| 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); |
