Pull networking updates from David Miller:

 1) More iov_iter conversion work from Al Viro.

    [ The "crypto: switch af_alg_make_sg() to iov_iter" commit was
      wrong, and this pull actually adds an extra commit on top of the
      branch I'm pulling to fix that up, so that the pre-merge state is
      ok.   - Linus ]

 2) Various optimizations to the ipv4 forwarding information base trie
    lookup implementation.  From Alexander Duyck.

 3) Remove sock_iocb altogether, from CHristoph Hellwig.

 4) Allow congestion control algorithm selection via routing metrics.
    From Daniel Borkmann.

10) Add support for uniqu flow IDs to openvswitch, from Joe Stringer.

11) New NetCP ethernet driver, from Muralidharan Karicheri and Wingman
    Kwok.

12) More sanely handle out-of-window dupacks, which can result in
    serious ACK storms.  From Neal Cardwell.

13) Various rhashtable bug fixes and enhancements, from Herbert Xu,
    Patrick McHardy, and Thomas Graf.

14) Support xmit_more in be2net, from Sathya Perla.

When IOMMU bypass is enabled, a PCI device can read and write memory
that was not mapped by the driver without causing an EEH. That might
cause memory corruption, for example.

When we disable bypass, DMA reads and writes to addresses not mapped by
the IOMMU will cause an EEH, allowing us to debug such issues.

Pull input subsystem fixes from Dmitry Torokhov.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: uinput - fix ioctl nr overflow for UI_GET_SYSNAME/VERSION
  Input: I8042 - add Acer Aspire 7738 to the nomux list
  Input: elantech - support new ICs types for version 4
  Input: i8042 - reset keyboard to fix Elantech touchpad detection
  MAINTAINERS: remove Dmitry Torokhov's alternate address

Here's a big pile of changes for this round.

We have
 * a lot of regulatory code changes to deal with the
   way newer Intel devices handle this
 * a change to drop packets while disconnecting from
   an AP instead of trying to wait for them
 * a new attempt at improving the tailroom accounting
   to not kick in too much for performance reasons
 * improvements in wireless link statistics
 * many other small improvements and small fixes that
   didn't seem necessary for 3.19 (e.g. in hwsim which
   is testing only code)
