Subject: [PATCH net-next 2/8] selftests/net: convert netns-name.sh to run it in unique namespace
Date: Tue, 19 Dec 2023 17:48:50 +0800	[thread overview]
Message-ID: <20231219094856.1740079-3-liuhangbin@gmail.com> (raw)
In-Reply-To: <20231219094856.1740079-1-liuhangbin@gmail.com>

This test will move the device to netns 1. Add a new test_ns to do this.
Here is the test result after conversion.

 # ./netns-name.sh
 netns-name.sh                           [  OK  ]
