From adcc29e56130f0f047b99528ce72b6f149643da7 Mon Sep 17 00:00:00 2001 From: "Mytnyk, Volodymyr" Date: Thu, 4 Oct 2018 15:24:56 +0100 Subject: Configure n_rxq DPDK port option when adding the port On some platform, setting n_rxq option on port separately does not work well and causes issues like port link down, so changed the logic to set n_rxq DPDK port option during adding the port to the bridge which help to resolve the problem.
