Broadcom NICE will only be + * enabled by a NICE-aware intermediate driver, such as + * Broadcom Advanced Server Program Driver (BASP). When NICE + * is not enabled, the modified network device drivers + * functions exactly as other non-NICE aware drivers. + * + * Author: Frankie Fan + * + * Created: September 17, 2000 + * + ****************************************************************************/ +#ifndef _nicext_h_ +#define _nicext_h_ + +/* + * ioctl for NICE + */ +#define SIOCNICE SIOCDEVPRIVATE+7 + +/* + * SIOCNICE: + * + * The following structure needs to be less than IFNAMSIZ (16 bytes) because + * we're overloading ifreq.ifr_ifru. + * + * If 16 bytes is not enough, we should consider relaxing this because + * this is no field after ifr_ifru in the ifreq structure.
