Instead of letting secondary processes select their own function, they now used the function selected by the primary process. However, the primary process only selects the function at device start, so if the primary process hadn't started the device by the time the secondary process was selecting its Rx burst function, the secondary process would not select the correct function. This commit addresses this issue by allowing the secondary process to select the path if the device has not been started yet.
