From c9626a2cbdb20e26587b3fad99960520a023432b Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Tue, 9 Jul 2019 23:00:43 +0200 Subject: netfilter: nf_tables: add hardware offload support This patch adds hardware offload support for nftables through the existing netdev_ops->ndo_setup_tc() interface, the TC_SETUP_CLSFLOWER classifier and the flow rule API. This hardware offload support is available for the NFPROTO_NETDEV family and the ingress hook. Each nftables expression has a new ->offload interface, that is used to populate the flow rule object that is attached to the transaction object. There is a new per-table NFT_TABLE_F_HW flag, that is set on to offload an entire table, including all of its chains. This patch supports for basic metadata (layer 3 and 4 protocol numbers), 5-tuple payload matching and the accept/drop actions; this also includes basechain hardware offload only.
