From bf3688f1e81632daa2a88dc7bd7120b46ed35d4e Mon Sep 17 00:00:00 2001 From: Wisam Jaddo Date: Thu, 4 Jun 2020 13:34:59 +0000 Subject: [PATCH] app/flow-perf: add insertion rate calculation Add insertion rate calculation feature into flow performance application. The application now provide the ability to test insertion rate of specific rte_flow rule, by stressing it to the NIC, and calculate the insertion rate. The application offers some options in the command line, to configure which rule to apply. After that the application will start producing rules with same pattern but increasing the outer IP source address by 1 each time, thus it will give different flow each time, and all other items will have open masks. The current design have single core insertion rate.
