.

 9) Fix error recovery when installing ipv6 multipath routes, we would
    delete the old route before we would know if we could fully commit
    to the new set of nexthops.  Fix from Roopa Prabhu.

10) Fix run-time suspend problems in r8152, from Hayes Wang.

11) In fec, don't program the MAC address into the chip when the clocks
    are gated off.  From Fugang Duan.

12) Fix poll behavior for netlink sockets when using rx ring mmap, from
    Daniel Borkmann.

13) Don't allocate memory with GFP_KERNEL from get_stats64 in r8169
    driver, from Corinna Vinschen.

14) In TCP Cubic congestion control, handle idle periods better where we
    are application limited, in order to keep cwnd from growing out of
    control.  From Eric Dumzet.
