Intel Wired LAN Driver Updates

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).

therefore it is a bit hard to add and remove a specific

This patch changes how the driver initializes MSIx and checks

When changing number of queues using ethtool's set_channels during runtime,
a queue allocation could fail, which can leave the device in a down state.
In order to preserve the usability of the device in this scenario, this patch
changes the driver to allocate the  number of queues only if they have not
been allocated already. The first allocation is then done for the max number
of queues, which is the default queues for this driver.   With this change,
queue quantity changes are not subject to queue allocation failures.

Simplify the code. Attach hwmon sysfs attributes to hwmon device
instead of pci device. Avoid race conditions caused by attributes
being created after hwmon device registration. Implicitly
(through hwmon API) add mandatory 'name' sysfs attribute.

Other cleanup:

Instead of allocating memory for hwmon attributes, move attributes
and all other hwmon related data into struct hwmon_buff and allocate
the entire structure using devm_kzalloc.

Check return value from calls to igb_add_hwmon_attr() one by one instead
of logically combining them all together.

packet: deliver VLAN TPID to userspace

This patchset enables userspace to get VLAN TPID as well as the VLAN TCI.

After the 802.1AD support, userspace packet receivers (packet dumper,
software switch, and the like) need how to know VLAN TPID in order to
reconstruct original tagged frame.

v4: Simply use sizeof(tp_padding) for zeroing the padding bytes,
    commented by David Laight.
    Use __u16 for tp_vlan_tpid in tpacket_hdr_variant1,
    commented by Daniel Borkmann.

v3: Add a definition which indicates whether tp_vlan_tpid is valid.
    Explicitly define pad bytes for tpacket{2,3}_hdr and pick the area
    for tp_vlan_tpid from the definition.  Commented by David Laight.

v2: Add BUILD_BUG_ON() to make current aligned size of
    struct tpacket{2,3}_hdr clear.  Commented by Ben Hutchings.
