From d54725cd11a57c30f650260cfb0a92c268bdc3e0 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Wed, 16 Oct 2019 14:30:05 +0200 Subject: netfilter: nf_tables: support for multiple devices per netdev hook This patch allows you to register one netdev basechain to multiple devices. This adds a new NFTA_HOOK_DEVS netlink attribute to specify the list of netdevices. Basechains store a list of hooks.
