/*
* 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);
*
