This uses preprocessor tricks to make sure that a divide by zero
occurs if a struct changes size outside the expected number of
bytes.

This moves a function that is needed for the virtchnl interface
from the i40e PF driver over to the virtchnl.h file.
It was manually verified that the function in question is unchanged
except for the function name and function header, which explains
the slight difference in the number of lines removed/added.

This patch implements the complete version of the virtchnl.h file
with final renames, and fixes the related code in i40e and i40evf.
It also expands comments, and adds details on the usage of
certain fields.
In addition, due to the changes a couple of casts are needed
to prevent errors found by sparse after renaming some fields.

This change updates the arguments passed to the validate function
and fixes the caller, as well as uses the new return values added to
virtchnl.h
One other minor tweak, remove a duplicate set to zero of valid_len.
This is in preparation for moving the function to virtchnl.h.

Before moving this function over to virtchnl.h, move
some driver specific checks that had snuck into a fairly
generic function, back into the caller of the function.

This morphs all the i40e and i40evf references to/in virtchnl.h
to be generic, using only automated methods. Updates all the
callers to use the new names. A followup patch provides separate
clean ups for messy line conversions from these "automatic"
changes, to make them more reviewable.

This patch changes the i40e driver to start using the new virtchnl

This moves a header for i40evf to include/linux/avf/virtchnl.h.
The directory name AVF is an acronym for the Intel(R) Adaptive
Virtual Function.
This first step creates the new file, which is a rename of
drivers/net/ethernet/intel/i40evf/i40e_virtchnl.h to
include/linux/avf/virtchnl.h, and should show up in git
as a rename when using git log --follow.
To keep things building after the move, the changes to the i40evf
driver are made to point to the new include file location.

This drops the i40e_type.h include in anticipation of the next
patch which moves this file to a location where type.h doesn't
exist, and all the places this file is included already include
i40e_type.h before this file.

The dwmac-sun8i is an Ethernet MAC that supports 10/100/1000 Mbit
connections. It is very similar to the device found in the Allwinner
H3, but lacks the internal 100 Mbit PHY and its associated control
bits.
This adds the necessary bits to the Allwinner A64 SoC .dtsi, but keeps
it disabled at this level.
