| * 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); |
