IOV_GET_VER_INFO Ioctl

SR-IOV device drivers that implement the IOV_GET_VER_INFO IOCTL() ioctl should set the version and the num_params fields in the iov_param_ver_info structure and return the values to the calling function. The calling function then uses the version and num_params parameters to determine the size of buffer required to get parameter descriptions using the IOV_GET_PARAM_INFO() ioctl call.
