   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);
