Pull networking updates from David Miller:
 "Highlights:

   1) Support more Realtek wireless chips, from Jes Sorenson.

   2) New BPF types for per-cpu hash and arrap maps, from Alexei
      Starovoitov.

   3) Make several TCP sysctls per-namespace, from Nikolay Borisov.

   4) Allow the use of SO_REUSEPORT in order to do per-thread processing
   of incoming TCP/UDP connections.  The muxing can be done using a
   BPF program which hashes the incoming packet.  From Craig Gallek.

   5) Add a multiplexer for TCP streams, to provide a messaged based
      interface.  BPF programs can be used to determine the message
      boundaries.  From Tom Herbert.

   6) Add 802.1AE MACSEC support, from Sabrina Dubroca.

   7) Avoid factorial complexity when taking down an inetdev interface
      with lots of configured addresses.  We were doing things like
      traversing the entire address less for each address removed, and
      flushing the entire netfilter conntrack table for every address as
      well.

   8) Add and use SKB bulk free infrastructure, from Jesper Brouer.

   9) Allow offloading u32 classifiers to hardware, and implement for
      ixgbe, from John Fastabend.

  10) Allow configuring IRQ coalescing parameters on a per-queue basis,
      from Kan Liang.

  11) Extend ethtool so that larger link mode masks can be supported.
      From David Decotigny.

  12) Introduce devlink, which can be used to configure port link types
      (ethernet vs Infiniband, etc.), port splitting, and switch device
      level attributes as a whole.  From Jiri Pirko.

  13) Hardware offload support for flower classifiers, from Amir Vadai.

  14) Add "Local Checksum Offload".  Basically, for a tunneled packet
      the checksum of the outer header is 'constant' (because with the
      checksum field filled into the inner protocol header, the payload
      of the outer frame checksums to 'zero'), and we can take advantage
      of that in various ways.  From Edward Cree"

Jean Delvare 87aca73737 NFC: microread: Drop platform data header file
Originally I only wanted to drop the unneeded inclusion of
<linux/i2c.h>, but then noticed that struct
microread_nfc_platform_data isn't actually used, and
MICROREAD_DRIVER_NAME is redefined in the only file where it is used,
so we can get rid of the header file and dead code altogether.

Mika Westerberg dd215430dc NFC: pn544: Drop two useless checks in ACPI probe path
When pn544_hci_i2c_acpi_request_resources() gets called we
already know that the entries in ->acpi_match_table have
matched ACPI ID of the device.
In addition I2C client pointer cannot be NULL in any case
(otherwise I2C core would not call ->probe() for the driver
in the first place).

Drop the two useless checks from the driver.

Fabio Estevam 59df9bb25c nxp-nci: i2c: Do not check specifically for -EREMOTEIO error
Function nxp_nci_i2c_write currently assumes in case of
I2C bus NACK that the NFC device is in stand-by mode and
will retry the I2C transaction after a pause. This assumes
that the first failed I2C transaction will wake-up the device.

This is done by checking on EREMOTEIO, which is wrong. According
to Documentation/i2c/fault-codes ENXIO shall be used. Unfortunately
the NOACK return code is currently inconsistent across various I2C
host controller drivers. So only check for the generic error case
instead.

This is a temporary fix. As soon as all I2C bus master drivers are
fixed to consistently return 'ENXIO', then we can do the specific
error check again.

Linus Torvalds 75f5db39ff spi: Updates for v4.4
Quite a lot of activity in SPI this cycle, almost all of it in drivers
 with a few minor improvements and tweaks in the core.
 
  - Updates to pxa2xx to support Intel Broxton and multiple chip selects.
  - Support for big endian in the bcm63xx driver.
  - Multiple slave support for the mt8173
  - New driver for the auxiliary SPI controller in bcm2835 SoCs.
  - Support for Layerscale SoCs in the Freescale DSPI driver.

Linus Torvalds 8e483ed134 char/misc drivers for 4.4-rc1
Here is the big char/misc driver update for 4.4-rc1.  Lots of different
 driver and subsystem updates, hwtracing being the largest with the
 addition of some new platforms that are now supported.  Full details in
 the shortlog.
 
 All of these have been in linux-next for a long time with no reported issues.

Vincent Cuissard b2fe288eac NFC: nfcmrvl: free reset gpio
Reset GPIO shall be freed by the driver since the device used
in devm_ calls can be still valid on unregister.

If user removes the module and inserts it again, the devm_gpio_request
will fail because the underlying physical device (e.g i2c) was not
removed so the device management won't have freed the gpio.

Arnd Bergmann 1dbac5c578 NFC: nfcmrvl: fix SPI driver dependencies
The newly added nfcmrvl_spi driver uses the spi_nci
infrastructure, but does not have a Kconfig dependency on
that, so we can get a link-time error:

drivers/built-in.o: In function `nfcmrvl_spi_nci_send':
(.text+0x1428dc): undefined reference to `nci_spi_send'
drivers/built-in.o: In function `nfcmrvl_spi_probe':

drivers/built-in.o: In function `nfcmrvl_spi_int_irq_thread_fn':

Christophe Ricard 15d17170b4 NFC: st21nfca: Add support for proprietary commands
Add support for proprietary commands useful mainly
for factory testings.

Here is a list:

- FACTORY_MODE: Allow to set the driver into a mode where no
  secure element are activated. It does not consider any
  NFC_ATTR_VENDOR_DATA.
- HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes
  command. It does not consider any NFC_ATTR_VENDOR_DATA.
- HCI_DM_PUT_DATA: Allow to configure specific CLF registry as
  for example RF trimmings or low level drivers configurations
  (I2C, SPI, SWP).
- HCI_DM_UPDATE_AID: Allow to configure an AID routing into the
  CLF routing table following RF technology, CLF mode or protocol.
- HCI_DM_GET_INFO: Allow to retrieve CLF information.
- HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as
  low level drivers configurations or RF trimmings.
- HCI_DM_LOAD: Allow to load a firmware into the CLF. A complete
  packet can be more than 8KB.
- HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF
  configuration changes without CLF power off.
- HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example
  the white list).
- HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF
  technology. When using this command to anti-collision is done.
- HCI_LOOPBACK: Allow to echo a command and test the Dh to CLF
  connectivity.
