Description:

		This file contains the number of virtual PTP clocks in

		use.  By default, the value is 0 meaning that only the

		physical clock is in use.  Setting the value creates

		the corresponding number of virtual clocks and causes

		the physical clock to become free running.  Setting the

		value back to 0 deletes the virtual clocks and

		switches the physical clock back to normal, adjustable

		operation.
