Subject: [libica PATCH] icastats: Fix summary option to display correct
summary information
The '--summary' option of icastats did not display correct statistics since
the introduction of per key keysize counters with libica version 4.0.0.
To display the correct summary counters, the all-key-size-counter values of an
algorithm that supports multiple key sizes must be calculated like it is done
in get_stats_data(). Adjust get_stats_data() function and friends so that it
now also can be called from get_stats_sum() and can optionally operate on a
specified statistics segment (i.e. the one where the summary statistics have
been calculated in), not just the global one.
