Since the commit mentioned below, 'mptcp_join' selftests is using IPTables to add rules to the Filter table for IPv6. It is then required to have IP6_NF_FILTER KConfig. This KConfig is usually enabled by default in many defconfig, but we recently noticed that some CI were running our selftests without them enabled.
