	  Enables additional debug messages in FunctionFS driver to be

	  output via IPC Logging mechanism. This can be useful when

	  troubleshooting transfer stalls or other general failures and

	  determine if the issue is in the kernel gadget or the userspace

	  client. Separate IPC log contexts are created for each function

	  instance at mount time.
