From b7f477920f7be7052e8d5de9ea14f61aba7597d3 Mon Sep 17 00:00:00 2001 From: Michal Jastrzebski Date: Fri, 7 Aug 2015 14:15:31 +0200 Subject: [PATCH] app/test: fix bonding mode 5 Tx check Test failed on verification if number of bytes transmitted on each slave is not less than 90% and greater than 110% of mean value of bytes transmitted thru one slave. This was verified on a real system but is difficult to achieve using virtualpmd. That's why for unit tests only, it is sufficient to verify that with high load (2 seconds transmission) all slaves are transmitting so the traffic is balanced.
