From c20580c21f80d676f6e128eea4dc482c4e51b265 Mon Sep 17 00:00:00 2001 From: Nir Dotan Date: Mon, 10 Dec 2018 07:11:43 +0000 Subject: [PATCH] mlxsw: spectrum_acl: Support rule creation without action creation Up until now, when ACL rule was created its action was created with it. It suits well for tc flower where ACL rule always needs an action, however it does not suit multicast router, where the action is created prior to setting a route, which in Spectrum-2 is actually an ACL rule. Add support for rule creation without action creation. Do it by adding afa_block argument to mlxsw_sp_acl_rule_create, which if NULL then an action would be created, also add an indication within struct mlxsw_sp_acl_rule_info that tells if the action should be destroyed when the rule is destroyed.
