From cffb3d66a8e389f6e73ac25219e56664a993572a Mon Sep 17 00:00:00 2001 From: Huisong Li Date: Wed, 28 Apr 2021 14:40:43 +0800 Subject: [PATCH] app/testpmd: check DCB info support for configuration Currently, '.get_dcb_info' must be supported for the port doing DCB test, or all information in 'rte_eth_dcb_info' are zero. It should be prevented when user run cmd "port config 0 dcb vt off 4 pfc off". This patch adds the check for support of reporting dcb info.
