+Subject: selftests: mptcp: join: only check for ip6tables if needed
+
+From: Matthieu Baerts <matthieu.baerts@tessares.net>
+
+commit 016e7ba47f33064fbef8c4307a2485d2669dfd03 upstream.
+
+If 'iptables-legacy' is available, 'ip6tables-legacy' command will be
+used instead of 'ip6tables'. So no need to look if 'ip6tables' is
+available in this case.

+Cc: stable@vger.kernel.org
+Fixes: 0c4cd3f86a40 ("selftests: mptcp: join: use 'iptables-legacy' if available")
