[PATCH net-next 09/11] selftests: mptcp: use pm_nl endpoint ops

From: Matthieu Baerts (NGI0)
Date: Fri Apr 05 2024 - 06:55:26 EST


From: Geliang Tang <tanggeliang@xxxxxxxxxx>

Use those newly added pm_nl endpoint ops helpers to replace all 'pm_nl_ctl'
commands with 'limits', 'add', 'del', 'flush', 'show' and 'set' arguments
in scripts mptcp_sockopt.sh and simult_flows.sh.

In pm_netlink.sh, add wrappers of there helpers to make the function names
shorter. Then use the wrappers to replace all 'pm_nl_ctl' commands.
