From f1bcde88c4288b15c1e6e733378e904ff9b1fdbd Mon Sep 17 00:00:00 2001 From: Dengdui Huang Date: Thu, 25 May 2023 15:03:02 +0800 Subject: [PATCH] app/testpmd: fix segment fault with invalid queue ID When input queue ID is invalid, it will lead to Segmentation fault, like: dpdk-testpmd -a 0000:01:00.0 -- -i testpmd> show port 0 txq/rxq 99 desc 0 status Segmentation fault dpdk-testpmd -a 0000:01:00.0 -- -i testpmd> show port 0 rxq 99 desc used count Segmentation fault This patch fixes it.
