Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking bugfixes from David Miller:
 "Several bug fixes rolling in, some for changes introduced in this
  merge window, and some for problems that have existed for some time:

  1) Fix prepare_to_wait() handling in AF_VSOCK, from Claudio Imbrenda.

  2) The new DST_CACHE should be a silent config option, from Dave
     Jones.

  3) inet_current_timestamp() unintentionally truncates timestamps to
     16-bit, from Deepa Dinamani.

  4) Missing reference to netns in ppp, from Guillaume Nault.

  5) Free memory reference in hv_netvsc driver, from Haiyang Zhang.

  6) Missing kernel doc documentation for function arguments in various
     spots around the networking, from Luis de Bethencourt.

  7) UDP stopped receiving broadcast packets properly, due to
     overzealous multicast checks, fix from Paolo Abeni"
