From 8251786f3d8158b4cc0dcc995a6c5fe58c908b6d Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" Date: Sat, 27 Jul 2024 12:10:32 +0200 Subject: [PATCH] man: mptcp: 'port' has to be used with 'signal' That's what is enforced by the kernel: the 'port' is used to create a new listening socket on that port, not to create a new subflow from/to that port. It then requires the 'signal' flag.
