From eb26a59232770fc6137759965437ea55d067134b Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Thu, 19 Oct 2023 12:27:13 +0200 Subject: [PATCH] mlxsw: cmd: Add CONFIG_PROFILE.{set_, }lag_mode Add CONFIG_PROFILE.lag_mode, which serves for moving responsibility for placement of the LAG table from FW to SW. Whether lag_mode should be configured is determined by CONFIG_PROFILE.set_lag_mode, which also add. Signed-off-by: Petr Machata Reviewed-by: Ido Schimmel Signed-off-by: David S.
