selftests: mptcp: dump userspace addrs list
[ Upstream commit 38f027fca1b724c6814fff4b8ad16b59c14a3e2a ]
This patch adds a new helper userspace_pm_dump() to dump addresses
for the userspace PM. Use this helper to check whether an ID 0 subflow
is listed in the output of dump command after creating an ID 0 subflow
in "userspace pm create id 0 subflow" test. Dump userspace PM addresses
list in "userspace pm add & remove address" test and in "userspace pm
create destroy subflow" test.
