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);
