[dpdk-dev] [PATCH] app/test-flow-perf: configurable rule batches

Georgios Katsikas katsikas.gp at gmail.com
Tue Sep 8 08:12:30 CEST 2020


* One can now configure the number of rules per batch
* Refactored flow_count variable to rules_count as it is
related to the newly added rules_batch variable
* Added default values to usage function
