* This IOCTL is used to associate the current file descriptor with a
* FW Client (given by UUID). This opens a communication channel
* between a host client and a FW client. From this point every read and write
* will communicate with the associated FW client.
* Only in close() (file_operation release()) the communication between
* the clients is disconnected
*
* The IOCTL argument is a struct with a union the contains
* the input parameter and the output parameter for this IOCTL.
*
* The input parameter is UUID of the FW Client.
* The output parameter is the properties of the FW client
* (FW protocol version and max message size).
