[PATCH mptcp-next v2 27/30] selftests: mptcp: add mptcp_lib_get_counter
Posted by Geliang Tang 11 months, 3 weeks ago 
The helper get_counter() in mptcp_join.sh and get_mib_counter() in
mptcp_connect.sh have the same functionality, export get_counter() into
mptcp_lib.sh and rename it as mptcp_lib_get_counter(). Use this new
helper instead of get_counter() and get_mib_counter().
