NOTES.
* The stored value for avbps is scaled by 2^5, so that maximal
rate is ~1Gbit, avpps is scaled by 2^10.
* avbps is scaled by 2^5, avpps is scaled by 2^10.
* both values are reported as 32 bit unsigned values. bps can
overflow for fast links : max speed being 34360Mbit/sec
* Minimal interval is HZ/4=250msec (it is the greatest common divisor
for HZ=100 and HZ=1024 8)), maximal interval
is (HZ*2^EST_MAX_INTERVAL)/4 = 8sec. Shorter intervals
