Subject: [PATCH net-next v2 04/12] selftests: mptcp: add
mptcp_lib_ns_init/exit helpers
From: Geliang Tang <tanggeliang@...inos.cn>
Add helpers mptcp_lib_ns_init() and mptcp_lib_ns_exit() in mptcp_lib.sh
to initialize and delete the given namespaces. Then every test script
can invoke these helpers and use all namespaces.
