From 651cfee91a8f42336b9d794c838b9f4f480308c9 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Thu, 12 Apr 2018 11:31:42 +0200 Subject: xtables-compat: pass correct table skeleton This always uses xtables_ipv4 (which is same as _ipv6). Pass the correct skeleton instead, this is needed to handle ebtables correctly from xt-translate, as it doesn't use ip/ip6 tables.
