Subject: [PATCH nf] netfilter: nf_tables: use skb->protocol instead of assuming ethernet header
Date: Tue, 15 Dec 2015 21:29:16 +0100 [thread overview]
Message-ID: <1450211356-10927-1-git-send-email-pablo@netfilter.org> (raw)
Otherwise we may end up with incorrect network and transport header for
other protocols.
