This commit fixes the following sparse warning:

drivers/net/phy/fixed.c:207
    - warning: symbol 'fixed_phy_del' was not declared.
      Should it be static?

by adding symbol definition to the phy_fixed.h API file. It is ok to do
because the function in question is an exported symbol.

Netfilter/nf_tables fixes for net-next

This patchset contains fixes for recent updates available in your
net-next, they are:

1) Fix double memory allocation for accounting objects that results
   in a leak, this slipped through with the new quota extension,
   patch from Mathieu Poirier.

2) Fix broken ordering when adding set element transactions.

3) Make sure that objects are released in reverse order in the abort
   path, to avoid possible use-after-free when accessing dependencies.

4) Allow to delete several objects (as long as dependencies are
   fulfilled) by using one batch. This includes changes in the use
   counter semantics of the nf_tables objects.

5) Fix illegal sleeping allocation from rcu callback.

On the DM9000B, dm9000_msleep() is called during the dm9000_timeout()
routine.  Since dm9000_timeout() holds the main spinlock through the
entire routine, mdelay() needs to be used rather than msleep().
Furthermore, the mutex_lock()/mutex_unlock() should be avoided so as to
not sleep with spinlocks held.

17ad78de7f dm9000: clean up edge-triggered irq compatibility
DM9000 uses level-triggered interrupts.  Some systems (PXA270) only
support edge-triggered interrupts on GPIOs.  Some changes are necessary
to ensure that interrupts are not triggered while the GPIO interrupt is
masked or we will miss the interrupt forever.

* Make some helper functions called dm9000_mask_interrupts() and
  dm9000_unmask_interrupts() for readability.

* dm9000_init_dm9000(): ensure that this function always leaves interrupts
  masked regardless of the state when it entered the function.  This is
  primarily to support the situation in dm9000_open where the logic used
  to go:

    dm9000_open()
        dm9000_init_dm9000()
            unmask interrupts
        request_irq()

  If an interrupt occurred between unmasking the interrupt and
  requesting the irq, it would be missed forever as the edge event would
  never be seen by the GPIO hardware in the PXA270.  This allows us to
  change the logic to:

    dm9000_open()
        dm9000_init_dm9000()
            dm9000_mask_interrupts()
        request_irq()
        dm9000_unmask_interrupts()

* dm9000_timeout(), dm9000_drv_resume(): Add the missing
  dm9000_unmask_interrupts() now required by the change above.

* dm9000_shutdown(): Use mask helper function

* dm9000_interrupt(): Use mask/unmask helper functions

* Change a hard-coded 0x3 to NCR_RST | NCR_MAC_LBK in dm9000_reset

* Every single place where dm9000_init_dm9000 was ran, a dm9000_reset
  was called immediately before-hand.  Bring dm9000_reset into
  dm9000_init_dm9000.

* The following commit updated the dm9000_probe reset routine to use NCR_RST
  | NCR_MAC_LBK:

  and a later commit added a bug-fix to always reset the chip twice:

    09ee9f8 dm9000: Implement full reset of DM9000 network device

  Unfortunately, since the changes in 6741f40 were made by replacing the
  dm9000_probe dm9000_reset with the adjusted iow(), the changes in
  09ee9f8 were not incorporated into the dm9000_probe reset.
  Furthermore, it bypassed the requisite reset-delay causing some boards
  to get at least one "read wrong id ..." dev_err message during
  dm9000_probe.

59ae9fc670 xen-netback: Fix handling of skbs requiring too many slots
A recent commit (a02eb4 "xen-netback: worse-case estimate in xenvif_rx_action is
underestimating") capped the slot estimation to MAX_SKB_FRAGS, but that triggers
the next BUG_ON a few lines down, as the packet consumes more slots than
estimated.
This patch introduces full_coalesce on the skb callback buffer, which is used in
start_new_rx_buffer() to decide whether netback needs coalescing more
aggresively. By doing that, no packet should need more than
(XEN_NETIF_MAX_TX_SIZE + 1) / PAGE_SIZE data slots (excluding the optional GSO
slot, it doesn't carry data, therefore irrelevant in this case), as the provided
buffers are fully utilized.

3b392ddba2 MPLS: Use mpls_features to activate software MPLS GSO segmentation
If an MPLS packet requires segmentation then use mpls_features
to determine if the software implementation should be used.

As no driver advertises MPLS GSO segmentation this will always be
the case.

I had not noticed that this was necessary before as software MPLS GSO
segmentation was already being used in my test environment. I believe that
the reason for that is the skbs in question always had fragments and the
driver I used does not advertise NETIF_F_FRAGLIST (which seems to be the
case for most drivers). Thus software segmentation was activated by
skb_gso_ok().

This introduces the overhead of an extra call to skb_network_protocol()
in the case where where CONFIG_NET_MPLS_GSO is set and
skb->ip_summed == CHECKSUM_NONE.

Thanks to Jesse Gross for prompting me to investigate this.

d4c642ea12 gianfar: Call netif_carrier_off() prior to registration
Quoting David Miller:
"At the moment you call register_netdev() the device is visible, notifications
are sent to userspace, and userland tools can try to bring the interface up
and see the incorrect link state, before you do the netif_carrier_off().

Said another way, between the register_netdev() and netif_carrier_off() call,
userspace can see the device in an inconsistent state."

So call netif_carrier_off() prior to register_netdev().

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2014-06-05

This series contains updates to i40e and i40evf.

Jesse fixes an issue reported by Dave Jones where a couple of FD checks
ended up using bitwise OR where it should have been bitwise AND.

Neerav removes unused defines and macros for receive LRO.  Fix the driver
from allowing the user to set a larger MTU size that the hardware was
being configured to support.  Refactors send version which moves code in
two places into a small helper function.

Kamil modifies register diagnostics since register ranges can vary among
the different NVMs to avoid false test results.  So now we try to identify
the full range and use it for a register test and if we fail to define the
proper register range, we will only test the first register from that
group.  Then removes the check for large buffer since this was added in the
case this structure changed in the future, since the AQ definition is now
mature enough that this check is no longer necessary.

Mitch fixes i40evf driver to allocate descriptors in groups of 32 since the
hardware requires it.  Also fixes a crash when the ring size changed because
it would change the count before deallocating resources, causing the driver
to either free nonexistent buffers or leak leftover buffers.  Fixed the
driver to notify the VF for all types of resets so the VF can attempt a
graceful reinit.

Shannon refactors stats collection to create a unifying stats update routine
to call the various stat collection routines.  Removes rx_errors and
rx_missed stats since they were removed from the chip design.  Added
missing VSI statistics that the hardware offers but are not apart of the
standard netdev stats.

v2: dropped patch "i40e: Allow disabling of DCB via debugfs" from Neerav
    based on feedback from David Miller.

d732a18445 i40evf: fix crash when changing ring sizes
i40evf_set_ringparam was broken in several ways. First, it only changed
the size of the first ring, and second, changing the ring size would
often result in a panic because it would change the count before
deallocating resources, causing the driver to either free nonexistent
buffers, or leak leftover buffers.

Fix this by storing the descriptor count in the adapter structure, and
updating the count for each ring each time we allocate them. This
ensures that we always free the right size ring, and always end up with
the requested count when the device is (re)opened.

c5cc0cfd27 i40e: remove check for large buffer
We introduced this check in case this structure changed in the future,
the AQ definition is now mature enough that this check is no longer necessary.

22dd9ae8af i40e: Rework register diagnostic
Register range, being subject to register diagnostic, can vary among
different NVMs. We will try to identify the full range and use it for
a register test. This is needed to avoid false test results. If we fail
to define the proper register range we will test only the first register
from that group.

d3a90b70d8 i40e: don't use OR to check a value
A couple of FD checks ended up using bitwise OR to check
a value, which ends up always being evaluated to true.

This should fix the issue.  Thanks to DaveJ for noticing
and reporting the issue!

d1cadce15a isdn/capi: fix (middleware) device nodes
Since v2.4 the capi driver used the following device nodes if
"middleware" support was enabled:
    /dev/capi20
    /dev/capi/0
    /dev/capi/1
    [...]

/dev/capi20 is a character device node. /dev/capi/0 (and up) are tty
device nodes (with a different major).

This device node (naming) scheme is not documented anywhere, as far as I
know. It was originally provided by the capifs pseudo filesystem (before
udev became available). It is required for example by the pppd
capiplugin. It was supported until a few years ago. But a number of
developments broke it:
- v2.6.6 (May 2004) renamed /dev/capi20 to /dev/capi and removed the
  "/" from the name of capi's tty driver. The explanation of the patch
  that did this included two examples of udev rules "to restore the old
  namespace";
- either udev 154 (May 2010) or udev 179 (January 2012) stopped
  allowing to rename device nodes, and thus the ability to have
  /dev/capi20 appear instead of /dev/capi and /dev/capi/0 (and up)
  instead of /dev/capi0 (and up);
- v3.0 (July 2011) also removed capifs. That disabled another method to
  create the /dev/capi/0 (and up) device nodes.

So now users need to manually tweak their setup (eg, create /dev/capi/
and fill that with symlinks) to get things working. This is all rather
hacky and only discoverable by searching the web. Fix all this by
renaming /dev/capi back to /dev/capi20, and by setting the name of the
"capi_nc" tty driver to "capi!" so the tty device nodes appear as
/dev/capi/0 (and up).

a79f5d2612 isdn/capi: Make verbose reporting depend on capidrv
The Kconfig symbol ISDN_DRV_AVMB1_VERBOSE_REASON is only used for
capi_info2str(). That function is only used in capidrv.c. So setting it
without setting ISDN_CAPI_CAPIDRV is pointless. Make it depend on
ISDN_CAPI_CAPIDRV, rename it to ISDN_CAPI_CAPIDRV_VERBOSE and put its
entry after ISDN_CAPI_CAPIDRV's entry.

Since this symbol seems to be primarily used for debugging, keep it off
by default. By now the last users of capidrv hopefully know all they
need to know about the reasons for disconnecting.

ca05e3a755 isdn/capi: move capi_info2str to capidrv.c
capi_info2str() is apparently meant to be of general utility. It is
actually only used in capidrv.c. So move it from capiutil.c to
capidrv.c and (obviously) stop exporting it.

And, since we're touching this, merge the two versions of this
function.
