====================
Netfilter fixes for net-next

This batch contains two fixes for what you have in your net-next,
they are:

1) Remove nf_send_reset6() from header file. This function now resides
   in the nf_reject_ipv6 module. Reported by Eric Dumazet.

2) Fix wrong NFT_REJECT_ICMPX_MAX definition and adjust code to fix
   errors reported by Dan Carpenter's static analysis tools.

John W. Linville says:

====================
pull request: wireless-next 2014-10-09

Please pull this batch of fixes intended for the 3.18 stream!

Andrea Merello makes rtl818x_pci use a more reasonable transmission
rate for HW generated frames.

Fabian Frederick tweaks some kernel-doc bits to avoid warnings.

Larry Finger corrects a possible unaligned access in the rtlwifi code.

Marek Puzyniak avoids a kernel panic in ath9k_hw_reset.

Sujith Manoharan goes for the hat trick -- he fixes a smatch warning
in the shared ath code, he fixes a crash in ath9k, and he corrects
a sequence number assignment problem in ath9k too.

For ease of merging, I pulled the last bits of the wireless tree as well...

Please let me know if there are problems!

b8358d70ce net_sched: restore qdisc quota fairness limits after bulk dequeue
Restore the quota fairness between qdisc's, that we broke with commit
5772e9a346 ("qdisc: bulk dequeue support for qdiscs with TCQ_F_ONETXQUEUE").

Before that commit, the quota in __qdisc_run() were in packets as
dequeue_skb() would only dequeue a single packet, that assumption
broke with bulk dequeue.

We choose not to account for the number of packets inside the TSO/GSO
packets (accessable via "skb_gso_segs").  As the previous fairness
also had this "defect". Thus, GSO/TSO packets counts as a single
packet.

Further more, we choose to slack on accuracy, by allowing a bulk
dequeue try_bulk_dequeue_skb() to exceed the "packets" limit, only
limited by the BQL bytelimit.  This is done because BQL prefers to get
its full budget for appropriate feedback from TX completion.

In future, we might consider reworking this further and, if it allows,
switch to a time-based model, as suggested by Eric. Right now, we only
restore old semantics.

Joint work with Eric, Hannes, Daniel and Jesper.  Hannes wrote the
first patch in cooperation with Daniel and Jesper.  Eric rewrote the
patch.

====================
gianfar: ARM port driver updates (1/2)

This is the first round of driver portability fixes and clean-up
with the main purpose to make gianfar portable on ARM, for the ARM
based SoC that integrates the eTSEC ethernet controller - "ls1021a".
The patches primarily address compile time errors, when compiling
gianfar on ARM.  They replace PPC specific functions and macros
with architecture independent ones, solve arch specific header
inclusions, guard code that relates to PPC only, and even address
some simple endianess issues (see MAC address setup patch).
The patches addressing the bulk of remaining endianess issues,
like handling DMA fields (BD and FCB), will follow with the second
round.

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,
      virtio_net

      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
      Dumazet.

   6) Support checksumming more smoothly and efficiently for
      encapsulations, and add "foo over UDP" facility.  From Tom
      Herbert.

   7) Add Broadcom SF2 switch driver to DSA layer, from Florian
      Fainelli.

   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
      Fastabend.

  10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
      Duyck.

  11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
      Dumazet.

  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"

d5935b07da ARM64: SoC changes for 3.18
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.
 
 If all goes well, we will never require adding actual C source code
 for platform support in arm64, given that the architecture is more
 clearly defined and we have moved out a lot of the platform specifics
 into device drivers for arm32 already.

Pull ARM64 SoC changes from Arnd Bergmann:
 "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.

  If all goes well, we will never require adding actual C source code
  for platform support in arm64, given that the architecture is more
  clearly defined and we have moved out a lot of the platform specifics
  into device drivers for arm32 already"

8b45bc892e ARM: SoC driver updates for 3.18
These are changes for drivers that are intimately tied to some SoC
 and for some reason could not get merged through the respective
 subsystem maintainer tree.
 
 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
 for things that are done in device drivers nowadays.
 
 - at91: move reset, poweroff, memory and clocksource code into drivers
   directories
 - socfpga: add edac driver (through arm-soc, as requested by Boris)
 - omap: move omap-intc code to drivers/irqchip
 - sunxi: added an RTC driver for sun6i
 - omap: mailbox driver related changes
 - keystone: support for the "Navigator" component
 - versatile: new reboot, led and soc drivers

212fe84a6f ARM: SoC cleanups for 3.18
This time around, the cleanup branch contains mostly code removal. A number
 of board files for at91, imx and msm have become obsolete because of the
 DT conversion and are now ready to be removed. The OMAP platform has
 traditionally had its own DMA engine abstraction and as this is being
 phased out, a lot of the original code is now unused and can be removed
 as well.
 
 S3C24xx can be simplified now that the restart code is a proper device
 driver.
 
 Finally, a number of cleanups in shmobile are done to prepare for
 the addition of new code in other branches.

 In particular, Robert Jarzmik and Daniel Mack now volunteered to help
 out maintaining the PXA platform, Krzysztof Halasa took over the
 cns3xxx platform, Carlo Caione is the maintainer for the new Amlogic
 meson platform, and Matthias Brugger is now listed for the mediatek
 platform he recently contributed.

fb5ac0de10 cxgb4: clean up a type issue
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.

44783d8751 Merge branch 'fs_enet_napi'
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.

935e2218d5 r8169:add support for RTL8168EP
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.
so I did not add firmware code for it.
