From: Wisam Jaddo Date: Thu, 4 Jun 2020 13:35:00 +0000 (+0000) Subject: app/flow-perf: add deletion rate calculation X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c12f4f217d8519582d60050a928b68a965a7b37c;p=dpdk.git app/flow-perf: add deletion rate calculation Add the ability to test deletion rate for flow performance application. This feature is disabled by default, and can be enabled by add "--deletion-rate" in the application command line options.
