   2 *      ioctl's for the Digi Intl. RightSwitch
   3 *
   4 *      These network driver ioctl's are a bit obtuse compared to the usual
   5 *      ioctl's for a "normal" device driver.  Hey, I didn't invent it.
   6 *
   7 *      Typical use:
   8 *
   9 *      struct ifreq    ifr;
  10 *      DGRS_IOCTL      ioc;
  11 *      int             x;
  12 *
  13 *      strcpy(ifr.ifr_name, "eth1");
  14 *      ifr.ifr_data = (caddr_t) &ioc;
  15 *      ioc.cmd = DGRS_GETMEM;
  16 *      ioc.len = sizeof(x);
  17 *      ioc.data = (caddr_t) &x;
  18 *      rc = ioctl(fd, DGRSIOCTL, &ifr);
  19 *      printf("rc=%d mem=%x\n", rc, x);
