[net-next 00/14][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to ixgbe, ixgbevf, e1000e, igb and i40e.

Jacob converts the ixgbe low_water into an array which allows the
algorithm to output different values for different TCs and we can
distinguish between them.  Removes vlan_filter_disable() and
vlan_filter_enable() in ixgbe so that we can do the work directly in
set_rx_mode().  Changes the setting of multicast filters only when
the interface is not in promiscuous mode for multicast packets in
ixgbe.  Improves MAC filter handling by adding mac_table API based
on work done for igb, which includes functions to add/delete MAC
filters.

Mark changes register reads in ixgbe to an out-of-line function since
register reads are slow.

Emil provides a ixgbevf patch to update the driver description since
it supports more than just 82599 parts now.

David provides several cleanup patches for e1000e which resolve some
checkpatch issues as well as changing occurrences of returning 0 or 1 in
bool functions to returning true false or true.

Carolyn provides several cleanup patches for igb which fix checkpatch
warnings.

Mitch provides a fix for i40evf where the driver would correctly allow
the virtual function link state to be controlled by 'ip set link', but
would not report it correctly back.  This is fixed by filling out
the appropriate field in the VF info struct.

The following are changes since commit fd0d192be6e814495aec91f357b5801afc3b6262:
  Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next

[net-next 01/14] ixgbe: convert low_water into an array

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

Since fc.high_water is an array, we should treat low_water as an array
also. This allows the algorithm to output different values for different
TCs, and then we can distinguish between them. In addition, this patch
changes one path that didn't honor the return value from ixgbe_setup_fc.

[net-next 02/14] ixgbe: Use out-of-line function for register reads

[Jeff Kirsher]

From: Mark Rustad <mark.d.rustad@intel.com>

Register reads are slow, so don't inline them.

Size before:
   text	   data	    bss	    dec	    hex	filename
 226337	   8280	    552	 235169	  396a1	ixgbe.ko

Size after:
   text	   data	    bss	    dec	    hex	filename
 194578	   8280	    552	 203410	  31a92	ixgbe.ko

for about a 14% reduction in text size.

[net-next 03/14] ixgbe: remove vlan_filter_disable and enable functions

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

Previously these functions handled stripping setup as well, but this has
already been removed from these functions. Rather than encapsulating
this into a function, we can just do the work directly in set_rx_mode.

[net-next 04/14] ixgbe: change handling of multicast filters

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

In line with changes done by Alex Duyck regarding unicast filters, we
now only set multicast filters when the interface is not in promiscuous
mode for multicast packets. This also has an impact on the RAR usage
such that SR-IOV has some RARs reserved for its own usage.

[net-next 05/14] ixgbe: improve mac filter handling

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

Add mac_table API based on work done for igb, which includes functions
to add and delete mac filters. This simplifies code for various entities
that use MAC filters such as VMDQ, SR-IOV, MACVLAN, and such.

[net-next 14/14] i40e: report VF link state correctly

[Jeff Kirsher]

From: Mitch Williams <mitch.a.williams@intel.com>

Although the driver would correctly allow the VF link state to be
controlled by 'ip set link', it would not report it correctly back.

Fix this by filling out the appropriate field in the vf info struct.

[net-next 00/14][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e, ixgbevf, ixgbe and igb.

Don provides an ixgbevf patch to add DCB configuration into the queue
setup so that we won't have to allocate queues in a separate place when
enabling DCB.

Guenter Roeck provides 2 patches for ixgbe to simplify the code by
attaching hwmon sysfs attributes to hwmon device instead of PCI device.
Also fix an issues where the temperature sensor attribute index was
being started with the value 0 and not 1 as per the hwmon API.

Carolyn provides igb patches to fix queue allocation method to
accommodate changes during runtime.  This includes changing how the
driver initializes MSIx and checks for MSIx configuration to make it
easier to reconfigure the device when queue changes happen at runtime.

Neerav and Shannon fixes i40e debugfs commands that dump hex information
by using print_hex_dump().

Shannon provides several i40e fixes which include the prevention of
null pointer exception in the dump descriptor by checking that rings
were allocated before trying to reference them.  Fixed up a couple of
scanfs to accept various base numbers instead of silently requiring hex.

Anjali fixes up i40e where the incorrect defines were being used for
misc interrupts.

Alan Cox provides a fix for i40e where we assume that the resulting
buffer is zero terminated when we then re-use it.  The sscanf is limited
to 512 bytes but needs to be 511 to allow for a terminator.

Stephen Hemminger fixes i40e by making local functions static and removes
unused code (i40e_aq_add/remove_vlan() functions).

The following are changes since commit 02d5cb5bb20b9d34db20860aad1891cd9b8e81d5:
  qeth: Accurate ethtool output

[net-next 00/14][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e only.

Jacob provides a i40e patch to get 1588 work correctly by separating
TSYNVALID and TSYNINDX fields in the receive descriptor.

Jesse provides several i40e patches, first to correct the checking
of the multi-bit state.  The hash is reported correctly in the RSS
field if and only if the filter status is 3.  Other values of the
filter status mean different things and we should not depend on a
bitwise result.  Then provides a patch to enable a couple of
workarounds based on revision ID that allow the driver to work
more fully on early hardware.

Shannon provides several i40e patches as well.  First sets the media
type in the hardware structure based on the external connection type.
Then provides a patch to only setup the rings that will be used.  Lastly
provides a fix where the TESTING state was still set when exiting the
ethtool diagnostics.

Kevin Scott provides one i40e patch to add a new flag to the i40e_add_veb()
which allows the driver to request the hardware to filter on layer 2
parameters.

Anjali provides four i40e patches, first refactors the reset code in
order to re-size queues and vectors while the interface is still up.
Then provides a patch to enable all PCTYPEs expect FCoE for RSS.  Adds
a message to notify the user of how many VFs are initialized on each
port.  Lastly adds a new variable to track the number of PF instances,
this is a global counter on purpose so that each PF loaded has a
unique ID.

Catherine bumps the driver version.

The following are changes since commit 0d74c42f788caf3cad727c61c490d9459bc8918b:
  ether_addr_equal: Optimize implementation, remove unused compare_ether_addr
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next master

Anjali Singhai Jain (4):

[net-next 00/14][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to i40e only.

Jesse provides 6 patches against i40e.  First is a patch to reduce
CPU utilization by reducing read-flush to read in the hot path.  Next
couple of patches resolve coverity issues reported by Hannes Frederic
Sowa <hannes@stressinduktion.org>.  Then Jesse refactored i40e to cleanup
functions which used cpu_to_xxx(foo) which caused a lot of line wrapping.

Mitch provides 2 i40e patches.  First fixes a panic when tx_rings[0]
are not allocated, his second patch corrects a math error when
assigning MSI-X vectors to VFs.  The vectors-per-vf value reported
by the hardware already conveniently reports one less than the actual
value.

Shannon provides 5 patches against i40e.  His first patch corrects a
number of little bugs in the error handling of irq setup, most of
which ended up panicing the kernel.  Next he fixes the overactive
IRQ issue seen in testing and allows the use of the legacy interrupt.
Shannon then provides a cleanup of the arguments declared at the
beginning of each function.  Then he provides a patch to make sure
that there are really rings and queues before trying to dump
information in them.  Lastly he simplifies the code by using an
already existing variable.

Catherine provides an i40e patch to bump the version.

The following are changes since commit 7cc7c5e54b7128195a1403747a63971c3c3f8e25:
  net: Delete trailing semi-colon from definition of netdev_WARN()

[net-next 00/14][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to ixgbe, igb and pci.

The ixgbe changes contains a fix to a possible divide by zero by bailing
out of the ixgbe_update_itr() function if the last interrupt timeslice is
zero.  In addition, support is added for the new OCP x520 adapter as well
as LX support for 82599 devices.  Jacob provides a patch to change
variable wol_supported to wol_enabled to better reflect what the code
is actually doing (i.e. checking if WoL is enabled).

Alex adds SRIOV helper function to pci that will determine if a PF
has any VFs that are currently assigned to a guest.

The remaining 8 patches are against igb and contain the following changes:
* implement SERDES loopback configuration for i210 devices by unsetting
  sigdetect bit, so as to fix Ethtool loopback test failure
* add support for the SMBI semaphore for I210/I211 devices
* implement the new generic pci_vfs_assigned helper function (Alex's PCI
  helper function)
* display warning when link speed is downgraded due to Smartspeed
* ensure that VLAN hardware filtering remains enabled when the device is
  in promiscuous mode and VT mode simultaneously
* cleanup dead code in igb
* bump the driver version

The following are changes since commit 95a06161e6b903ad5b96285cb57c8df3b7c8ad34:
  Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next

[net-next 00/14][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to e1000e, ixgbevf, igb and igbvf.
Majority of the patches are code cleanups of e1000e where code
is removed (Yeah!).  The other two e1000e patches are fixes.  The
first is to fix the maximum frame size for 82579 devices.  The second
fix is to resolve an issue with devices other than 82579 that suffer
from dropped transactions on platforms with deep C-states when
jumbo frames are enabled.

The ixgbevf patch is to ensure that the driver fetches the correct,
refreshed value for link status and speed when the values have changed.

The igb and igbvf patches are a solution to an issue Stefan Assmann
reported, where when the PF is up and igbvf is loaded, the MAC address
is not generated using eth_hw_addr_random().

The following are changes since commit a1b1add07fa794974573d93483d68e373edfe7bd:
  gro: Fix kcalloc argument order

[net-next 00/14][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to ixgbe, ixgbevf, igbvf, igb and
networking core (bridge).  Most notably is the addition of support
for local link multicast addresses in SR-IOV mode to the networking
core.

Also note, the ixgbe patch "ixgbe: Add support for pipeline reset" is
v2 based on community feedback.

The following are changes since commit e269ed26d4c9e6da1614709c1bf4c50ff8c8c5b3:
