From: Ivan Boule Date: Fri, 16 May 2014 08:58:41 +0000 (+0200) Subject: app/testpmd: configure RSS without restart X-Git-Tag: spdx-start~10782 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=560e02ee5237920a9bc0c8dd148308f04e1582d3;p=dpdk.git 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.
