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"

a4e90bed51 ACPI / sleep: Add extra checks for HW Reduced ACPI mode sleep states
If the HW Reduced ACPI mode bit is set in the FADT, ACPICA uses
the optional sleep control and sleep status registers for making
the system enter sleep states (including S5), so it is not possible
to use system sleep states or power it off using ACPI if the HW
Reduced ACPI mode bit is set and those registers are not available.

For this reason, add a new function, acpi_sleep_state_supported(),
checking if the HW Reduced ACPI mode bit is set and whether or not
system sleep states are usable in that case in addition to checking
the return value of acpi_get_sleep_type_data() and make the ACPI
sleep setup routines use that function to check the availability of
system sleep states.

Among other things, this prevents the kernel from attempting to
use ACPI for powering off HW Reduced ACPI systems without the sleep
control and sleep status registers, because ACPI power off doesn't
have a chance to work on them.  That allows alternative power off
mechanisms that may actually work to be used on those systems.  The
affected machines include Dell Venue 8 Pro, Asus T100TA, Haswell
Desktop SDP and Ivy Bridge EP Demo depot.

ecab67015e ipv6: Avoid unnecessary temporary addresses being generated
tmp_prefered_lft is an offset to ifp->tstamp, not now. Therefore
age needs to be added to the condition.

Age calculation in ipv6_create_tempaddr is different from the one
in addrconf_verify and doesn't consider ADDRCONF_TIMER_FUZZ_MINUS.
This can cause age in ipv6_create_tempaddr to be less than the one
in addrconf_verify and therefore unnecessary temporary address to
be generated.
Use age calculation as in addrconf_modify to avoid this.

702eca02b7 sh_eth: update OF PHY registeration
If the sh_eth device is registered using OF, then the driver
should call of_mdiobus_register() to register the PHYs described
in the devicetree and then use of_phy_connect() to connect the
PHYs to the device.

This ensures that any PHYs registered in the device tree are
appropriately connected to the parent devices nodes so that
the PHY drivers can access their OF properties.

84fe61821e eth: fec: Fix lost promiscuous mode after reconnecting cable
If the Freescale fec is in promiscuous mode and network cable is
reconnected then the promiscuous mode get lost. The problem is caused
by a too soon call of set_multicast_list to re-enable promisc mode.
The FEC_R_CNTRL register changes are overwritten by fec_restart.

This patch fixes this by moving the call behind the init of FEC_R_CNTRL
register in fec_restart.

fb00bc2e6c bonding: set correct vlan id for alb xmit path
The commit d3ab3ffd1d
(bonding: use rlb_client_info->vlan_id instead of ->tag)
remove the rlb_client_info->tag, but occur some issues,
The vlan_get_tag() will return 0 for success and -EINVAL for
error, so the client_info->vlan_id always be set to 0 if the
vlan_get_tag return 0 for success, so the client_info would
never get a correct vlan id.

We should only set the vlan id to 0 when the vlan_get_tag return error.

Fixes: d3ab3ffd1d (bonding: use rlb_client_info->vlan_id instead of ->tag)

====================
Don't receive packets when the napi budget == 0

To the best of understanding processing any received packets when the
napi budget == 0 is broken driver behavior.  At the same time I don't
think we have ever cared before so there are a handful of drivers that
need fixes.

I care now as I will shortly be using htis in netpoll to get the
tx queue processing without the rx queue processing.

Drivers that need fixes are few and far between, and so far I have only
found two of them.  More similar patches later if I find more drivers
that need fixes.

their minimal size needed, thus making the code identical and hence

Carolyn provides a fix for igb where using ethtool for EEE settings, which
was not working correctly.

Jacob provides some trivial cleanups and fixes for ixgbe which mainly
dealt with the file headers.

Julia Lawall provides a one fix for ixgbevf where the driver did not need
to adjust the power state on suspend, so the call to pci_set_power_state()
in the resume function was a no-op.

For the mac80211 bits, Johannes says:

"This time, I have a number of small fixes and improvements, and those
are fairly straight-forward. More interesting changes come from Luca
with some preparations for the CSA work, mostly around interface/channel
combinations checking. One other possibly interesting change is a small
one by myself to add NAPI support back to mac80211, which can help
improve TCP behaviour through GRO."

For the Bluetooth bits, Gustavo says:

"This is our first pull request for 3.15, the main feature here is the addition of
the privacy feature for low energy devices. Other than that we have a bunch of small
improvements, fixes, and clean ups all over the tree."

And...

"Another pull request to 3.15. Here we have the second part of the LE private
feature, the LE auto-connect feature and improvements to the power off
procedures. The rest are small improvements, clean up, and fixes."

For the iwlwifi bits, Emmanuel says:

"I have here a whole bunch of various things. Trivial cleanups,
debugfs handlers and new stuff for the new generation of devices
along with new capabilities for monitor mode. We also have support
for power save for dual interface mode, but that is not supported by
the firmware currently available."

And for the Atheros bits, Kalle says:

"For ath10k Alexander did some cleanup to PCI error cases and switched
ath10k to use pci_enable_msi_range(). Michal implemented AP CSA support
and sta_rc_update() operation. I enabled firmware "STA quick kickout"
functionality for faster detection of disappeared clients.

Also there are lots of small fixes to everywhere from various people."

I pulled the wireless tree to avoid some merge conflicts, and I
reverted the staging patch that I had mistakenly merged previously.
Along with that, mwifiex, brcmfmac, wil6210, ath9k, and a few other
drivers get their usual round of updates.  Also notable is the addition
of yet another driver in the rtlwifi family.

 ...

I have amended this commit request to correct the build problems in
staging, including a warning added to one of the staging drivers by
the wireless-next tree.  I also included a fix from Larry Finger to
address an issue found in rtl8723be by Dan Carpenter and smatch.

4e3b3bcd81 rtlwifi: rtl8723be: Fix array dimension problems
Commit a619d1abe2 leads to the following static checker warning:

drivers/net/wireless/rtlwifi/rtl8723be/phy.c:667 _rtl8723be_store_tx_power_by_rate()
error: buffer overflow 'rtlphy->tx_power_by_rate_offset[band]' 4 <= 5

This warning arises because the code is testing the indices for the wrong maximum
values. In addition, the tests merely putput a warning, and then procedes to
corrupt memory. With this change, any such invalid memory access is avoided.

and added "_ieee80211_is_robust_mgmt_frame" as a direct replacement
for the older API.  This is the same fix that was applied to the other
rtlwifi drivers in that commit.

433131ba03 net: sctp: remove NULL check in sctp_assoc_update_retran_path
This is basically just to let Coverity et al shut up. Remove an
unneeded NULL check in sctp_assoc_update_retran_path().

It is safe to remove it, because in sctp_assoc_update_retran_path()
we iterate over the list of transports, our own transport which is
asoc->peer.retran_path included. In the iteration, we skip the
list head element and transports in state SCTP_UNCONFIRMED.

Such transports came from peer addresses received in INIT/INIT-ACK
address parameters. They are not yet confirmed by a heartbeat and
not available for data transfers.

We know however that in the list of transports, even if it contains
such elements, it at least contains our asoc->peer.retran_path as
well, so even if next to that element, we only encounter
SCTP_UNCONFIRMED transports, we are always going to fall back to
asoc->peer.retran_path through sctp_trans_elect_best(), as that is
for sure not SCTP_UNCONFIRMED as per fbdf501c93 ("sctp: Do no
select unconfirmed transports for retransmissions").

Whenever we call sctp_trans_elect_best() it will give us a non-NULL
element back, and therefore when we break out of the loop, we are
guaranteed to have a non-NULL transport pointer, and can remove
the NULL check.

0a8d8c446b vmxnet3: fix building without CONFIG_PCI_MSI
Since commit d25f06ea46 "vmxnet3: fix netpoll race condition",
the vmxnet3 driver fails to build when CONFIG_PCI_MSI is disabled,
because it unconditionally references the vmxnet3_msix_rx()
function.

To fix this, use the same #ifdef in the caller that exists around
the function definition.

4b0c82529b drm/vmwgfx: Fix a surface reference corner-case in legacy emulation mode
If running on a gb-object capable device with a non-gb capable surface
exporter (X server) and a gb capable surface referencing client (GL driver),
the referencing client expects to find a shareable backing buffer attached to
the surface at reference time. This may not be the case if the surface has
not yet been validated. This would cause the surface reference IOCTL to
return an error.
