selftests: mptcp: join: validate event numbers
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") Cc: stable@vger.kernel.org Reviewed-by: Mat Martineau <martineau@kernel.org> Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
