+ * The 82599 and the X540 do not have true 64bit nanosecond scale
+ * counter registers. Instead, SYSTIME is defined by a fixed point
+ * system which allows the user to define the scale counter increment
+ * value at every level change of the oscillator driving the SYSTIME
+ * value. For both devices the TIMINCA:IV field defines this
+ * increment. On the X540 device, 31 bits are provided. However on the
+ * 82599 only provides 24 bits. The time unit is determined by the
+ * clock frequency of the oscillator in combination with the TIMINCA
+ * register. When these devices link at 10Gb the oscillator has a
+ * period of 6.4ns. In order to convert the scale counter into
+ * nanoseconds the cyclecounter and timecounter structures are
+ * used. The SYSTIME registers need to be converted to ns values by use
+ * of only a right shift (division by power of 2). The following math
+ * determines the largest incvalue that will fit into the available
+ * bits in the TIMINCA register.
+ *
+ * PeriodWidth: Number of bits to store the clock period
+ * MaxWidth: The maximum width value of the TIMINCA register
+ * Period: The clock period for the oscillator
+ * round(): discard the fractional portion of the calculation
+ *
+ * Period * [ 2 ^ ( MaxWidth - PeriodWidth ) ]
+ *
+ * For the X540, MaxWidth is 31 bits, and the base period is 6.4 ns
+ * For the 82599, MaxWidth is 24 bits, and the base period is 6.4 ns
+ *
+ * The period also changes based on the link speed:
+ * At 10Gb link or no link, the period remains the same.
+ * At 1Gb link, the period is multiplied by 10. (64ns)
+ * At 100Mb link, the period is multiplied by 100. (640ns)
+ *
+ * The calculated value allows us to right shift the SYSTIME register
+ * value in order to quickly convert it into a nanosecond clock,
+ * while allowing for the maximum possible adjustment value.
+ *
+ * These diagrams are only for the 10Gb link period
