From 9a617399d5e0776b43f093b9d63d10f72e882fee Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Wed, 28 Jul 2021 17:53:53 +0200 Subject: [PATCH] doc: ebtables-nft.8: Adjust for missing atomic-options Drop any reference to them (and the environment variable) but list them in BUGS section hinting at ebtables-save and -restore tools.
