Subject: [PATCH nf] netfilter: nft_compat: set IP6T_F_PROTO flag if protocol is set
Date: Sat, 21 Mar 2015 19:36:58 +0100 [thread overview]
Message-ID: <1426963018-6838-1-git-send-email-pablo@netfilter.org> (raw)
ip6tables extensions check for this flag to restrict match/target to a
given protocol. Without this flag set, SYNPROXY6 returns an error.
