1 | /* |
| 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); | |
