> Subject: [PATCH v2] app/testpmd: fix burst stat reporting
> 
> When RTE_TEST_PMD_RECORD_BURST_STATS is enabled, testpmd collects
> burst statistics and includes them in the port stats report.  The summary
> should include top 2 most frequent burst sizes, but there is a bug in finding
> the top-2.  During the scan of burst size counts, the
> top-2 can change only if top-1 also changes.
> 
> Added logic to update the top-2 if current burst size is larger than existing
> top-2, but smaller than existing top-1.
> 
> Fixes: af75078fece3 ("first public release")
