Introduce the ice_vf_lib.c file along with the ice_vf_lib.h and ice_vf_lib_private.h header files. These files will house the generic VF structures and access functions. Move struct ice_vf and its dependent definitions into this new header file. The ice_vf_lib.c is compiled conditionally on CONFIG_PCI_IOV. Some of its functionality is required by all driver files. However, some of its functionality will only be required by other files also conditionally compiled based on CONFIG_PCI_IOV. Declaring these functions used only in CONFIG_PCI_IOV files in ice_vf_lib.h is verbose. This is because we must provide a fallback implementation for each function in this header since it is included in files which may not be compiled with CONFIG_PCI_IOV. Instead, introduce a new ice_vf_lib_private.h header which verifies that CONFIG_PCI_IOV is enabled. This header is intended to be directly included in .c files which are CONFIG_PCI_IOV only. Add a #error indication that will complain if the file ever gets included by another C file on a kernel with CONFIG_PCI_IOV disabled. Add a comment indicating the nature of the file and why it is useful. This makes it so that we can easily define functions exposed from ice_vf_lib.c into other virtualization files without needing to add fallback implementations for every single function. This begins the path to separate out generic code which will be reused by other virtualization implementations from ice_sriov.h and ice_sriov.c Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Konrad Jankowski <konrad0.jankowski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
