[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to ixgbe and igb.

The ixgbe changes contains 2 patches from the community, one which is a
fix from akepner to fix a issue where netif_running() in shutdown was
not done under rtnl_lock.  The other community fix from Joe Perches
cleans up #ifdef CONFIG_DEBUG_FS which is no longer necessary.  The
last ixgbe patch, from Jacob Keller, adds support for WoL on 82559
SFP+ LOM.

The remaining patches are against igb, 10 of which were previously
submitted in a pull request where changes were requested.

The following igb patches:
 igb: Support for 100base-fx SFP
 igb: Support to read and export SFF-8472/8079 data
are v2 based on feedback from Dan Carpenter and Ben Hutchings in
the previous pull request.

The largest set of changes are in my patch to cleanup code comments
and whitespace to align the igb driver with the networking style of
code comments.  While cleaning up the code comments, fixed several
other whitespace/checkpatch.pl code formatting issues.

Other notable igb patches are EEE capable devices query the PHY to
determine what the link partner is advertising, added support for
i354 devices and added support for spoofchk config.

The following are changes since commit c1cb0d3b569b1d21ada8666efb42dfd437617a09:
  Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next

[net-next 01/15] ixgbe: in shutdown, do netif_running() under rtnl_lock

[Jeff Kirsher]

From: akepner <akepner@riverbed.com>

During shutdown it's possible for __dev_close() (which holds
rtnl_lock) to clear the __LINK_STATE_START bit, and for ixgbe
to then read that bit (without holding rtnl_lock), and then
not fail to free irqs, etc. The result is a crash like this:

[net-next 08/15] igb: Mask off check of frag_off as we only want fragment offset

From: Alexander Duyck <alexander.h.duyck@intel.com>

We were incorrectly checking the entire frag_off field when we only wanted the
fragment offset.  As a result we were not pulling in TCP headers when the DNF
flag was set.

To correct that we will now check for frag off using the IP_OFFSET mask.

We only need the adapter pointer in the case of ptp.  As such we can pull the

the temptation of accessing the adapter pointer in the fast path.

[net-next 10/15] igb: Use rx/tx_itr_setting when setting up initial value of itr

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

It turns out that the InterruptThrottleRate module parameter was only
having the effect of locking the ITR at the starting ITR value. This was
because the values stored in rx_itr_setting and tx_itr_setting were being
ignored when configuring the initial itr_val of the q_vector.

Pulled, thanks Jeff.

And, as always, thanks for the detailed cover letter.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e and i40evf.

Kevin updates the i40e and i40evf driver i40e_check_asq_alive() to ensure
the length register offset is non-zero which indicates that the software
has initialized the admin queue.  Also removes PCTYPE definitions which are
now reserved.

Mitch enables descriptor prefetch for rings belonging to the virtual function.
Also configures the VF minimum transmit rate to 50 Mbps rather than 0 which was
be interpreted as no limit at all.  Mitch found in order for the VF to achieve
its programmed transmit rate, we need to set the max credit value to 4.
Lastly fixes a Tx hang and firmware crash that happens after setting the MTU
on a VF by not using the RESETTING state during reinit, this is because
the RESETTING state means that a catastrophic hardware bad thing is happening
and the driver needs to tiptoe around and not use the admin queue or registers.
A reinit is no big deal and we can use the admin queue (and we should) so
do not set the state to RESETTING during reinit to resolve the bug.

Akeem changes the declaration of the transmit and receive rings inside
several loops to eliminate declaring the same ring every time for the
duration of the loop and declares them just once before the loop.  Also fixes
the driver to clear the recovery pending bit if pf_reset fails instead of
falling through the setup process.

Anjali makes a change based on feedback from Ben Hutchings that cmd->data
needs to be reported in ETHTOOL_GRXCLSRLCNT and use a helper function to
calculate the total filter count.

Jesse removes storm control since the storm control features are not apart
of the hardware and were mistakenly left in the code.

Greg changes tx_lpi_status and rx_lpi_status from bool to u32 to avoid
sparse errors.

Shannon adds the clear_pxe AdminQ API call to tell the firmware that the
driver is taking over from PXE.  In addition, relaxes the firmware API
check to allow more flexibility in handling newer NICs and NVMs in the field.

Vasu ensures that FCoE is disabled for MFP modes since it is not supported
by overriding the hardware FCoE capability.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to e1000, e1000e, ixgbe and i40evf.

Emil provides a fix for ixgbe so that non-fiber devices with MNG FW enabled
are able to link at 100Mbps.

Jacob provides several changes for ixgbe, most of which are PTP related.
Renames ixgbe_ptp_enable() to ixgbe_ptp_feature_enable() to better reflect
the functions purpose.  Extracts the hardware setup logic for the PTP
hardware bits from the ixgbe_ptp_set_ts_config() to enable future work for
the ixgbe_ptp_reset().  Maintain the hwstamp configuration through a reset
and extracts the creation of the PTP clock device from ptp_init() in order
to properly handle a suspend/resume cycle and only calls it if we don't
already have a ptp_clock pointer.

David provides a patch to expend the e1000e driver to turn on unicast
PROMISC when there is failure to write to a shared receive address register.
The fix update_phy_task() for 82579 is expanded to include newer PHYs as well
so that the dev_spec->eee_lp_ability has the correct value when going into
SX states.

Todd provides a e1000e fix an errata for 82574/82583 where it is possible
bad bits are read from SYSTIMH/L so check to see that the time is
incrementing at a reasonable rate and is a multiple of the time incremental
value.  Removes a redundant igb PHY power down register write.

Andi Kleen out of lines two write functions for e1000e to save 30k text size.

Tobias Klauser converts the e1000 and i40evf drivers to use the
is_broadcast_ether_addr() and is_multicast_ether_addr().

Pulled, thanks Jeff.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e and i40evf.

Shannon makes minor changes to the AdminQ interface to bring it up to
date.  Removes the hard coding of stats struct size in ethtool, in prep
for adding data fields which are configuration dependent.

Catherine removes some unused and unneeded PCI bus defines.

Jesse fixes the copyright headers and finishes up the removal of the PTP
Tx work functionality which allows us to rely on the Tx timesync interrupt.

Mitch provides a number of fixes and cleanups for i40e/i40evf based on
suggestions from Ben Hutchings.  First is to use a macro parameter for
ethtool stats instead of just assuming that a valid netdev variable
exists.  Second is not to tell ethtool that the VF can do 10GbaseT, when
it really has no idea what its link speed is, so set the supported value
to 0 instead.  Make the ethtool_ops structure constant since it is
extremely unlikely to change at runtime.  Ethtool consistently reports
0 values for our ITR settings because we never actually use them, so
fix this by setting the default values to the specified default values.

Greg avoids a compile error by wrapping the call to i40e_alloc_vfs() in
CONFIG_PCI_IOV because the function itself is wrapped in the same
conditional compile block.

Alexander Gordeev updates the driver to use the new pci_enable_msi_range()
and pci_enable_msix_range() or pci_enable_msi_exact() and
pci_enable_msix_exact().

Jean Sacren provides a fix where the wrong error code was being passed to
i40e_open().

Pulled, thanks a lot Jeff.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e and i40evf.

Jacob provides a i40e patch to remove ptp_tx_work() because it conflicts
with the interrupt-based handler and will cause spurious warning messages
to be displayed in the kernel log.  Since the hardware can properly trigger
an interrupt, we do not need to poll for an available timestamp in a work
queue any more.

Greg provides two patches for i40e, first to retain the MAC filter list
when changing a port VLAN.  Second fixes an issue where the function to
set the VF MAC address was not taking the port VLAN filter into account
when setting/clearing/resetting the VF's host administered MAC address.

Mitch provides three patches for i40evf, first adds support for getting
and setting RSS hashing options, RSS LUT entries, and getting the number
of device channels from ethtool.  Fixes a panic that woudl occur in the VF
if the PF driver failed or was removed from the host kernel.

Shannon adds driver version string to the driver version command so that
can be passed down through the firmware to low-level NC-SI functions.

Neerav provides several patches, first redistributes queue vectors after
DCB reconfiguration because the total number of queues that are configured
for a VSI may change based on a change in the total number of TCs enabled
as a result of a change in the DCB configuration based on DCBX.  Second,
allows the driver probe to continue when querying DCB config fails.
Lastly, provides changes to retrieve and store missing link config
information that was not being cached in the struct i40e_link_status.

Kevin provides a couple of patches, first to change a int variable type
to u16 to avoid a typecheck failure.  Second to update a function
parameters to remove an argument which is no longer used.

The following are changes since commit a49eb42a341f1df8fa0f9dc4449f9dd4a3234a2f:

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to e1000e, igb, i40e and i40evf

Anjali provides i40e fix to remove the ATR filter on RST as well as FIN
packets.  Cleans up add_del_fdir() because it was used and implemented
only for the add, so change the name and drop a parameter.  Adds the
ability to drop a flow if we wanted to and adds a flow director
message level to be used for flow director specific messages.  Provide
a fallback debug flow for i40e if the reset fails or the firmware is
unresponsive.

Mitch fixes an issue on i40evf where the Tx watchdog handler was causing
an oops when sending an admin queue message to request a reset because
the admin queue functions use spinlocks.

Greg provides a change to i40e to make the alloc and free queue vector
calls orthogonal.

Shannon fixes i40e to verify the eeprom checksum and firmware CRC status
bits, and shutdown the driver if they fail.  This change stops the
processing of traffic, but does not kill the PF netdev so that the
NVMUpdate process still has a chance at fixing the image.  Also provides
a fix to make sure the VSI has a netdev before trying to use it in
the debugfs netdev_ops commands.

Jakub Kicinski provides patches for e1000e and igb to fix a number issues
found in the PTP code.

Pulled, thanks Jeff.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to e100, igb, igbvf, ixgbe and ixgbevf.

Stefan adds a igb patch to enable the ability strip VLAN header information
for packets bound for a VM on i350 hardware.

Joe Perches provides patches for e100, igb, igbvf, ixgbe and ixgbevf to
convert the use of __constant_<foo> to just <foo> to align with the rest
of the kernel.

Don provides two fixes for ixgbe, first resolves a link issue with DA
cables where we were not always freeing the firmware/software semaphore
after grabbing it.  Second stops caching whether the management firmware
was enabled, however since this is not static, we really need to verify
with each check.

Jacob provides six fixes/cleanups for ixgbe, most notably, correct
the stop_mac_link_on d3() to check the Core Clock Disable bit before
stopping link and to fully check to see if manage firmware is running or
could be enabled before bringing down the link.  Fix flow control
auto-negation for KR/KX/K4 interfaces, since setting up MAC link, the
cached autoc value and current autoc value were being incorrectly used to
determine whether link reset is required.

Emil provides a fix for ixgbe where there was a chance for aggressive
start_ndo_zmit() callers to sneak packets between enabling the Tx queues
and the link coming up.  To resolve this, move the call to enable Tx
queues to after the link is established.

The following are changes since commit a9baf10aafe7001501189099df4b91f90739e182:
  qeth: Fix IP version detection for VLAN traffic
and are available in the git repository at:

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to e1000e, ixgbevf and igb.

Majority of this series contains fixes and cleanups to e1000e,
most notably are:

Todd provides a fix to PTP in e1000e which adds a lock in e1000e_phc_adjfreq
to prevent concurrent changes to TIMINCA and SYSTIMH/L.  Then provides an
igb fix to use ARRAY_SIZE for array size calculation.

David provides the remaining e1000e which contain:
 - cleanup of pointer references that are no longer used
 - fix an issue on systems with Management Engine enabled with the
   ethernet cable unplugged
 - fix an issue on 82579 where enabling EEE LPI sooner than one second
   after link up causes link issues on some switches
 - refactor the power management flows to prevent the suspend path from
   being executed twice when hibernating
 - refactor the runtime power management to fix interfering with the
   functionality of Energy Efficient Ethernet when enabled and to fix
   the device from repeatedly flip between suspend and resume with the
   interface administratively downed
 - enable the feature PHY Ultra Low Power Mode which is a power saving
   feature that reduces the power consumption of the PHY when a cable is
   not connected
 - fix the ethtool offline tests for 82579 parts
 - fix SHRA register access for 82579 parts which was introduced by
   previous commit c3a0dce35af0 "e1000e: fix overrun of PHY RAR array"

Florian provides a fix for ixgbevf where skb->pkt_type was being checked
like a bitmask, but it is not a bitmask.

Fix an issue reported by Stephen Hemminger where there was a warning
about code defined but never used if IGB_HWMON is not defined.

The following are changes since commit 37147652cfaa20a87ead9bb04aec1834b40c5c97:
  6lowpan: reassembly: fix return of init function

Pulled, thanks Jeff.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e only.

Anjali provides a fix where interrupts were not being re-enabled on ICR0
even though they were auto masked by hardware.  Then provides a fix to
cleanup RSS initialization because it was doing some extra work, so
remove the extra work and any bugs it created when managing number of
queues.  Since hardware requires a full packet template to be pointed to
when adding hardware flow filters, add the template and use it for
programming filters.

Jesse provides a fix to replace the use of driver specific defines with
kernel ETH_ALEN defines.  Then disables packet split because with the
use of GRO, we do not need the extra bus overhead.  Fixes spelling
error in code comment.

Kamil provides a fix for the driver where the hardware expects the MAC
address in a very specific format and the driver was filing the data
incorrectly.

Mitch provides a fix to resolve a panic on reset by adding checks to
VSI->rx_rings.  Then shortens alloc_rx_buff_failed and
alloc_rx_page_failed variables since both part of an RX specific
structure so just remove the _rx part of the name.  Then fixes
badly formatted lines, long lines and mis-formatted lines.

Shannon provides a fix to call AQ to release any reservation held by this
PF on the NVM resource lock on startup, in order to clear anything that
might have been left over from a previous run.  Then removes interrupt on
AQ error since nearly everything we do is synchronous, using the
interrupt-on-error bit is unnecessary and causing unneeded interrupts.
Adds code to handle the ability to send messages among the physical
function interfaces by the admin queue.

Catherine sets the MFP flag earlier in software init and uses that flag
to decide if other hardware work-arounds are required which turns
off flow director in MFP mode.

The following are changes since commit 54b553e2c16001d13e0186cad2531764065f9a1b:

1.8.3.1

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e only.

Anjali adds more functionality to debugfs to assist development and
testing of admin queue commands.

Greg makes sure broadcast promiscuous is disabled by default, otherwise
VLAN tagged packets out of the assigned VLAN domain are received.  Also
provides a fix when the 8021q driver is loaded, so that VLAN 0 tagged
packets are accepted so that upper layers can interpret the priority
bits. Then provides a fix to let the VF to request the PF to set its
already assigned MAC address without generating an error.  Greg also
adds helper functions to enable or disable internal switch loopback
when VFs are created or destroyed via the sysfs interface.

Shannon provides most of the changes, where he adds code to ensure
that the hardware waits to make sure that the firmware is ready as well
after reset.  Also updates the code to use the new features in the
firmware.  Provides a fix while in MFP mode where resources are
reduced, so use a smaller range of test registers than when in SFP mode.
Moves the PF ID initialization code to earlier in the driver
initialization function since a few operations need the information
before the first PF reset is called.  Shannon adds a check for MAC
type before reading anything from the registers to ensure we dealing
with the correct MAC type.  Then reworks Shadow RAM read word/buffer
functions as to not block whole NVM resources for SR read operations.

Mitch lastly provides a fix to correctly setup ARQ descriptors in
the cleanup code.

Catherine bumps the driver version due to all the recent changes.

The following are changes since commit 83111e7fe85f2dc8b61e463c71b971f4998d8e53:
  netfilter: Fix build failure in nfnetlink_queue_core.c.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e only.

Majority of this series contains patches from Greg and Mitch to fix
up or add functionality to the PF/VF driver interactions.  Notably,
a fix for SR-IOV VF port VLAN which resolved the problem of port VLAN
configurations not being persistent across VF driver loads and unloads
and enable/disable of the feature.  Also do not enable the default port
on the VEB, which is designed only to bridge the PF to an Open vSwitch
or bridge.  Another fix to resolve a possible memory corruption
condition where ARQ messages are written to random memory locations.
Fix a problem where the 'ip link show' command would display stale
link address information after the link address was set via the 'ip
link set' command.

Anjali provides several patches, one which saves information that can
be used while cleaning the Tx ring and useful in detecting Tx hangs.
Then provides a fixes to the admin queue shutdown function to ensure
we are shutting down the queue in the shutdown path and ensure ASQ is
alive before issuing the admin queue command.

Shannon provides a fix for get/update vsi params where the incorrect
struct was being used.

The following are changes since commit b912b2f8fc71df4c3ffa7a9fe2c2227e8bcdaa07:

Looks fine, pulled, thanks Jeff.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e only.

Anjali provides two cleanups to remove unnecessary code and a fix
to resolve debugfs dumping only half the NVM.  Then provides a fix
to ethtool NVM reads where shadow RAM was used instead of actual
NVM reads.

Jesse provides a couple of fixes, one removes custom i40e functions
which duplicate existing kernel functionality.  Second fixes constant
cast issues by replacing __constant_htons with htons.

Mitch provides a couple of fixes for the VF interfaces in i40e.  First
provides a fix to guard against VF message races with can cause a panic.
Second fix reinitializes the buffer size each time we clean the ARQ,
because subsequent messages can be truncated. Lastly adds functionality
to enable/disable ICR 0 dynamically.

Vasu adds a simple guard against multiple includes of the i40e_txrx.h
file.

Shannon provides a couple of fixes, first fix swaps a couple of lines
around in the error handling if the allocation for the VSI array fails.
Second fixes an issue where we try to free the q_vector that has not
been setup which can panic the kernel.

David provides a patch to save off the point to memory and the length
of 2 structs used in the admin queue in order to store all info about
allocated kernel memory.

Neerav fixes ring allocation where allocation and clearing of rings
for a VSI should be using the alloc_queue_pairs and not num_queue_pairs.
Then removes the unused define for multi-queue enabled.

The following are changes since commit a1d4b03a076d95edc88d070f7627a73ab80abddc:

Disregard this pull request.  I overlooked a patch that needs to either
precede this series or get added to the series for VXLAN.

I will be sending out a v2 with the necessary patch added.

[Jeff Kirsher]

This series contains updates to i40e only.

Anjali provides a patch to prevent messages from stray HMC events, except
at interrupt message level, and refactors the HMC error handling.

Catherine adds routines in probe to populate/check PCI bus speed and width,
then verify we are in a 8GT/s x8 PCIe slot and warn when we are not.

Shannon adds Wake-on-LAN support for i40e, fixes curly brace use as well as
return type for i40e_vsi_clear_rings().  Lastly implements the set_settings
and set_pauseparam ethtool functionality.

Joseph implements receive offload for VXLAN for i40e, where the hardware
supports checksum offload/verification of the inner/outer header.

Mitch provides the bulk of the changes, where he refactors the VF reset
code so that it works on real hardware.  Then does code cleanup by
calling existing functions to enable and disable queues for VFs and
remove unused functions.  Removes a unnecessary log messages that are
seen at every VF reset, for example complaining about disabling queues
that are already disabled.  Fixes an error return when the VF asks to
add an invalid MAC address and if the VF sends a bad message, make it
more informative about what is actually going on.

Jesse refactors the LED function to flash LED lights correctly.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e only (again).

Jesse provides a fix for when tx_rings structure is NULL and we do not want
to panic. Then refactors the flow control set up and disables L2 flow control
by default.  Provides some trivial fixes as well as prevent compiler warnings.
Then to align to similar behaviour in ixgbe, use the total number of CPUs in
the system to suggest the number of transmit and receive queue pairs.

Shannon provides a i40e ethtool fix to get some more reasonable information
reports back out to the ethtool.  In addition, fixes PF reset after offline
test, where it reorders the test to put the register test last as it is the
only one that needs a reset, and we wait to trigger the reset until after we
clear the testing bit.  Lastly provides basic support for handling suspend
and resume for now, later on Wake-On-LAN support will be added.

Elizabeth Kappler adds netdev ops helper function.

Anjali provides changes to tell the stack about our actual number of queues
in order for RFS/RPS/XFS to work correctly.  Then provides several patches to
implement dynamically changing the queue count for the main VSI.  Adds
basic support for get/set channels for RSS so that the number of receive and
transmit queue pair can be changed via ethtool.  Cleans up the use of
rtnl_lock in the reset patch since it runs from a work time.

Neerav Parikh cleans up the VF interface to remove FCoE code as this
feature will not be supported on VF interfaces.

The following are changes since commit c45f812f0280c13f1b7992be5e0de512312a9e8f:

[Jeff Kirsher]

This series contains updates to i40e only.

Christopher Pau provides a patch to set pf_id based on device and
function numbers since NICs with ARI enabled can have function
numbers larger than 8.

Anjali provides 3 i40e patches to update hardware defines to keep
in sync with hardware updates.

Shannon provides the majority of i40e patches, with 7.  First patch
clears the admin queue head and tail registers during admin queue
shutdown. Then simplifies the admin queue head-tail-len setups to
use more virtual registers.  Provides several patches to cleanup
and fix driver load and reset procedures to make more robust.  Lastly,
provides an ethtool test for interrupts using the software interrupt.

Mitch provides some i40e patches which fixes up VF code in the PF
driver, specifically the number of vectors per VF are reported by the
hardware does not include vector 0, so we need to account for this
when checking.  In addition, cleans up debugging messages.

Kamil provides an i40e patch to fix the diagnostics test by restricting
the diagnostic test length.

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to igb and e1000e.

Akeem provides 3 igb patches, the first resets the link when EEE is enabled
or disabled if the link is up.  His second patch changes a register read
which normally stores of the read value to "just-read" so that hardware
can accurately latch the register read.  Lastly, he adds rcu_lock to avoid
a possible race condition with igb_update_stats function.

Mitch provides a fix for SR-IOV, where MSI-X interrupts are required, so
make sure that MSI-X is enabled before allowing the user to turn on SR-IOV.

Alex's igb patch make it so that we limit the lower bound for max_frame_size
to the size of a standard Ethernet frame.  This allows for feature parity
with other Intel based drivers such as ixgbe.

Carolyn adds a SKU for a flashless i210 device and a fix for get_fw_version()
so that it works for all parts for igb.  In addition, she has 2 igb patches
to refactor NVM code to accommodate devices with no flash.  Lastly, she
adds code to check for the failure of pci_disable_link_state() to attempt
to work around a problem found with some systems.

Laura provides the remaining 2 igb patches.  One removing the hard-coded
value for the size of the RETA indirection table, and creates a macro instead
for the RETA indirection table.  The second adds the ethtool callbacks
necessary to change the RETA indirection table from userspace.

Bruce fixes a whitespace issue in a recent commit and resolves a jiffies
comparison warning by using time_after().

Li provides a fix for e1000e to avoid a kernel crash on shutdown by adding
one more check in e1000e_shutdown().  This is due to e1000e_shutdown()
trying to clear correctable errors on the upstream P2P bridge, when under
some cases we do not have the upstream P2P bridge.

The following are changes since commit 84ce22df92f5cf9ecb76d53f4bf5f6d504684540:

[net-next 00/15][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to ixgbe and pci.

The first patch for ixgbe from Greg Rose is the second submission.  The
first submission of "ixgbe: Retain VLAN filtering in promiscuous + VT
mode" had a typo, which Joe Perches pointed out and is fixed in this
submission.

Alex updates the ixgbe driver to use the generic helper pci_vfs_assigned
instead of the driver specific function ixgbe_vfs_are_assigned.

Don Skidmore provides 4 patches for ixgbe, the first being a fix for
flow control ethtool reporting.  Originally ixgbe_device_supports_autoneg_fc()
was expected to be called by only copper devices, which lead to false
information being displayed via ethtool.  Two other patches add support
for fixed fiber for SFP+ devices and the addition of a quad-port x520
adapter.  The last patch simply bumps the driver version.

Emil Tantilov provides 3 fixes for ixgbe, two of which resolve
semaphore lock issues.  The third fix resolves several issues in the
previous implementation of the SFF data dumps of SFP+ modules.

The remaining ixgbe and pci patches are from Jacob Keller.  The pci
patches exposes bus speed, link speed and bus width so that drivers
can take advantage of this information.  In addition, adds a pci function
which obtains minimum link width and speed.  Jacob also provides the
ixgbe patch to incorporate the pci function. He provides a patch that
fixes a lockdep issue created due to ixgbe_ptp_stop always running
cancel_work_sync even if the work item had not been created properly with
INIT_WORK. This issue was found and reported by Stephen Hemminger.

The following are changes since commit fe6f700d6cbb7e8a61711e325f53d9c9e0a42a4c:

This series contains updates to ixgbevf and e1000e.

Alex's ixgbevf patch is meant to address several race issues that become
possible because next_to_watch could possibly be set to a value that shows
that the descriptor is done when it is not.  In order to correct that we
instead make next_to_watch a pointer that is set to NULL during cleanup,
and set to the eop_desc after the descriptor rings have been written.

Stephen's ixgbevf patch makes the PCI id table a const and reformats the
table to match what the ixgbe driver does.

The remaining 13 patches from Bruce are cleanup patches for e1000e to
resolve checkpatch.pl warnings/errors, removing blank lines where
necessary and fix code formatting.

The following are changes since commit 7f0e44ac9f7f12a2519bfed9ea4df3c1471bd8bb:
  ipv6 flowlabel: add __rcu annotations
and are available in the git repository at:
