Intel Wired LAN Driver Updates 2014-12-06

This series contains updates to i40e and i40evf.

Shannon provides several patches to cleanup and fix i40e.  First removes
an unneeded break statement in i40e_vsi_link_event().  Then removes
some debug messages that really do not give any useful information and
ends up getting printed every service_task loop, which fills the logfile
with noise when AQ tracing is enabled.  Updates the aq_cmd arguments to
use %i which is much more forgiving and user friendly than the more
restrictive %x, or %d.  Fixes the netdev_stat macro, where the old
xxx_NETDEV_STAT() macro was defined long before the newer
rtnl_link_stats64 came into being, and just never got updated.
Getting the pf_id from the function number had an issue when
when the PF was setup in passthru mode, the PCI bus/device/function
was virtualized and the number in the VM is different from the number in
the bare metal.  This caused HW configuration issues when the wrong pf_id
was used to set up the HMC and other structures.  The PF_FUNC_RID register
has the real bus/device/function information as configured by the BIOS,
so use that for a better number.

Carolyn adds additional text description for the base pf0 and flow
director generated interrupts, since these interrupts are difficult
to distinguish per port on a multi-function device.

Jacob resolves an issue related to images with multiple PFs per
physical port.  We cannot fully support 1588 PTP features, since only
one port should control (i.e. write) the registers at a time.  Doing
so can cause interference of functionality.

Anjali provides several updates to i40e, first adds the Virtual Channel
OP event opcode for CONFIG_RSS, so that the Virtual Channel state
machine can properly decipher status change events.  Then updates the
driver to add (and use) i40e_is_vf macro for future expansion when new
VF MAC types get added.  Adds new update VSI flow to accommodate a
firmware dix with VSI loopback mode.  All VSIs on a VEB should either
have loopback enabled or disabled, a mixed mode is not supported for a
VEB.  Since our driver supports multiple VSIs per PF that need to talk to
each other make sure to enable Loopback for the PF and FDIR VSI as well.

Mitch provides a couple of i40e and i40evf patches.  First updates
i40evf init code more adept at handling when multiple VFs attempt
to initialize simultaneously.

Joe Perches provides a i40e patch which resolves a compile warning
about about frame size being larger than 2048 bytes by reducing the
stack use by using kmemdup and not using a very large struct on the
stack.

v2:
 - Dropped patch 13 & 14 while Mitch reworks the patches based on
   feedback from Ben Hutchings, probably the tryptophan in the turkey
   is to blame for the delay...
 - Added Joe Perches patch which resolves a compile warning about frame
   size
