Subject: netfilter: nft_compat: set IP6T_F_PROTO flag if protocol is set
From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>
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.
