Some versions of MCFW do not support the MC_CMD_VADAPTOR_SET_MAC
command, and ENOSYS will be returned.

If the PF created its own vport, the function's datapath must be
stopped and the vport can be reconfigured to reflect the new MAC
address.

If the MCFW created the vport for the PF (which is the case when
the nic_data->vport_mac is blank), nothing further needs to be
done as the vport is not under the control of the PF.

This only applies to PFs because the MCFW in question does not
support VFs.

Re-organize the structure of error handling to avoid having
to duplicate the netif_err() around the ifdefs.

The only change to the behaviour of the error-handling is that
the PF's data structure to record VF details should only be
updated if the original command succeeded.

is set to "failure" then whenever primary interface's link get back(up)
it become active slave even if current active slave is still up.

With this patch, "bond_find_best_slave" will not traverse members if

Frag needed should be sent only if the inner header asked

Jason Gunthorpe reported that since commit c02db8c6 ("rtnetlink: make
SR-IOV VF interface symmetric"), we don't verify IFLA_VF_INFO attributes
anymore with respect to their policy, that is, ifla_vfinfo_policy[].

Before, they were part of ifla_policy[], but they have been nested since
placed under IFLA_VFINFO_LIST, that contains the attribute IFLA_VF_INFO,
which is another nested attribute for the actual VF attributes such as
IFLA_VF_MAC, IFLA_VF_VLAN, etc.

Despite the policy being split out from ifla_policy[] in this commit,
it's never applied anywhere. nla_for_each_nested() only does basic nla_ok()
testing for struct nlattr, but it doesn't know about the data context and
their requirements.

Fix, on top of Jason's initial work, does 1) parsing of the attributes
with the right policy, and 2) using the resulting parsed attribute table
from 1) instead of the nla_for_each_nested() loop (just like we used to
do when still part of ifla_policy[]).

When a switch is attached to the mdio bus, the mdio bus can be used
while the interface is not open. If the IPG clock is not enabled, MDIO
reads/writes will simply time out.

Add support for runtime PM to control this clock. Enable/disable this
clock using runtime PM, with open()/close() and mdio read()/write()
function triggering runtime PM operations. Since PM is optional, the
IPG clock is enabled at probe and is no longer modified by
fec_enet_clk_enable(), thus if PM is not enabled in the kernel, it is
guaranteed the clock is running when MDIO operations are performed.

If rhashtable_walk_next detects a resize operation in progress, it jumps
to the new table and continues walking that one. But it misses to drop
the reference to it's current item, leading it to continue traversing
the new table's bucket in which the current item is sorted into, and
after reaching that bucket's end continues traversing the new table's
second bucket instead of the first one, thereby potentially missing
items.

This fixes the rhashtable runtime test for me. Bug probably introduced

A couple of regressions crept in because of a patch to use proper list
APIs rather than manually reading & writing the next/prev pointers
(commit 835a6a2f). Turns out this was
masking a few bugs: a missing INIT_LIST_HEAD() call and incorrectly
using list_del() rather than list_del_init(). The two patches in this
set fix these, and it'd be nice they could still make it to 4.2-rc1 to

In enic_poll, we clean tx and rx queues, when low latency busy socket polling
is happening, enic_poll will only clean tx queue. After cleaning tx, it should
return total budget for re-poll.

There is a small window between vnic_intr_unmask() and enic_poll_unlock_napi().
In this window if an irq occurs and napi is scheduled on different cpu, it tries
to acquire enic_poll_lock_napi() and fails. Unlock napi_poll before unmasking
the interrupt.

Pull init.h/module.h fragility fixes from Paul Gortmaker:
 "Fixup various init.h misuses that are fragile wrt code moving to

  What started as a removal of no longer required include <linux/init.h>
  due to the earlier __cpuinit and __devinit removal led to the
  observation that some module specfic support was living in init.h
  itself, thus preventing the full removal from introducing compile
  regressions.

  This series includes a few final fixups needed prior to the relocation
  of the modular init code from <init.h> to <module.h>.  These are
  things that weren't easily categorized into any of the other previous
  series categories already requested for pull.

  That said, each fixup branch (including this one) is independent and
  there are no ordering constraints.  Only the final code relocation
  (which is NOT in this pull) requires that all my cleanup branches be

Pull module_platform_driver replacement from Paul Gortmaker:
 "Replace module_platform_driver with builtin_platform driver in non
  modules.

  We see an increasing number of non-modular drivers using
  modular_driver() type register functions.  There are several downsides
  to letting this continue unchecked:

   - The code can appear modular to a reader of the code, and they won't
     know if the code really is modular without checking the Makefile
     and Kconfig to see if compilation is governed by a bool or
     tristate.

   - Coders of drivers may be tempted to code up an __exit function that
     is never used, just in order to satisfy the required three args of
     the modular registration function.

   - Non-modular code ends up including the <module.h> which increases
     CPP overhead that they don't need.

   - It hinders us from performing better separation of the module init
     code and the generic init code.

  So here we introduce similar macros for builtin drivers.  Then we
  convert builtin drivers (controlled by a bool Kconfig) by making the
  following type of mapping:

    module_platform_driver()       --->  builtin_platform_driver()
    module_platform_driver_probe() --->  builtin_platform_driver_probe().

  The set of drivers that are converted here are just the ones that
  showed up as relying on an implicit include of <module.h> during a
  pending header cleanup.  So we convert them here vs adding an include
  of <module.h> to non-modular code to avoid compile fails.  Additonal
  conversions can be done asynchronously at any time.

  Once again, an unused module_exit function that is removed here
  appears in the diffstat as an outlier wrt all the other changes"

Pull module_init replacement part two from Paul Gortmaker:
 "Replace module_init with appropriate alternate initcall in non
  modules.

  This series converts non-modular code that is using the module_init()
  call to hook itself into the system to instead use one of our
  alternate priority initcalls.

  Unlike the previous series that used device_initcall and hence was a
  runtime no-op, these commits change to one of the alternate initcalls,
  because (a) we have them and (b) it seems like the right thing to do.

  For example, it would seem logical to use arch_initcall for arch
  specific setup code and fs_initcall for filesystem setup code.

  This does mean however, that changes in the init ordering will be
  taking place, and so there is a small risk that some kind of implicit
  init ordering issue may lie uncovered.  But I think it is still better
  to give these ones sensible priorities than to just assign them all to
  device_initcall in order to exactly preserve the old ordering.

  Thad said, we have already made similar changes in core kernel code in
  commit c96d6660 ("kernel: audit/fix non-modular users of
  module_init in core code") without any regressions reported, so this
  type of change isn't without precedent.  It has also got the same

   and rather do the preparatory steps for 4.3, so we can run the final

Pul IOMMU fixes from Joerg Roedel:
 "Four fixes have queued up to fix regressions introduced after v4.1:

   - Don't fail IOMMU driver initialization when the add_device
     call-back returns -ENODEV, as that just means that the device is
     not translated by the IOMMU.  This is pretty common on ARM.

   - Two fixes for the ARM-SMMU driver for a wrong feature check and to
     remove a redundant NULL check.

   - A fix for the AMD IOMMU driver to fix a boot panic on systems where
     the BIOS requests Unity Mappings in the IVRS table"
