From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ido Schimmel Subject: [PATCH net-next 07/17] mlxsw: spectrum_acl: Enable C-TCAM only mode in eRP core Date: Wed, 25 Jul 2018 09:23:56 +0300 Message-ID: <20180725062406.3342-8-idosch@mellanox.com> References: <20180725062406.3342-1-idosch@mellanox.com> Mime-Version: 1.0 Content-Type: text/plain Cc: davem@davemloft.net, jiri@mellanox.com, mlxsw@mellanox.com, Ido Schimmel To: netdev@vger.kernel.org Return-path: Received: from mail-eopbgr70081.outbound.protection.outlook.com ([40.107.7.81]:51633 "EHLO EUR04-HE1-obe.outbound.protection.outlook.com" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1728358AbeGYHfH (ORCPT ); Wed, 25 Jul 2018 03:35:07 -0400 In-Reply-To: <20180725062406.3342-1-idosch@mellanox.com> Sender: netdev-owner@vger.kernel.org List-ID: Currently, no calls are performed into the eRP core, but in order to make review easier we would like to gradually add these calls. Have the eRP core initialize a region's master mask to all ones and allow it to use an empty eRP table. This directs the lookup to the C-TCAM and allows the C-TCAM only mode to continue working.
