Subject: [PATCH net-next 8/8] selftests/mptcp: add diag listen tests
From: Florian Westphal <fw@...len.de>
Check dumping of mptcp listener sockets:
1. filter by dport should not return any results
2. filter by sport should return listen sk
3. filter by saddr+sport should return listen sk
4. no filter should return listen sk
