-       default NET_SCH_CLK_JIFFIES
-       help
-         Packet schedulers need a monotonic clock that increments at a static
-         rate. The kernel provides several suitable interfaces, each with
-         different properties:
-         
-         - high resolution (us or better)
-         - fast to read (minimal locking, no i/o access)
-         - synchronized on all processors
-         - handles cpu clock frequency changes
-
-         but nothing provides all of the above.

-config NET_SCH_CLK_JIFFIES
-       bool "Timer interrupt"
-       help
-         Say Y here if you want to use the timer interrupt (jiffies) as clock
-         source. This clock source is fast, synchronized on all processors and
-         handles cpu clock frequency changes, but its resolution is too low
-         for accurate shaping except at very low speed.

-config NET_SCH_CLK_GETTIMEOFDAY
-       bool "gettimeofday"
-       help
-         Say Y here if you want to use gettimeofday as clock source. This clock
-         source has high resolution, is synchronized on all processors and
-         handles cpu clock frequency changes, but it is slow.
-
-         Choose this if you need a high resolution clock source but can't use
-         the CPU's cycle counter.

-config NET_SCH_CLK_CPU
-       bool "CPU cycle counter"
-       depends on X86_TSC || X86_64 || ALPHA || SPARC64 || PPC64 || IA64
-       help
-         Say Y here if you want to use the CPU's cycle counter as clock source.
-         This is a cheap and high resolution clock source, but on some
-         architectures it is not synchronized on all processors and doesn't
-         handle cpu clock frequency changes.
-
-         The useable cycle counters are:
-
-               x86/x86_64      - Timestamp Counter
-               alpha           - Cycle Counter
-               sparc64         - %ticks register
-               ppc64           - Time base
-               ia64            - Interval Time Counter
-
-         Choose this if your CPU's cycle counter is working properly.
