Subject: [PATCH net-next v3 2/4] selftests: net: udpgso_bench_rx/tx: Stop when wrong CLI args are provided
Date: Tue, 31 Jan 2023 20:53:18 +0000	[thread overview]
Message-ID: <20230131205318.475414-2-andrei.gherzan@canonical.com> (raw)
In-Reply-To: <20230131205318.475414-1-andrei.gherzan@canonical.com>

Leaving unrecognized arguments buried in the output, can easily hide a
CLI/script typo. Avoid this by exiting when wrong arguments are provided to
the udpgso_bench test programs.

Fixes: 3a687bef148d ("selftests: udp gso benchmark")
