Pull networking fixes from David Miller:

 1) Brown paper bag fix in HTB scheduler, class options set incorrectly
    due to a typoe.  Fix from Vimalkumar.

 2) It's possible for the ipv6 FIB garbage collector to run before all
    the necessary datastructure are setup during init, defer the
    notifier registry to avoid this problem.  Fix from Michal Kubecek.

 3) New i40e ethernet driver from the Intel folks.

 4) Add new qmi wwan device IDs, from Bjørn Mork.

 5) Doorbell lock in bnx2x driver is not initialized properly in some
    configurations, fix from Ariel Elior.

 6) Revert an ipv6 packet option padding change that broke standardized
    ipv6 implementation test suites.  From Jiri Pirko.

 7) Fix synchronization of ARP information in bonding layer, from
    Nikolay Aleksandrov.

 8) Fix missing error return resulting in illegal memory accesses in
    openvswitch, from Daniel Borkmann.

 9) SCTP doesn't signal poll events properly due to mistaken operator
    precedence, fix also from Daniel Borkmann.

10) __netdev_pick_tx() passes wrong index to sk_tx_queue_set() which
    essentially disables caching of TX queue in sockets :-/ Fix from
    Eric Dumazet.
