		Run self tests when initializing the Bluetooth subsystem. This
		is a developer option and can cause significant delay when booting
		the system.

		When the Bluetooth subsystem is built as module, then the test
		cases are run first thing at module load time. When the Bluetooth
		subsystem is compiled into the kernel image, then the test cases
		are run late in the initcall hierarchy.
