* Name: ioctl_getipaddr / ioctl_setipaddr
* Name: ioctl_getipaddr

* Description:
* Copy IP addresses into and out of device structure
* Copy IP addresses from device structure to user memory.

* Input Parameters:
* outaddr - Pointer to the user-provided memory to receive the address.
* Actual type may be either 'struct sockaddr' (IPv4 only) or type
* 'struct sockaddr_storage' (both IPv4 and IPv6).
* inaddr - The source IP adress in the device structure.
