[PATCH net-next 05/15] selftests: mptcp: export TEST_COUNTER variable

From: Matthieu Baerts (NGI0)
Date: Fri Mar 08 2024 - 17:12:28 EST


From: Geliang Tang <tanggeliang@xxxxxxxxxx>

Variable TEST_COUNT are used in mptcp_connect.sh and mptcp_join.sh as
test counters, which are initialized to 0, while variable test_cnt are used
in diag.sh and simult_flows.sh, which are initialized to 1. To maintain
consistency, this patch renames them all as MPTCP_LIB_TEST_COUNTER,
initializes it to 1, and exports it into mptcp_lib.sh.
