Subject: [PATCH bpf-next 14/15] selftests/xsk: automatically restore packet stream
Date: Tue,  6 Dec 2022 10:08:25 +0100	[thread overview]
Message-ID: <20221206090826.2957-15-magnus.karlsson@gmail.com> (raw)
In-Reply-To: <20221206090826.2957-1-magnus.karlsson@gmail.com>

From: Magnus Karlsson <magnus.karlsson@intel.com>

Automatically restore the default packet stream if needed at the end
of each test. This so that test writers do not forget to do this.
