New Revision: 247317
URL: http://svnweb.freebsd.org/changeset/base/247317
Log:
Update the EWMA statistics for each intermediary rate as well as the final
rate.
This fixes two things:
* The intermediary rates now also have their EWMA values changed;
* The existing code was using the wrong value for longtries - so the
EWMA stats were only adjusted for the first rate and not subsequent
rates in a MRR setup.
TODO:
* Merge the EWMA updates into update_stats() now..
