From 34cc6a54914f478c93e176450fae6313404f9f74 Mon Sep 17 00:00:00 2001 From: Moshe Shemesh Date: Mon, 25 Aug 2025 17:34:28 +0300 Subject: [PATCH] net/mlx5: Reload auxiliary drivers on fw_activate The devlink reload fw_activate command performs firmware activation followed by driver reload, while devlink reload driver_reinit triggers only driver reload. However, the driver reload logic differs between the two modes, as on driver_reinit mode mlx5 also reloads auxiliary drivers, while in fw_activate mode the auxiliary drivers are suspended where applicable. Additionally, following the cited commit, if the device has multiple PFs, the behavior during fw_activate may vary between PFs: one PF may suspend auxiliary drivers, while another reloads them. Align devlink dev reload fw_activate behavior with devlink dev reload driver_reinit, to reload all auxiliary drivers.
