We will be adding support for the SR-IOV and driver might be then running, in addition to existing non-virtualized bare-metal mode, also in Physical Function (PF) or Virtual Function (VF) mode. Since these additional modes require some changes to the driver, define enum flag to represent different SR-IOV modes and add a function where we will detect the actual mode in the runtime. We start with a forced bare-metal mode as it is sufficient to enable basic functionality and ensures no impact to existing code.
