Status: Landed in mainline as 9c1952aeaa98 on 2021-12-30.
From: wujianguo <redacted>
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")
