Subject: [iptables PATCH v2 15/17] xtables: arptables ignores wrong -t values
Date: Thu, 30 Sep 2021 16:04:17 +0200 [thread overview]
Message-ID: <20210930140419.6170-16-phil@nwl.cc> (raw)
In-Reply-To: <20210930140419.6170-1-phil@nwl.cc>
Legacy arptables allows arbitrary values passed after '-t' and just uses
table 'filter' instead. Mimick this behaviour by just ignoring the
parameter after invert flag checking (which legacy arptables indeed
does).
