From c1ba6c325c4c7c8e0f32d9e96bc25ab172a222ee Mon Sep 17 00:00:00 2001 From: Huisong Li Date: Mon, 11 Oct 2021 17:12:46 +0800 Subject: [PATCH] app/testpmd: retain all original dev conf when config DCB When configuring DCB, testpmd retains the rx_mode/tx_mode configuration in rte_port->dev_conf. But some configurations, such as the link_speed, were not saved if they were set before configuring DCB.
