+ * 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);
+ *
