/*

 *      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=%x\n", rc, x);

 *
