This command is used to by higher level applications to dynamically
control the debug logging level of the kernel module.  This is
particularly useful to collect debug information from customers filing
feedback reports for issues that are difficult to reproduce outside of a
customer's particular environement.

+=======================
+
+	Command Code:		0x0047
+	Controller Index: <controller id>
+	Command Parameters : Debug_Logging_Level (1 octet)
+
+	This command is used to set the kernel debug logging level. This
+	can be by higher level applications to facilitate dynamically
+	controlling	the logging level produced by the Bluez kernel module.
+
+	Supported Debug_Logging_Level values:
+		0 : No Logging
+		1 : All debug information.
+		All other values are reserved for future use.
+
+	When the kernel receives a value higher than the maximum supported
+	value, the kernel module shall set it's logging level to the highest
+	value it supports.
+
+	This command generates a Command Complete event on success or
+	a Command Status event on failure.
