Subject: [PATCH net-next v4 15/15] selftests: mptcp: add
mptcp_lib_wait_local_port_listen
From: Geliang Tang <geliang.tang@...e.com>
To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
wait_local_port_listen() helper is defined in diag.sh, mptcp_connect.sh,
mptcp_join.sh and simult_flows.sh, export it into mptcp_lib.sh and
rename it with mptcp_lib_ prefix. Use this new helper in all these
scripts.
Note: We only have IPv4 connections in this helper, not looking at IPv6
(tcp6) but that's OK because we only have IPv4 connections here in diag.sh.
