ice: introduce ice_vf_lib.c, ice_vf_lib.h, and ice_vf_lib_private.h 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>

ice: remove PF pointer from ice_check_vf_init The ice_check_vf_init function takes both a PF and a VF pointer. Every caller looks up the PF pointer from the VF structure. Some callers only use of the PF pointer is call this function. Move the lookup inside ice_check_vf_init and drop the unnecessary argument. Cleanup the callers to drop the now unnecessary local variables. In particular, replace the local PF pointer with a HW structure pointer in ice_vc_get_vf_res_msg which simplifies a few accesses to the HW structure in that function.
