Subject: [PATCH net-next v4 02/15] selftests: mptcp: add evts_get_info
helper
From: Geliang Tang <geliang.tang@...e.com>
This patch adds a new helper get_info_value(), using 'sed' command to
parse the value of the given item name in the line with the given keyword,
to make chk_mptcp_info() and pedit_action_pkts() more readable.
Also add another helper evts_get_info() to use get_info_value() to parse
the output of 'pm_nl_ctl events' command, to make all the userspace pm
selftests more readable, both in mptcp_join.sh and userspace_pm.sh.
