6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geliang Tang geliang.tang@suse.com
commit b850f2c7dd85ecd14a333685c4ffd23f12665e94 upstream.
To avoid duplicated code in different MPTCP selftests, we can add and use helpers defined in mptcp_lib.sh.
is_v6() helper is defined in mptcp_connect.sh, mptcp_join.sh and mptcp_sockopt.sh, so export it into mptcp_lib.sh and rename it as mptcp_lib_is_v6(). Use this new helper in all scripts.
