The debugging helpers for showing descriptor rings were
dumping the indexes in decimal and the offsets in hex.
Put everything in hex and at least be consistent.

This is the "Don't Give Up" patch. Previously the
driver could fail an allocation, and then possibly stall
a queue forever, by never coming back to continue receiving
or allocating buffers.
With this patch, the driver will keep polling trying to allocate
receive buffers until it succeeds. This should keep all receive
queues running even in the face of memory pressure.

While re-enabling interrupts the driver would clear all pending
causes. This meant that if an interrupt was generated while the driver
was cleaning or polling with interrupts disabled, then that interrupt
was lost. This could cause a queue to become dead, especially for
receive. Refactored the enable_icr0 function in order to allow
it to be decided by the caller whether the CLEARPBA (clear pending
events) bit will be set while re-enabling the interrupt.

Now that the Force-WriteBack functionality in X710/XL710 devices
has been moved out of the clean routine and into the service task,
we need to make sure WriteBack-On-ITR is separated out since it
is still called from clean.
In the X722 devices, Force-WriteBack implies WriteBack-On-ITR but
without the interrupt, which put the driver into a missed
interrupt scenario and a potential tx-timeout report.
With this patch, we break the two functions out, and call the
appropriate ones at the right place. This will avoid creating missed
interrupt like scenarios for X722 devices.

With the latest firmware, statistics gathering can now be enabled and
disabled in the HW switch, so we need to add a parameter to allow the
driver to set it as desired. At the same time, the L2 cloud filtering
parameter has been removed as it was never used.
Older drivers working with the newer firmware and newer drivers working
with older firmware will not run into problems with these bits as the
defaults are reasonable and there is no overlap in the bit definitions.
Also, newer drivers will be forced to update because of the change in
function call parameters, a reminder that the functionality exists.

The sync_vsi_filters function is moved up in the service_task because
it may need to request a reset, and we don't want to wait another round

For the Marvell 88E1510, marvell_of_reg_init was called too late, in the
config_aneg function.
Since commit 113c74d83eef ("net: phy: turn carrier off on phy attach"),
this lead to the link not coming up at boot anymore, due to the phy
state machine being stuck at waiting for interrupts (off by default on
the 88E1510).
For seven other Marvell PHYs, marvell_of_reg_init was not called at all.
Add a generic marvell_config_init function, which in turn calls
marvell_of_reg_init.
PHYs, which already have a specific config_init function with a call to
marvell_of_reg_init, are left untouched. The generic marvell_config_init
function is called for all the others, to get consistent behavior across
all Marvell PHYs.

Remove the ftrace module notifier in favor of directly calling
ftrace_module_enable() and ftrace_release_mod() in the module loader.
Hard-coding the function calls directly in the module loader removes
dependence on the module notifier call chain and provides better
visibility and control over what gets called when, which is important
to kernel utilities such as livepatch.
This fixes a notifier ordering issue in which the ftrace module notifier
(and hence ftrace_module_enable()) for coming modules was being called
after klp_module_notify(), which caused livepatch modules to initialize
incorrectly. This patch removes dependence on the module notifier call
chain in favor of hard coding the corresponding function calls in the
module loader. This ensures that ftrace and livepatch code get called in
the correct order on patch module load and unload.

when created/modified/deleted. If the notification returned an error,
this error was returned from the tunnel function. If there were no
listeners, the error code ESRCH was returned, even though having no
listeners is not an error. Other calls to this and other similar
notification functions either ignore the error code, or filter ESRCH.
This patch checks for ESRCH and does not flag this as an error.

40GbE Intel Wired LAN Driver Updates 2016-02-17
This series contains updates to i40e/i40evf only.
Jesse cleans up a duplicate declaration in probe. Then fixes a bug where the
driver was using a offset based off a DMA handle while mapping and unmapping
using sync_single_range_for_[cpu|device], when it should be using DMA handle
(returned from alloc_coherent) and the offset of the memory to be sync'd.
Fixed an issue where sync_vsi_filter() was allocating memory in a way that
could sleep (GFP_KERNEL) which was causing a problem when called by the
team driver under rcu_read_lock().
Shannon adds a check to ensure we do not attempt to do TSO when
skb->ip_summed is not set to CHECKSUM_PARTIAL.
Kiran add functions related to port mirroring features such as add/delete
mirror rule.
Jacob assigns the i40e_pf structure directly instead of using a large
memcpy, to avoid a sparse warning and lets the compiler optimize the copy
since it know the size of the structure in advance.
Anjali enables GENEVE capability for XL710/X710 devices with firmware API
version higher than 1.4. Added flag for automatic rule eviction feature

amd-xgbe: AMD XGBE driver updates 2016-02-12
The following updates and fixes are included in this driver update series:
- Disable VLAN filtering in promiscuous mode
- Change from using napi_complete to napi_complete_done
- Use __napi_schedule_irqoff when running in interrupt context
- Verify ethtool speed setting is valid for the selected speedset
- Enable PFC based on the pfc_en setting
- Fix the mapping of priorities to traffic classes
- Do traffic class setup when DCB nl callbacks are invoked
- Check Rx queue fifos before stopping Rx queue DMA
- Switch from disable_irq to masking interrupts for auto-negotiation
This patch series is based on net-next.

- Removed #ifndef and #define of CRCPOLY_LE as part of the patch to
disable VLAN filtering in promiscuous mode
- Reworked changes to xgbe_setup_tc to resolve conflicts with commit

Currently the auto-negotiation interrupt handling disables the irq
instead of masking off the interrupts. This was done because the phy
library was originally used to read and write the PCS registers, which
could not be performed in interrupt context. Now that the phy library is
no longer used to read and write the PCS registers the interrupts can be
masked off in the interrupt service routine eliminating the need to call
disable_irq/enable_irq. This also requires changing the protection mutex
to a spinlock.

The driver is checking the pfc_en field of the ieee_pfc structure to
determine whether to associate a priority with a traffic class. This is
incorrect since the pfc_en field is for determining if PFC is enabled
for a traffic class.
The association of priority to traffic class does not depend on whether
the traffic class is enabled for PFC, so remove that check. Also, the
mapping of priorities to traffic classes should be done when configuring
the traffic classes and not the PFC support so move the priority to traffic
class association from xgbe_config_dcb_pfc to xgbe_config_dcb_tc.

Pull tracing fixes from Steven Rostedt:
"This includes two fixes.
The first is something that has come up a few times and has been
worked out individually, but it's come up now enough that the problem
should be generic. Tracepoints are protected by RCU sched. There are
several tracepoints within core infrastructure like kfree(). If a
tracepoint is called when the CPU is going down, or when it's coming
up but has yet to be recognized by RCU, a RCU warning is triggered.
This is a true bug as that tracepoint is not protected by RCU.
Usually, this is taken care of by testing for cpu online as a
tracepoint condition. But as this is happening more often, moving it
from a individual tracepoint to a check in the tracepoint
infrastructure is more robust.
Note, there is now a duplicate of a cpu online test, because this
update does not remove the individual checks. But the overhead is
small enough that the removal can be done in another release.
The second change is strange linker breakage due to the branch
tracer's builtin_constant_p() check failing, and treating the
condition as a variable instead of a constant. Arnd Bergmann found
that this can be fixed by testing !!(cond) instead of just (cond)"

We get this right for queue_discard_max_show but not max_hw_show. Follow the
same pattern as queue_discard_max_show instead so that we don't truncate.
