From 7e9740e0e84e21281759590ccec4e3c926eb54bf Mon Sep 17 00:00:00 2001 From: Matthieu Baerts Date: Wed, 25 Jan 2023 11:47:22 +0100 Subject: mptcp: propagate sk_ipv6only to subflows Usually, attributes are propagated to subflows as well. Here, if subflows are created by other ways than the MPTCP path-manager, it is important to make sure they are in v6 if it is asked by the userspace.
