Subject: [PATCH net-next 09/11] selftests: mptcp: use pm_nl endpoint ops
From: Geliang Tang <tanggeliang@...inos.cn>
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.
