3.16.7-ckt12 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Pablo Neira Ayuso <pa...@netfilter.org>
commit 749177ccc74f9c6d0f51bd78a15c652a2134aa11 upstream.
ip6tables extensions check for this flag to restrict match/target to a
given protocol. Without this flag set, SYNPROXY6 returns an error.
