Subject: [iptables PATCH] ebtables: Avoid dropping policy when flushing
Date: Wed, 15 Sep 2021 17:44:13 +0200 [thread overview]
Message-ID: <20210915154413.32598-1-phil@nwl.cc> (raw)
Unlike nftables, ebtables' user-defined chains have policies -
ebtables-nft implements those internally as invisible last rule. In
order to recreate them after a flush command, a rule cache is needed.
