Subject: [PATCHv3 net] selftests: fib_tests: mute cleanup error message
Date:   Thu, 18 May 2023 12:37:59 +0800
Message-Id: <20230518043759.28477-1-po-hsu.lin@canonical.com>
MIME-Version: 1.0

In the end of the test, there will be an error message induced by the
`ip netns del ns1` command in cleanup()

  Tests passed: 201
  Tests failed:   0
  Cannot remove namespace file "/run/netns/ns1": No such file or directory

This can even be reproduced with just `./fib_tests.sh -h` as we're
calling cleanup() on exit.

Redirect the error message to /dev/null to mute it.

V2: Update commit message and fixes tag.
V3: resubmit due to missing netdev ML in V2

Fixes: b60417a9f2b8 ("selftest: fib_tests: Always cleanup before exit")
