Merge branch 'nf_tables_offload-vlan-matching-support'
Pablo Neira Ayuso says: ==================== nf_tables_offload: vlan matching support The following patchset contains Netfilter support for vlan matching offloads: 1) Constify nft_reg_load() as a preparation patch. 2) Restrict rule matching to ingress interface type ARPHRD_ETHER. 3) Add new vlan_tci field to flow_dissector_key_vlan structure, to allow to set up vlan_id, vlan_dei and vlan_priority in one go. 4) C-VLAN matching support. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
