From b46c1f3f5e079d2b6cb2845715942fe75304e498 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Thu, 19 Oct 2023 12:27:20 +0200 Subject: [PATCH] mlxsw: spectrum: Set SW LAG mode on Spectrum>1 On Spectrum-2, Spectrum-3 and Spectrum-4 machines, request SW responsibility for placement of the LAG table. On Spectrum-1, some FW versions claim to support lag_mode field despite quietly ignoring any settings made to that field. Thus refrain from attempting to configure lag_mode on those systems at all.
