- * ioctl's for the Digi Intl. RightSwitch
- *
- * These network driver ioctl's are a bit obtuse compared to the usual
- * ioctl's for a "normal" device driver. Hey, I didn't invent it.
- *
- * Typical use:
- *
- * struct ifreq ifr;
- * DGRS_IOCTL ioc;
- * int x;
- *
- * strcpy(ifr.ifr_name, "eth1");
- * ifr.ifr_data = (caddr_t) &ioc;
- * ioc.cmd = DGRS_GETMEM;
- * ioc.len = sizeof(x);
- * ioc.data = (caddr_t) &x;
- * rc = ioctl(fd, DGRSIOCTL, &ifr);
- * printf("rc=%d mem=%xn", rc, x);
- *
