      Pull networking updates from David Miller:
       "Most notable changes in here:
         1) By far the biggest accomplishment, thanks to a large range of
            contributors, is the addition of multi-send for transmit.  This is
            the result of discussions back in Chicago, and the hard work of
            several individuals.
            Now, when the ->ndo_start_xmit() method of a driver sees
            skb->xmit_more as true, it can choose to defer the doorbell
            telling the driver to start processing the new TX queue entires.
            skb->xmit_more means that the generic networking is guaranteed to
            call the driver immediately with another SKB to send.
            There is logic added to the qdisc layer to dequeue multiple
            packets at a time, and the handling mis-predicted offloads in
            software is now done with no locks held.
            Finally, pktgen is extended to have a "burst" parameter that can
            be used to test a multi-send implementation.
            Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
            Adding support is almost trivial, so export more drivers to
            support this optimization soon.
            I want to thank, in no particular or implied order, Jesper
            Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
            Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
            David Tat, Hannes Frederic Sowa, and Rusty Russell.
         2) PTP and timestamping support in bnx2x, from Michal Kalderon.
         3) Allow adjusting the rx_copybreak threshold for a driver via
            ethtool, and add rx_copybreak support to enic driver.  From
            Govindarajulu Varadarajan.
         4) Significant enhancements to the generic PHY layer and the bcm7xxx
            driver in particular (EEE support, auto power down, etc.) from
            Florian Fainelli.
         5) Allow raw buffers to be used for flow dissection, allowing drivers
            to determine the optimal "linear pull" size for devices that DMA
            into pools of pages.  The objective is to get exactly the
            necessary amount of headers into the linear SKB area pre-pulled,
            but no more.  The new interface drivers use is eth_get_headlen().
            From WANG Cong, with driver conversions (several had their own
            by-hand duplicated implementations) by Alexander Duyck and Eric
         6) Support checksumming more smoothly and efficiently for
            encapsulations, and add "foo over UDP" facility.  From Tom
         7) Add Broadcom SF2 switch driver to DSA layer, from Florian
         8) eBPF now can load programs via a system call and has an extensive
            testsuite.  Alexei Starovoitov and Daniel Borkmann.
         9) Major overhaul of the packet scheduler to use RCU in several major
            areas such as the classifiers and rate estimators.  From John
        10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
        11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
        12) Add Datacenter TCP congestion control algorithm support, From
            Florian Westphal.
        13) Reorganize sk_buff so that __copy_skb_header() is significantly
            faster.  From Eric Dumazet"

       "Starting with 3.18, we are merging SoC-specific changes for arm64
        through the arm-soc tree, like we have been doing for arm32.
        This time, there is only one set of changes, adding support for the
        Cavium "Thunder" Soc family.  Since the changes are relatively small,
        this includes Kconfig, defconfig and DT changes.

      Pull ARM SoC driver updates from Arnd Bergmann:
       "These are changes for drivers that are intimately tied to some SoC and
        for some reason could not get merged through the respective subsystem

        Most of the new code is for the Keystone Navigator driver, which is
        new base support that is going to be needed for their hardware
        accelerated network driver and other units.
        Most of the commits are for moving old code around from at91 and omap

      cxgb4: clean up a type issue · fb5ac0de
      Dan Carpenter authored
      The tx_desc struct holds 8 __be64 values.  The original code in
      ring_tx_db() took a tx_desc pointer then casted it to an int pointer and
      then casted it to a u64 pointer.  It was confusing and triggered some
      static checker warnings.
      I have changed the cxgb_pio_copy() function to only take tx_desc
      pointers.  This isn't really a loss of flexibility because anything else
      was buggy to begin with.
      I also removed the casting on the destination pointer since that was
      unnecessary and a bit messy.

      Christophe Leroy says:
      net: fs_enet: Remove non NAPI RX and add NAPI for TX
      When using a MPC8xx as a router, 'perf' shows a significant time spent in
      fs_enet_interrupt() and fs_enet_start_xmit().
      'perf annotate' shows that the time spent in fs_enet_start_xmit is indeed spent
      between spin_unlock_irqrestore() and the following instruction, hence in
      interrupt handling. This is due to the TX complete interrupt that fires after
      each transmitted packet.
      This patchset first remove all non NAPI handling as NAPI has become the only
      mode for RX, then adds NAPI for handling TX complete.
      This improves NAT TCP throughput by 21% on MPC885 with FEC.
      Tested on MPC885 with FEC.

      r8169:add support for RTL8168EP · 935e2218
      Chun-Hao Lin authored
      RTL8168EP is Realtek PCIe Gigabit Ethernet controller with DASH support.
      It is a successor chip of RTL8168DP.
      For RTL8168EP, the read/write ocp register is via eri channel type 2, so I
      move ocp_xxx() related functions under rtl_eri_xxx. And use r8168dp_ocp_xxx()
      for RTL8168DP ocp read/write, r8168ep_ocp_xxx() for RTL8168EP ocp read/write.
      The way of checking dash enable is different with RTL8168DP. I use
      r8168dp_check_dash()for RTL8168DP and r8168ep_check_dash() for RTL8168EP,
      to check if dash is enabled.
      The driver_start() and driver_stop() of RTL8168EP is also different with
      RTL8168DP. I use rtl8168dp_driver_xxx() for RTL8168DP and
      rtl8168ep_driver_xxx for RTL8168EP.
      Right now, RTL8168EP phy mcu did not need firmware code patch, so I did not
      add firmware code for it.

       "Here is the big staging patch set for 3.18-rc1.
        Once again, we are deleting more code than we added, with something
        like 150000 lines deleted overall.  Some of this is due to drivers
        being added to the networking tree, so the old versions are removed
        here, but even then, the overall difference is quite good.
        Other than driver deletions, lots and lots and lots of minor cleanups
        all over the place.  Full details are in the changelog"
