Subject: [PATCH net-next 31/38] selftests/net: convert toeplitz.sh to run it in unique namespace
Date: Fri, 24 Nov 2023 17:27:29 +0800	[thread overview]
Message-ID: <20231124092736.3673263-32-liuhangbin@gmail.com> (raw)
In-Reply-To: <20231124092736.3673263-1-liuhangbin@gmail.com>

]# ./toeplitz.sh -i eno1 -t -6

count: pass=0 nohash=0 fail=0
./toeplitz: too few frames for verification
