From 683d1e82a0f2caae1a9c6f1209ab4d743373a173 Mon Sep 17 00:00:00 2001 From: Igor Romanov Date: Mon, 18 Mar 2019 11:35:47 +0000 Subject: [PATCH] app/testpmd: fix stdout flush after printing stats User can specify stats period(n). The statistics should be available to user every n second. But the print_stats() function does not force stdout to be flushed, so for instance, a user reading testpmd's stdout through pipe will not be able to read it until the stdout buffer is filled.
