[PATCH 1/2] netfilter: nf_tables: use skb->protocol instead of assuming ethernet header

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2015-12-22 17:53:16
Also in: netfilter-devel
Subsystem: netfilter, networking [general], the rest · Maintainers: Pablo Neira Ayuso, Florian Westphal, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

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