abuse of pointer to struct mbuf type. param2 changed to u_long type and uses parameter name 'cmd' (ioctl command) param3 changed to void * type and uses parameter name 'data' param4 changed to struct ifnet * and uses parameter name 'ifp' param5 has been removed (formerly struct lwp *) and uses of 'l' have been replaced with curlwp from curproc(9). callers have had (now unnecessary) casts to struct mbuf * removed, called code has had (now unnecessary) casts to u_long, void * and struct ifnet * respectively removed. reviewed by rmind@
