6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Matthieu Baerts (NGI0)" <matttbe@xxxxxxxxxx>
commit 20ccc7c5f7a3aa48092441a4b182f9f40418392e upstream.
This test extends "delete and re-add" and "delete re-add signal" to
validate the previous commit: the number of MPTCP events are checked to
make sure there are no duplicated or unexpected ones.
A new helper has been introduced to easily check these events. The
missing events have been added to the lib.
The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.
Fixes: b911c97c7dc7 ("mptcp: add netlink event support")

[ Conflicts in mptcp_join.sh and mptcp_lib.sh, due to commit
38f027fca1b7 ("selftests: mptcp: dump userspace addrs list") -- linked
to a new feature, not backportable to stable -- and commit
23a0485d1c04 ("selftests: mptcp: declare event macros in mptcp_lib")
-- depending on the previous one -- not in this version. The conflicts
in mptcp_join.sh were in the context, because a new helper had to be
added after others that are not in this version. The conflicts in
mptcp_lib.sh were due to the fact the other MPTCP_LIB_EVENT_*
constants were not present. They have all been added in this version
to ease future backports if any. ]
