From 016e7ba47f33064fbef8c4307a2485d2669dfd03 Mon Sep 17 00:00:00 2001 From: Matthieu Baerts Date: Tue, 25 Jul 2023 11:34:55 -0700 Subject: [PATCH 1/2] selftests: mptcp: join: only check for ip6tables if needed 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.
