From 25340d5342a1f0c34c7e9c1fb8c2becc7e70fa31 Mon Sep 17 00:00:00 2001 From: Chengchang Tang Date: Fri, 25 Sep 2020 20:47:18 +0800 Subject: [PATCH] app/testpmd: fix descriptor id check The number of desc is a per queue configuration. But in the check function, nb_txd & nb_rxd are used to check whether the desc_id is valid. nb_txd & nb_rxd are the global configuration of number of desc. If the queue configuration is changed by cmdline liks: "port config xx txq xx ring_size xxx", the real value will be changed. This patch use the real value to check whether the desc_id is valid. And if these are not configured by user. It will use the default value to check it, since the rte_eth_rx_queue_setup & rte_eth_tx_queue_setup will use a default value to configure the queue if nb_rx_desc or nb_tx_desc is zero.
