From 0f74fa5617305aa555db7cbc8c19b8eff4806efe Mon Sep 17 00:00:00 2001 From: Amit Cohen Date: Wed, 17 Mar 2021 12:35:26 +0200 Subject: [PATCH] mlxsw: Add struct mlxsw_sp_switchdev_ops per ASIC A subsequent patch will need to implement different set of operations when a port joins / leaves an 802.1ad bridge, based on the ASIC type. Prepare for this change by allowing to initialize the bridge module based on the ASIC type via 'struct mlxsw_sp_switchdev_ops'.
