Miller" , Eric Dumazet , Jakub Kicinski , Paolo Abeni Cc: netdev@vger.kernel.org, mptcp@lists.linux.dev, Mat Martineau , Geliang Tang X-Mailer: b4 0.12.4 From: Geliang Tang To avoid duplicated code in different MPTCP selftests, we can add and use helpers defined in mptcp_lib.sh. check_transfer() and print_file_err() helpers are defined both in mptcp_connect.sh and mptcp_sockopt.sh, export them into mptcp_lib.sh and rename them with mptcp_lib_ prefix. And use them in all scripts. Note: In mptcp_sockopt.sh it is OK to drop 'ret=1' in check_transfer() because it will be set in run_tests() anyway.
