* 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);
|
