From 74cccc3d38438b346e40a4f8133cff3f0839ff84 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Tue, 30 Jun 2020 19:21:11 +0200 Subject: netfilter: nf_tables: add NFTA_CHAIN_ID attribute This netlink attribute allows you to refer to chains inside a transaction as an alternative to the name and the handle. The chain binding support requires this new chain ID approach.
