From 8d4df4e120ee231b193ee588628cbf7cadcb5008 Mon Sep 17 00:00:00 2001 From: Ilya Maximets Date: Tue, 5 Jul 2016 10:20:26 +0300 Subject: [PATCH] app/testpmd: fix comment of RSS setup Since commit f2bb7ae1d204, behavior of rss_fwd_config_setup() changed and description of this function is wrong now. Also, there is a type mismatch in a loop.
