Pull networking fixes from David Miller:
 "I know this is a bit more than you want to see, and I've told the
  wireless folks under no uncertain terms that they must severely scale
  back the extent of the fixes they are submitting this late in the
  game.

  Anyways:

   1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which
      is the correct implementation, like it should.  Instead it does
      something like a NAPI poll operation.  This leads to crashes.

      From Neil Horman and Arnd Bergmann.

   2) Segmentation of SKBs requires proper socket orphaning of the
      fragments, otherwise we might access stale state released by the
      release callbacks.

      This is a 5 patch fix, but the initial patches are giving
      variables and such significantly clearer names such that the
      actual fix itself at the end looks trivial.

      From Michael S.  Tsirkin.

   3) TCP control block release can deadlock if invoked from a timer on
      an already "owned" socket.  Fix from Eric Dumazet.

   4) In the bridge multicast code, we must validate that the
      destination address of general queries is the link local all-nodes
      multicast address.  From Linus Lüssing.

   5) The x86 BPF JIT support for negative offsets puts the parameter
      for the helper function call in the wrong register.  Fix from
      Alexei Starovoitov.

   6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the
      r8169 driver is incorrect.  Fix from Hayes Wang.

   7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see
      if a packet is a GSO frame, but that's not the correct test.  It
      should use skb_is_gso(skb) instead.  Fix from Wei Liu.

   8) Negative msg->msg_namelen values should generate an error, from
      Matthew Leach.

   9) at86rf230 can deadlock because it takes the same lock from it's
      ISR and it's hard_start_xmit method, without disabling interrupts
      in the latter.  Fix from Alexander Aring.

  10) The FEC driver's restart doesn't perform operations in the correct
      order, so promiscuous settings can get lost.  Fix from Stefan
      Wahren.

  11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann.

  12) Reference count and memory leak fixes in TIPC from Ying Xue and
      Erik Hugne.

  13) Forced eviction in inet_frag_evictor() must strictly make sure all
      frags are deleted, otherwise module unload (f.e.  6lowpan) can
      crash.  Fix from Florian Westphal.

  14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
      uses as a hash function), which breaks on PowerPC.  From Anton
      Blanchard.

      The main gist of the issue is that csum_partial() is defined only
      as a value that, once folded (f.e.  via csum_fold()) produces a
      correct 16-bit checksum.  It is legitimate, therefore, for
      csum_partial() to produce two different 32-bit values over the
      same data if their respective alignments are different.

  15) Fix endiannes bug in MAC address handling of ibmveth driver, also
      from Anton Blanchard.

  16) Error checks for ipv6 exthdrs offload registration are reversed,
      from Anton Nayshtut.

  17) Externally triggered ipv6 addrconf routes should count against the
      garbage collection threshold.  Fix from Sabrina Dubroca.

  18) The PCI shutdown handler added to the bnx2 driver can wedge the
      chip if it was not brought up earlier already, which in particular
      causes the firmware to shut down the PHY.  Fix from Michael Chan.

  19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
      currently coded it can and does trigger in legitimate situations.
      From Eric Dumazet.

  20) BNA driver fails to build on ARM because of a too large udelay()
      call, fix from Ben Hutchings.

  21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix
      from Eric Dumazet.

  22) The vlan passthrough ops added in the previous release causes a
      regression in source MAC address setting of outgoing headers in
      some circumstances.  Fix from Peter Boström"

Instructs the socket layer which kind of information should be collected
and/or reported. The parameter is an integer with some of the following
bits set. Setting other bits is an error and doesn't change the current
state.
SOF_TIMESTAMPING_TX_HARDWARE: try to obtain send time stamp in hardware
SOF_TIMESTAMPING_TX_SOFTWARE: if SOF_TIMESTAMPING_TX_HARDWARE is off or
fails, then do it in software
SOF_TIMESTAMPING_RX_HARDWARE: return the original, unmodified time stamp
as generated by the hardware
SOF_TIMESTAMPING_RX_SOFTWARE: if SOF_TIMESTAMPING_RX_HARDWARE is off or
fails, then do it in software
SOF_TIMESTAMPING_RAW_HARDWARE: return original raw hardware time stamp
SOF_TIMESTAMPING_SYS_HARDWARE: return hardware time stamp transformed to
the system time base
SOF_TIMESTAMPING_SOFTWARE: return system time stamp generated in
software
Four of the bits are requests to the stack to try to generate
timestamps. Any combination of them is valid.
SOF_TIMESTAMPING_TX/RX determine how time stamps are generated.
SOF_TIMESTAMPING_RAW/SYS determine how they are reported in the
following control message:
SOF_TIMESTAMPING_TX_HARDWARE: try to obtain send time stamps in hardware
SOF_TIMESTAMPING_TX_SOFTWARE: try to obtain send time stamps in software
SOF_TIMESTAMPING_RX_HARDWARE: try to obtain receive time stamps in hardware
SOF_TIMESTAMPING_RX_SOFTWARE: try to obtain receive time stamps in software
The other three bits control which timestamps will be reported in a
generated control message. If none of these bits are set or if none of
the set bits correspond to data that is available, then the control
message will not be generated:
SOF_TIMESTAMPING_SOFTWARE: report systime if available
SOF_TIMESTAMPING_SYS_HARDWARE: report hwtimetrans if available
SOF_TIMESTAMPING_RAW_HARDWARE: report hwtimeraw if available
It is worth noting that timestamps may be collected for reasons other
than being requested by a particular socket with
SOF_TIMESTAMPING_[TR]X_(HARD|SOFT)WARE. For example, most drivers that
can generate hardware receive timestamps ignore
SOF_TIMESTAMPING_RX_HARDWARE. It is still a good idea to set that flag
in case future drivers pay attention.
If timestamps are reported, they will appear in a control message with
cmsg_level==SOL_SOCKET, cmsg_type==SO_TIMESTAMPING, and a payload like
this:
struct scm_timestamping {
struct timespec systime;
