Subject: [PATCH 1/2] netfilter: nf_tables: use skb->protocol instead of assuming ethernet header
Date: Tue, 22 Dec 2015 18:53:16 +0100
Message-ID: <1450806797-21788-2-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1450806797-21788-1-git-send-email-pablo@netfilter.org>

Otherwise we may end up with incorrect network and transport header for
other protocols.
