Subject: [PATCH net 4/4] mptcp: update selftest for fallback due to OoO
Date: Thu, 27 May 2021 16:31:40 -0700 [thread overview]
Message-ID: <20210527233140.182728-5-mathew.j.martineau@linux.intel.com> (raw)
In-Reply-To: <20210527233140.182728-1-mathew.j.martineau@linux.intel.com>
From: Paolo Abeni <pabeni@redhat.com>
The previous commit noted that we can have fallback
scenario due to OoO (or packet drop). Update the self-tests
accordingly
