[ Upstream commit 34cc6a54914f478c93e176450fae6313404f9f74 ]
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.
