From 560e02ee5237920a9bc0c8dd148308f04e1582d3 Mon Sep 17 00:00:00 2001 From: Ivan Boule Date: Fri, 16 May 2014 10:58:41 +0200 Subject: [PATCH] app/testpmd: configure RSS without restart The function cmd_config_rss_parsed() associated with the command "port config rss all" required to first stop all ports, in order to then entirely re-configure all ports with the new RSS hash computation parameters. Use now the new function rte_eth_dev_rss_hash_conf_update() that dynamically only changes the RSS hash computation parameters of a port, without needing to previously stop the port.
