Subject: [PATCH nf-next 4/4] netfilter: nf_tables: increase maximum devices number per flowtable
Date: Wed, 16 Oct 2019 14:34:31 +0200 [thread overview]
Message-ID: <20191016123431.9072-5-pablo@netfilter.org> (raw)
In-Reply-To: <20191016123431.9072-1-pablo@netfilter.org>
Rise the maximum limit of devices per flowtable up to 256. Rename
NFT_FLOWTABLE_DEVICE_MAX to NFT_NETDEVICE_MAX in preparation to reuse
the netdev hook parser for ingress basechain.
