* Description:
* Find a previously registered network device by its position in the

* to enumerate network devices: There could be changes to the list of
* registered device causing a given index to be meaningless (unless, of
* course, the caller keeps the network locked).

* Parameters:
* index - the index of the interface to file
*
* Returned Value:
* Pointer to driver on success; NULL on failure. This function can only
* fail if there are fewer registered interfaces than could be indexed.

* Assumptions:
* Called from normal user mode
