This restricts the device drivers to be reused for other domain numbers. Getting ready to remove pci_get_bus_and_slot() function in favor of pci_get_domain_bus_and_slot(). Introduce bnx2x_vf_domain() function to extract the domain information and save it to VF specific data structure. Use the saved domain value while calling pci_get_domain_bus_and_slot().
