This patch contains the main driver header files, containing structures
and data types specific to the linux driver.
i40e_osdep.h contains some code that helps us adapt our OS agnostic code
to Linux.

This PCI-E SR-IOV virtual function (VF) driver is dependant upon the
physical function (PF) driver (i40e) for nearly all of its hardware
configuration. Requests from the VF driver are passed to the PF using
the hardware's Admin Queue.
This patch contains the functionality for communicating with the PF
driver. Because of the delay inherent in this communications channel,
most of the replies from the PF driver are handled asynchronously. The
exceptions are the "send API version" and "get VF config" messages,
which busy-wait because they are done so early during init that
interrupts are not yet configured.

This patch contains the ethtool interface and related functionality.
Since the VF driver is mostly unaware of link, much of that
functionality is unused. The driver implements ethtool hooks for
statistics, driver info, and some basic non-link-related driver
settings.

This file contains the transmit, receive, and NAPI functionality.
Some of the functions in this module are extracted from the i40e driver
but functions that are not appropriate for virtual function devices have
been removed.

This is the driver for the Intel(R) XL710 X710 Virtual Function.
This patch contains the main driver entry points, but does not include
transmit and receive or ethtool functionality, which are presented as
separate patches in this series.
