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"

Cong Wang 03c0535554 NFC: Close a race condition in llcp_sock_getname()
llcp_sock_getname() checks llcp_sock->dev to make sure
llcp_sock is already connected or bound, however, we could
be in the middle of llcp_sock_bind() where llcp_sock->dev
is bound and llcp_sock->service_name_len is set,
but llcp_sock->service_name is not, in this case we would
lead to copy some bytes from a NULL pointer.

Just lock the sock since this is not a hot path anyway.

David S. Miller 15ab90f400 Merge tag 'nfc-next-4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next
Samuel Ortiz says:

====================
NFC 4.5 pull request

This is the first NFC pull request for 4.5 and it brings:

- A new driver for the STMicroelectronics ST95HF NFC chipset.
  The ST95HF is an NFC digital transceiver with an embedded analog
  front-end and as such relies on the Linux NFC digital
  implementation. This is the 3rd user of the NFC digital stack.

- ACPI support for the ST st-nci and st21nfca drivers.

- A small improvement for the nfcsim driver, as we can now tune
  the Rx delay through sysfs.

- A bunch of minor cleanups and small fixes from Christophe Ricard,
  for a few drivers and the NFC core code.

Eric Dumazet 9cd3e072b0 net: rename SOCK_ASYNC_NOSPACE and SOCK_ASYNC_WAITDATA
This patch is a cleanup to make following patch easier to
review.

Goal is to move SOCK_ASYNC_NOSPACE and SOCK_ASYNC_WAITDATA
from (struct socket)->flags to a (struct socket_wq)->flags
to benefit from RCU protection in sock_wake_async()

To ease backports, we rename both constants.

Two new helpers, sk_set_bit(int nr, struct sock *sk)
and sk_clear_bit(int net, struct sock *sk) are added so that
following patch can change their implementation.

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.
