Subject: [PATCH] selftests/net: udpgso_bench_tx: fix dst ip argument
Date: Wed, 29 Dec 2021 18:58:10 +0800 [thread overview]
Message-ID: <ff620d9f-5b52-06ab-5286-44b945453002@163.com> (raw)
From: wujianguo <wujianguo@chinatelecom.cn>
udpgso_bench_tx call setup_sockaddr() for dest address before
parsing all arguments, if we specify "-p ${dst_port}" after "-D ${dst_ip}",
then ${dst_port} will be ignored, and using default cfg_port 8000.
This will cause test case "multiple GRO socks" failed in udpgro.sh.
Setup sockaddr after after parsing all arguments.
Fixes: 3a687bef148d ("selftests: udp gso benchmark")
Signed-off-by: Jianguo Wu <wujianguo@chinatelecom.cn>
