From e35693fd13de771e1e047ffa4f799f72f1446e8d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Carlos=20Falgueras=20Garc=C3=ADa?= Date: Wed, 17 Aug 2016 16:07:09 +0200 Subject: src: Implement rule comparison MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch implements the function: bool nftnl_rule_cmp(const struct nftnl_rule *r1, const struct nftnl_rule *r2) for rule comparison. Expressions within rules need to be compared, so also has been created the function: bool nftnl_expr_cmp(const struct nftnl_expr *e1, const struct nftnl_expr *e2); Also includes all expression comparators.
