From fb6ac45e86668456e5750d2a1c874ca2f5526171 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Mon, 12 Jun 2023 17:31:02 +0200 Subject: [PATCH] mlxsw: spectrum_router: Access rif->dev through a helper In order to abstract away deduction of netdevice from the corresponding RIF, introduce a helper, mlxsw_sp_rif_dev(), and use it throughout. This will make it possible to change the deduction path easily later on.
